How to Improve the Reliability of Electric Power Equipment with the Correct Transformer Oil

Tierra Fuller, ,

Transformer oils have certain technical and chemical parameters. These parameters define the scope of the oil’s applications and use.

The “Dissipation Factor” is one of the most important indications of oil quality and is a measure of the oil’s dielectric strength.  Aging causes oil to lose its performance capabilities and poses a threat to the safe operation of oil filled equipment.  Dielectric strength testing is a safety concern and must never be neglected.

The actual dielectric strength of the oil is mostly affected by the presence of solid particles, moisture, and other contaminates.  It is therefore, important to remove solid particles, water and other contaminates from transformer insulating oil to maintain the operating performance of the oil.  The best way to ensure the purity of your transformer oil is to use the GlobeCore Process performed by one of its various oil purification or oil regeneration units.

Another performance characteristic of oil is the oil’s viscosity rating.  An oil’s viscosity rating indicates the oil’s “resistance to flow” or “speed of flow” as measured through a viscometer.  The viscosity, or thickness of the oil can also affect the oil’s ability to transfer heat and cool the transformer.

Setting temperature and flashpoint temperature both help to indicate the allowable range of oil operation.  A “Low Setting” temperature is important when the oil is used in extremely cold climates.  A high oil flashpoint is important for reducing the potential fire safety concerns.

Another important quality of the oil is its oxidation stability, i.e. the ability to maintain its properties during prolonged use.  Oxidation stability is influenced by many factors, both internal such as antioxidant additives, reaction with metals, formation of gases in the oil, etc., and external factors such as moisture, air and temperature.  This parameter is important for the service life of both the oil and oil filled equipment.

Many oils, e.g. GK and TKp contain antioxidant additives which can extend the service life of oil to as long as 20-25 years.

Purchasing transformer oil from manufacturers and traders is not a problem these days.  Each company is competing and attempting to sell at the lowest price and offer the best service.

Transformer oil is an indispensible part of the insulation system of electric power transformers and other electrical equipment.  High purity and low viscosity are key in allowing your selected oil to be used in electric power transformers.

Depending on the actual equipment, transformer oils function as a dielectric liquid or, for instance, as an arc-extinguishing media in switching devices.

Quality oil has high dielectric strength, a low setting point, a high flash point, high oxidation stability, and the availability of convenient and practical transportation vessels.  High quality oil significantly extends reliable operation of oil filled electric equipment.

 

Above all, the oil in transformers and electrical equipment must be kept clean and free from moisture in order to provide the best possible service to your electrical equipment and prevent the need for unscheduled maintenance events.

It’s time to get with the Process.  The GlobeCore Process!

 

 

Which kind of Transformer Oil Should my Company Buy?

Tierra Fuller, , , , , ,

A great number of manufacturers and distributors of transformer oils operate in international and national markets.

Transformer insulating oil is a dielectric liquid that is intended for cooling and insulating electric power transformers and other high voltage equipment.  Transformers remain an indispensible part of the electric power generation and transmission industry.

In scientific terms, transformer oil is a product of crude oil refining.  The performance properties of transformer oil depend heavily on the quality and parameters of the raw material.  The performance of the oil is defined by the positive and negative properties of the crude oil.  Chemical composition of oil is quite complex.  It includes the following components: paraffin (10-15%), naphtenes or cycloparaffins (60-70%), aromatic hydrocarbons (15-20%), asphalt (1-2%), sulfuric compounds (<1%), nitric compounds (<0.8%), naphtenic acids (<0.02%) and antioxidation additive (0.5 – 0.5%).

Transformer oils must be highly resistant to oxidation and must not form sludge or emulsify when coming in contact with water.  Anti-oxidation additives are an important component and can be found in virtually all types of transformer oil.  When selecting an oil for your equipment, be sure to look for oils that have good antioxidant additives included since they will inhibit the oxidation process considerably better than uninhibited oils.

The efficiency of such additives is based on the ability of the additives to react with active peroxide radicals that form as the result of hydrocarbon oxidation reaction and are the primary carriers.  The presence of additives in transformer insulating oils slows the aging of the oil.  As soon as the additive is depleted, the oil ages in about the same amount of time as an oil without the the antioxidant additives.  Without the additives, the oil aging process will accelerate.

Two of the main characteristics of transformer oil are its viscosity and density.  These have a pronounced affect on the function of the oil.  Higher viscosity may mean better dielectric strength, but may reduce the ability of the oil to transfer heat and cool the transformer.  Optimal kinetic viscosity of the oil at 20 ̊C is about 28-30×10-6 m2/second.

The oil’s “Dissipation Factor” is responsible for the oil’s dielectric properties and protects the transformer’s electrical system from possible short circuits.

These and the other characteristics of transformer oil are improved by the use of high quality crude oil, deep refining and introduction of additives that increase the oil’s oxidation stability and reduce corrosion.

When oil is significantly oxidized due to the influence of water, solids, air and other gases, and high temperatures, the oil should be replaced.  If the degradation of the oil’s properties is not detected in time, transformers can and will fail.  When oil decays, it can no longer serve as a dielectric insulator and starts to react with the metal of the transformer tank and hinders cooling and may lead to short circuits.

The following are some of the different kinds of oils that may be purchased in the local market:

VG type oil is made from paraffinic crude oil by a catalytic process with the addition of an antioxidant  additive.  It is a good dielectric and is rather stable against oxidation.  It is mostly used in higher voltage equipment.

GK type oil is made of sulfuric paraffinic oils by hydrocracking.  It also contains ionol, an antioxidant, that ensures good stability and dielectric properties of the oil.  It is another kind of oil used in higher voltage systems.

TKp oil is made from low-sulfur naphtenic crude by an acid-alkali purification process.  The oil also contains antioxidant additives.  This oil is recommended for equipment with voltage up to 500 kV.

Oil selection depends not only on the type of electric equipment you are using, but also on the individual requirements of the facility.  Most of transformer oils are universal.  In all cases, the correct selection of oil type with consideration of local climatic and physical operating conditions ensures reliable and stable operation of electric power equipment such as high voltage transformers and switch gear.

Quality Assurance: Methods of Transformer Oil Testing

Tierra Fuller, , ,

The performance characteristics of transformer insulating oil are monitored and tested at several stages during its service life.  Regular monitoring of the oil’s quality and condition is a part of the process of servicing electric power equipment. The condition of the oil, its purity and contamination level will greatly help in indicating the condition of the transformer’s solid insulation.  It is therefore, essential to the life of the transformer to periodically monitor the condition of the insulating oil.  The heart of the transformer is the solid insulation, but the insulating oil is the life blood of the transformer.  Without the life blood, the heart will die.

The ability of insulating oil to maintain its original performance characteristics during long term operation of electric equipment is referred to as “oil stability.”  If the electric power equipment has no defects and operates in accordance with design and expectations, the performance characteristics of new oil will change and degrade slower.  When new, transformer oil has a very light color and complies with performance standards that include dielectric strength and other important characteristics.  During the course of the oil’s service life, the stability of the oil decreases and visible changes occur and oil’s color slowly becomes darker and darker.

Contaminated oil usually has a high ash content, increased acidity and presence of low molecular acids.  Acidic sludge forms in contaminated oil and aggressively attacks the cellulose insulation and reacts with the metals of the transformer’s other internal components.

Timely oil monitoring and oil analysis programs can identify when the oil needs to be changed or serviced through an oil purification and/or oil regeneration process.  Servicing the oil before it becomes aggressive against the solid insulation is the key to extending the service life of your transformers.

The main physical and chemical properties tested are the oil’s dielectric strength, dissipation factor, flashpoint, color, amount of solid particulate matter, water content, gas content and the oil’s acid number.

Dielectric strength is one of the most important indications of oil stability and this is often the first test performed.  The “dielectric breakdown test” is calculated as an average of five breakthroughs achieved in a standard discharger with two electrodes submersed in the oil at 2.5 mm distance from each other.  Six breakthroughs are achieved in the test and the last five are averaged.  If the oil is fresh, the lowest allowable breakthrough voltage is 30 kV.  In some transformers, that meets the minimum operating standard.

Decreasing dielectric strength is caused by contamination of the oil by gas, moisture, cellulose fibers or other particulate matter.

A similar process is used to calculate the oil’s “dissipation factor.”  It is the the oil’s ability to neutralize energy, prevent breakthroughs and cool the transformer.   It is a characteristic of the oil’s quality and purity and acidity.  In general, an increased dissipation factor means degradation of the oil’s dielectric capabilities.

The color of transformer oil changes from light yellow to cloudy brown under the influence of temperature, contaminants and electric current.  The color is not in itself an indication of any specific problem, but a dark color is usually an indication of aged and/or contaminated oil.

The presence of solid particles in the oil and the acid number of the oil are two related oil purity characteristics.  Unsolved materials accumulated in the oil in the form of sludge or suspended particles (fibers, dust, solved paint, metal particles, ash etc) degrade the oil’s dielectric properties and promote oil oxidation.  The more particles that are present in the oil, the faster the oil ages. The acid number is expressed as milligrams of KOH required to neutralize all acids in a gram of oil and indicates the degree of oil aging.  A normal and acceptable acid number is 0.25 mg KOH/g, while the limit of contaminant content is 515 parts per million (ppm).

Moisture and gas content in transformer oil must be tested for thoroughly.  Water and gases are very damaging to your transformer insulation system and are two main cause of the oxidation process and oil aging process.

Moisture and water content is measured as amount of hydrogen when reacting the oil with calcium hydride in a certain period of time.  Gas content is measured by an absorptiometric analyzer or a chromatographer.

The oil’s flashpoint and the oil’s setting point are two indications of the general fire safety of the oil and the oil’s ability to operate in adverse temperature conditions both hot and cold.

The are distinct advantages of testing and analyzing transformer oil before starting your electric power equipment and during scheduled maintenance events.  Oil testing allows the operator to determine the equipment’s operating efficiency, conditions and the possibility of future malfunctions.  If the purity and quality standards are followed, the equipment will be less likely to experience failures and downtime and unscheduled maintenance and repair costs.

Classification of New Transformer Insulating Oil Testing

Tierra Fuller, , , , , ,

The conditions in which insulating oil is used in transformers, switches, and other high voltage equipment are rather demanding on the performance characteristics of the insulating oil.  During the service life of the oil, it is heated by currents, contaminated by particles of solid insulation and chemical reactions with the internal surfaces of the equipment.  Each of these separately and together significantly accelerate the aging of transformer oil and can make the oil harmful to the equipment.  This is especially true with regards to the transformer insulating paper.

A sample of transformer oil is taken from the lower part of the transformer oil tank after rinsing the drain opening with oil.  The sampling vessel must be clean and very dry or the testing results will not reflect the true condition of the oil being tested.

Local and international standards define certain parameters by which the oil must comply.  Oil analysis and testing should be performed directly before placing oil into the electric power equipment.

New transformer oil is also tested before being placed into transformers.  The purity and quality guaranteed by the manufacturer of the oil does not prevent water, air and solid particles from entering the oil during handing and storage.  You cannot assume that the new oil is free from contaminates and moisture.  The oil must be properly analyzed immediately prior to use to ensure the proper operation of your electrical equipment

Before a transformer is energized, the oil in the transformer must be briefly tested for minimum dielectric strength levels, solid particulate matter, acidity and flashpoint.  If different brands of oil are used in the transformer, the final blend must be tested for stability.  The blended oil fill should not be inferior in stability to any of the separate oils with the lowest stability value.

Used oil must be tested according to standards that have been set for the operation of industrial equipment that it will be used in.

Before testing, the vessel, containing the oil sample, is inverted and turned slowly around several times to eliminate air bubbles from the oil sample.  A ceramic oil test vessel with electrodes is filled three times.  Oil is poured on the walls of the vessel in a thin stream so as to prevent formation of air bubbles.  The level of oil in the vessel must be at least 15 mm higher than the top of the electrodes.

Transformer oil is allowed to settle in the vessel for 15-20 minutes for air bubble removal.  The voltage is then gradually increased at the rate of 1 – 2 kV per second.  After a breakthrough is achieved (spark between the electrodes), voltage is recorded and then dropped to zero.  Six tests are performed and the average of the last five tests is taken.  The first breakthrough is not averaged in since it was only performed as a guide.

After each breakthrough, carbon particles are removed from the space between the electrodes by clean glass or metal rods.  The liquid is then allowed to settle for 10 minutes before performing the next test.

The transformer oil sampling process will vary from facility to facility depending on the equipment used and purity requirements of the equipment and oil being tested.

At any rate, a timely oil analysis program may well prevent significant costs and losses for your company.

Transformer Oil Storage Tanks

Tierra Fuller, , , , , ,

In power transformers and in electric equipment in general, oil is used to insulate and to cool.  The use of various types of oil for power systems is governed by internationally recognized standards.  The purpose of the uniform standards is to keep electric power equipment and systems in good working condition.  Of course, this depends on the performance characteristics and general condition of the transformer insulating oil.

Any business that uses oil must be concerned with the issue of oil storage and disposal.  This is especially important for the energy sector and the electric power generating and transmission industry.

Transformer insulating oil may come from the factory or substation in more than one condition.  Even when the oil is fresh from the manufacturer, it is possible that undesirable amounts of moisture and gases accumulated in the oil during transportation.  Transformer oil delivered from the manufacturer and purified to comply with the performance standards is usually stored in liquid storage tanks at maintenance facilities.  Regardless of the condition of the oil, whether it is new or used, it must be stored in a safe and leak proof container.

For the purposes of fire safety, the manufacturer must strictly adhere to national safety and fire prevention standards.  The actual method of storage however, and the availability of specially equipped buildings, tanks, and service equipment can vary greatly depending on location, climate and country.

A wide range of different oil storage tanks can be found in the local and international markets.  There are soft tanks that can drain and store oil more quickly reducing transformer servicing and possible downtime.  But, these types of tanks are better suited for transporting oil to interim storage facilities.

For actual storage of liquids, the most widely used tanks are vertical cylindrical tanks that are equipped with leveling quality controls, agitation systems, temperature sensors and built-in maintenance systems.

A vertical insulated tank is made of steel with heated circulation pipes below the surface.  For tank maintenance and servicing, a ladder is mounted on the tank with a protective rail along the top. Temperature is monitored by a thermistor installed in the bottom of the tank that displays the temperature on the tank’s control panel.  The heat exchange system is made of an array of pipes and insulation jackets.

Proper oil storage systems should be designed to keep the oil in good condition and preserve the oil’s performance characteristics.   Proper stored oil maintenance will help in eliminating the costs associated with additional purification and regeneration due to premature aging of the oil while being stored before use in your electric power equipment.

 

Methods of Transformer Oil Purification

Tierra Fuller, , , ,

Transformer oil serves to insulate the energized parts and components of electric power transformers and also acts as a heat transfer medium.  Additionally, it  protects the solid insulation from damaging moisture.  Besides transformers, insulting oil is used in switches, high voltage capacitors and power cables.  In switches, the oil acts as an arc extinguisher preventing fires and possible explosions.

Over the course of the transformer’s service life, that may span many years of operation, the insulting oil will accumulate various contaminants that adversely affect the oil’s performance characteristics.  Once the insulating oil’s performance characteristics have been diminished, the transformer’s solid insulation will be in greater risk of failure.  In order to restore them, the oil must be purified of foreign substances and contaminates (water, gases and solid particles).  Today, we’d like to look into the methods of transformer oil purification.  Different methods of purification can be used depending on the substance(s) that need to be removed from the oil.

Centrifugal purification is a method for water removal.  It separates unwanted materials, including water and moisture, under centrifugal force.  The main advantage of this method is the relatively high rate of water removal.  There are however, several drawbacks to this method that include; (1) a low degree of overall purification of the oil; and (2) complexity and the necessity for constant presence of service personnel supervising the process.

Another method for water removal is adsorption purification.  The biggest advantage of this method is its simplicity.  The drawbacks are: (1)  the dependency of the purification rate on the type of sorbent used; (2) the need to dispose of used sorbent and the potential environmental risks; and (3) the high quality requirement to input oil and the low rate of processing capacity.

The difference between he boiling point of water and oil is the essence of thermovacuum drying. The oil to be purified goes into a special chamber with low pressure.  In such conditions water evaporates at room temperatures.  The method allows for high efficiency purification.  It is very reliable and requires no complex adjustments.  The main drawback is the relatively low rate of water removal.

The above methods may also be used for removal of gases, solids and acids from transformer insulating oil,  e.g. thermovacuum purification is also a good method for removing unwanted gasses.  Centrifugal purification can also remove solid particles.  Single and multiple use filters with a high degree of purification are also used for the same purpose. Such filters must be replaced from time to time.  Acidity of the oil is decreased by the adsorption method and has become a highly desirable process for a more complete maintenance service for your electric power transformers.

The most modern and cost effective method for performing transformer maintenance is the industry leading GlobeCore Process which uses a Fuller’s Earth sorbent filtering system.  The GlobeCore Process uses the adsorption method to not only purify the transformer insulating oil, but to completely “regenerate” the oil by removing the contaminates and moisture from the entire transformer and not just the oil.

Unlike the older adsorption methods, the GlobeCore Process has eliminated the need to dispose of spent sorbent materials through the development and use of an automatic sorbent reactivation system.  This technological breakthrough has now made the GlobeCore Process of oil purification and regeneration the most efficient and cost effective transformer maintenance system in the world.

Expert Opinion about the Classes of Hydraulic Oil Purity

Preventive Maintenance to Avoid Corrective Maintenance

Reliable operation of hydraulic equipment, widely used in various industrial facilities, depends mostly on the quality and purity of the internal cooling and lubrication oil.  Industrial machines normally operate under heavy loads and sometimes they operate under very difficult environmental conditions.  Regular maintenance of industrial equipment therefore, can allow maintenance personnel to detect possible equipment malfunctions in a timely manner.  The the essence of Preventive Maintenance is the avoidance of having to perform Corrective Maintenance.

The Problem

The presence of solid particles in oil and hydraulic fluids can quickly degrade the oil and the fluids in your hydraulic equipment.  Also known as particulate matter, among such particles, 70-85% are quartz,  10–15% are aluminum oxide, and  5–10% are iron oxide.  Contamination of hydraulic oil also disrupts the operation of your safety and regulation valves besides causing damage to your hydraulic system.

Although replacing used and/or contaminated oils and fluids is helpful, the complete replacement of oils and fluids is not a complete solution.  That is because the hydraulic system itself is most likely contaminated by metals and sludge.  These “remain behind contaminates” will actually contaminate fresh oil as soon as it is placed into the hydraulic system thereby negating most of the benefits of replacing the oil.  The new oil can also be contaminated during incorrect transportation, storage, handling, and filling of equipment.

Another important point, with regards to your maintenance program, concerns the filtering system of your hydraulic equipment.  The filters built into the hydraulic systems cannot, and do not ensure the required purification of oil circulating in your hydraulic system.

Oil purity class is not an indication of its compatibility with certain industrial equipment types.  Also, a specific purity class cannot give a precise answer as to the oil’s reliable operation.  Equipment loads will always have a direct influence on the rate of degradation of the oil.

The Solution

For reliable operation of hydraulic fluid systems and for the prevention of malfunctions caused by contaminated and degraded oils and fluids, it is necessary to use hydraulic oil purification equipment as part of a comprehensive scheduled maintenance program.

Selection criteria of such systems include consideration of the following attributes: (1) low filtration and regeneration costs; (2) reduction of repair and maintenance costs; (3) high purity level of the processed oil; (4) removal of sludge and contaminants from oil tanks and equipment reservoirs; (5) flexibility through a mobile or stationary design; and (6) compliance with international fire and health regulations.

The Best Solution

In order to provide the hydraulic equipment industry with machines that meet the requirements of the above listed criteria, GlobeCore has developed its line of UVR type units for oil purification and regeneration.  These plants are an efficient one-stop solution for a whole array of filtration and service equipment problems.  One GlobeCore UVR unit on a mobile platform can quickly service several machines regardless of location.  It can easily move around your facility and does not require readjustment for different kinds of oil or equipment.

The use of oil purification and regeneration equipment produced and supplied by GlobeCore increases hydraulic system reliability, reduces your maintenance costs, and extends the service life of your valuable hydraulic equipment.  The GlobeCore Process is a complete regeneration and filtration process and restores your hydraulic oil to its original new specs and reduces the amount of maintenance work and downtime when operating your equipment.

The GlobeCore Process can be used to purify oil before it is placed into your equipment and it can be used to purify and restore your used and contaminated oils and fluids.  GlobeCore equipment is flexible, versatile, reliable, and extremely cost effective.  GlobeCore adds Value to your maintenance program.

Hydraulic Oil Purification and Filtration Service

Tierra Fuller

During the process of manufacturing hydraulic oils, certain important production regulations are observed.  Before the oil is shipped to the client, the oil’s quality and purity is guaranteed and it should meet or exceed international standards.  When the oil is in transit from the manufacturer to the customer however, it is impossible to avoid some contamination of the oil.  During storage and transit, the fluid can and will accumulate insoluble solid particles, water, and air.  During the oil’s service life, the oil’s performance characteristics will further degrade.  The oil begins to oxidize and it loses its ability to perform its intended job of lubricating, insulating, and transferring heat.

Your hydraulic equipment’s built-in, or stock filtration system is usually quite limited.  And, the cost of adding an optional, or aftermarket, separate filter system can be unreasonably high.  On the other hand, timely filtration of hydraulic oil can help save on the cost of total oil replacement and disposal, as well as extend the service life of your hydraulic equipment.  It is therefore, important to ensure that the hydraulic oil is free from all forms of contamination prior to being placed into service in your hydraulic equipment.

Many years ago, a business required the assistance of skilled experts, additional training and the added expense of procuring several different types oil purification equipment in order to properly maintain their hydraulic equipment.  Today, that situation has changed.  Now there are less expensive and less labor intensive alternatives to hydraulic equipment maintenance.

Here at GlobeCore, our specialists are quite experienced in the development of hydraulic oil purification and filtration systems as well as systems for the purification of heavy duty industrial oils.

GlobeCore has has developed a line of equipment for the regeneration and purification of hydraulic oil.  This line of equipment leads the industry and is quite versatile and works on a wide range of industrial oils and fluids.  One of the most important aspects of an oil purification system is the pre-treatment of the oil to remove the bulk of free water and solids just before beginning the regeneration the process.

GlobeCore purification and regeneration units therefore, are equipped with drying, degassing and multistage filtration systems.  Before the hydraulic oils enter the adsorbent columns for lightening and regeneration, the oil is subjected to high vacuum to remove gas and water and is filtered for removal of particulate matter.  Sorbents are used in the finishing stages of the process and successfully trap the remaining contaminants and remove them from the oil.  This is known as the unique “GlobeCore Process” and it is the most advanced and most cost effective oil purification and regeneration system in the world today.

GlobeCore’s line of UVR plants purify and lighten used oil that has become dark.  It also removes sulfur and hydrogen-sulfuric compounds and easily purifies gas condensate by removing resins and other contaminants.  After the purification cycle is complete, the hydraulic oil is restored and its performance characteristics are like new.

Testing of the purified and/or regenerated oil product shows that regenerated and lightened hydraulic oil meets the highest purity and quality standards.  After the GlobeCore Process,  the oil is much more effective while performing in your industrial equipment.   The process significantly increases your profits, not only by saving on expenses, but also for allowing your hydraulic equipment to operate at full capacity because of the purified high quality oil.

The Problem

Disposal of waste oil is becoming less and less common.  According to the latest expert conclusions, a large amount of waste oil products are constantly being generated in many industrial applications.  This rise in industrial waste oil has led to increases in handling and disposal costs and fines for violations of environmental regulations.

The Solution

GlobeCore offers an excellent solution to the problem.  The GlobeCore Process is now available for the complete restoration of used oil used in commercial applications.  The customer will no longer have to  pay for oil disposal, oil handling and for environmental licenses.  Instead, the customer can now reuse the what used to be a waste product.  A unique oil purification and regeneration process is used in a wide range of GlobeCore products.  The GlobeCore Process is environmentally sound because it does not cause the emission of unwanted gases, liquids and solid materials into the environment.  The use of the GlobeCore Process  facilitates up to a 95% conversion rate and that equates to a tremendous saving for your company in time, labor, oil and money.

GlobeCore has a line of equipment intended for the purification and regeneration of used industrial oil by removing solid particles, water, and other contaminates.  The process produces oil color improvement due to the removal of oil aging products, unwanted additives and finely dispersed asphaltenes.  The GlobeCore machines are quite simple and easy to operate.  They do not require complex adjustments and enjoy the competitive advantage of high mobility and the use of special self-reactivating sorbents for the regeneration of fluids.

Up to 90% of tar, asphaltenes, carbenes and carboids are removed from the used oil in the process of purification with mild effect on the oil’s additives.   Various solid particles and water are removed entirely with complete restoration of the oil to it’s original specification and color.

Complete GlobeCore plants may be used for the filtration and adsorption process of various types of oils, including hydraulic fluids and industrial oils.  The GlobeCore systems does not require readjustment for various oils.  They also do not require filter replacements since the regeneration and adsorption elements automatically reactivate themselves after each cycle of oil restoration/regeneration has been completed.

The uniqueness and affordability of the GlobeCore Process units makes them an excellent and cost effective investment for your company.

The laws of hydraulic oil purification

Tierra Fuller, , , , ,

Oils and other operating liquids, used as lubricants and coolants in various industrial equipment, are prone to degrade under the influence of elevated temperatures, pressures or flow. The functionality of oils depends on viscosity, oxidation stability and purity, lubrication capabilities, corrosion and emulsification. The difference of hydraulic oils from other oils is the relatively higher viscosity of the oil for high pressure hydraulic actuators. High viscosity makes operation of equipment unsafe or impossible. On the other hand, to ensure efficient operation of the systems, oil viscosity must exceed 20 cSt. Otherwise the pumps will experience increased wear, causing rapid loss of efficiency.
