How to Choose the Best Oil Filtration System?

The choice of a product depends on various external factors.  Price, quality, performance, and reliability are just some the considerations when choosing a product.  The choice of industrial equipment also depends many of the same factors.

In choosing oil processing equipment, you will find that there are many different types of processing units intended for purification of different petroleum based oils  and fluids.

There are a large number of manufacturing companies specializing in oil processing systems. These systems include a wide range of equipment used to process different lubricants, hydraulic and turbine oils, and complex systems for oil regeneration.

The purchase of equipment for the filtration and purification of used oils is justified through the saving of money and resources.  Additionally, this equipment greatly helps in reducing problems with equipment failures and downtime, as well as reducing environmentally harmful waste oil products.  Overall, these modern machines greatly increase the service life of industrial equipment.

When choosing the right processing equipment for your business, strict attention should be paid to the technical specifications of the filters that will be used by the processing equipment:

  1. The physical size of the oil filter. This key component of the purification system must be small enough to save space and weight, but have high filtration performance in both volume and filter fineness;
  2. Filter Test Results.  Oil filters can be monitored in various ways, but one of the most common methods is the beta-factor test.  The beta factor is calculated by dividing the number of the larger particles trapped in the filter medium by the number of particles of the same size downstream of the filter.  For example, if the beta ratio is 10:1, it means that for every ten (10) particles that enter the filter, only one (1)passes through the filter without being trapped in the filter medium;
  3. Pore ​​size of the filter medium; and
  4. Performance and rate  flow.

According to studies conducted by General Motors, and published by the Society of Automotive Engineers (SAE), it was determined that the service life of an engine can be increased eight times by using five (5) micron filter mediums instead of the standard 40mm filter medium found in most massed produced automotive oil filters.

This means that the steady improvement of oil filtration systems will continue as the cost of new equipment rises and consumers demand better equipment with longer service lives.  There is an old saying that contends that oil does not wear out, it only becomes dirty.  In any case, keeping oil clean and free from contaminants and moisture will greatly extend the service life of your electric power equipment and hydraulic systems.

The traditional oil change therefore, is no longer necessary.  The high tech equipment available from GlobeCore can keep your insulating oils and hydraulic fluids in new like condition indefinitely.  Oil Processing units from  GlobeCore remove soot and sludge, dirt, moisture and dissolved gases.

If however, you decide to invest in oil processing equipment, it is worth taking the time to carefully consider your needs.  You will soon learn that not all systems for filtering oil are created equal.  Sometimes, bright brochures are specifically designed to confuse the customer.  As the consumer and business manager, you should make sure that filtration and processing equipment has passed all the necessary tests and has verified results of performance.  Here at GobeCore, we work with our customers to determine the best equipment that meets the needs of our customers.  GlobeCore has a very large and diverse line of oil processing equipment.  We work very closely with our customers so you get the best and most cost effective equipment to compliment the needs of your business.

Fuller’s Earth From Clay; A Type of Ceramic Art

Clay; More than Just Art!

It has been a long time since man began to use clay for folk art and the creation of art objects.  All possible images that were originated in the minds of ancient people and continue to appear in modern enlightened minds, can be turned into reality and get their shape with the help of waxy clay.  But, imagination and centuries of experience teaches us to have a broader outlook of the world.  It is safe to say therefore, Clay is not just for art anymore!

At one time, clay was a material generally used only for crockery, amphorae and sculptures.  Today however, clay is quite widely used in cosmetology, medicine, household chemicals, industry and a whole host of other uses.

It is no longer a secret that the chemical composition of different elements, that originated from the Earth’s interior, has had different affects on their characteristics and abilities.  As for clay, its “recipe” is also quite different.  Thus, there are many different ways that clay can be used in our modern world.

Clay and Industrial Uses

Industrial enterprises in various fields are the main consumers of all inventions and innovations connected with chemical and technological transformations.  Clay has many components and one of them is known as “Fuller’s Earth.”  In the scientific community, it is known as an “adsorbent.”  This earthy material mainly consists of a clay mineral that is considered not too waxy.  Fuller’s Earth therefore, is used as an adsorbent material that filters and purifies by attracting and holding contaminates on its outer molecular structure.

The Fuller’s Earth adsorbent material got its name from the original application in which it was used for the removal of oil from textile materials.  Later, Fuller’s Earth became very popular for the filtration of vegetable and mineral oils.  Its versatility and flexibility gave the the Fuller’s Earth adsorbent material many advantages in the oil purification industry.

“Oil Regeneration” machines, that utilize the Fuller’s Earth adsorbent materials, have become the most efficient and cost effective machines for the recovery of waste industrial oils available in the industry today.

One “Fuller’s Earth” regeneration cycle fully restores the oil back to its original characteristics.  After the Fuller’s Earth has regenerated and restored the used oil back to like new condition, it can then be reactivated and ready to purify oil again and again.  Thus, these machines definitely can be classified as modern industrial “works of art.”  So, clay continues to serve man in both form and now function.

GlobeCore now offers Oil Regeneration equipment featuring the clay based Fuller’s Earth Adsorbent material that is the best and most cost effective oil purification method in the industry today.  The GlobeCore Process not only purifies and regenerates oil and hydraulic fluids utilizing Fuller’s Earth, it reuses the adsorbent materials based upon an automatic adsorbent reactivation system built in to the regeneration equipment.  The GlobeCore machines can continuously purify oil without having to change and dispose of the adsorbent materials.  This industry leading breakthrough makes the process of regenerating oil products clean, efficient, and most of all, very cost effective.  The Environment Loves the GlobeCore Process and you will too!  GlobeCore, using Clay for a cleaner environment.

Tests and Trials: Sport, Art or Industry? Analysis of Transformer Oil Purification

The correct use of oil guarantees the reliability of industrial equipment and the prevention of equipment failures.  Transformer oil is a dielectric insulator and a coolant.  It also serves as an arc extinguisher preventing shorts and internal fires.

Transformer oil parameters degrade over time as the oil ages.  Oil oxidation is mostly caused by external elements such as water, air, acids and heat.  Aging of oil is best indicated by its acidity level, water content, and sediment and sludge formation.

Sludge accumulates in the solid insulation, the core, in cooling channels and other places inside the transformer.  Sludge is a dangerous enemy that degrades the oil’s cooling and heat transfer capabilities and damages the solid insulation causing it to disintegrate.  A short-circuit in the transformer windings becomes a much higher possibility due to oil degradation and sludge build up.

The acid level of the oil, as measured by the “Acid Number is the main indication of oil degradation and oil aging.  Acidity is measured by special litmus paper that changes color when subjected to contaminants.  Acids can damage cellulose insulation and metal parts of the transformer.  Acid levels can also measured through an oil analysis program.

The Acid number, as the main indication of transformer oil quality, is the amount of grams of KOH required to neutralize all free acids in one gram of oil.  The Acid number indicates how much the oil has aged and whether it should be regenerated using the GlobeCore Process.  Once the Acid number reaches 0.08 and higher, the transformer oil becomes aggressive and begins to destroy the solid insulation of the transformer.  The Acid number therefore, is the best indicator of when to service your transformer before irreversible damage is done to the insulating paper.

Besides chemical parameters, transformer oil must comply with certain physical and electric parameters.  Degradation of these important oil qualities may indicate problems inside your power equipment.

For instance, the oil’s flashpoint must be high enough to ensure fire safety in overload conditions and high temperature increases inside the transformer.

Dielectric strength of transformer oil is important for the prevention of breakthroughs in the transformer insulation.  This parameter is measured regularly by high voltage breakthrough indicators.  Transformer oil is tested six times with 10 minute intervals between each test.  The average of six tests is used to determine the dielectric strength.  If the results are unsatisfactory, another sample is tested and a decision on the course of action is made.

Fresh or used transformer oil must be tested before being placed into the transformer.  Some parameters tested are particulate matter content, general oxidation stability, transparency, dissipation factor, flash and setting points, viscosity, acidity and water content.

These measures are designed to identify and resolve problems before the they can cause a transformer failure shutting down the transformer.

Transformer oil is purified of contaminants, acids and gases in purification and regeneration equipment specifically designed for transformer maintenance.  Complete preventive maintenance systems, such as the GlobeCore CMM-R line of equipment will reduce costs and downtime while increasing operating profits.

Why do we use dry and clean transformer oil? Importance of transformer oil purification.

Reliable operation of transformers is dependent on the condition of internal insulation. Transformers are insulated by liquid (oil) and solid (cellulose) insulation. Dielectric oil accounts for about 80% of the system’s dielectric strength. It is a very good dielectric, and it permeates cellulose insulation further increasing the dielectric strength of winding insulation material. Viscosity characterizes the oil’s cooling ability.

The oil must be protected from oxidation, avoiding overheating and contact with contaminants, since most of transformer failures are due to insulation failures.

Cellulose materials are the weak link of transformer insulation. Contamination of internal insulation by things like water, dissolved gas and solid particles cause degradation of insulation materials. Cellulose insulation quickly accumulates contaminants.

One of the main factors of transformer oil and solid insulation degradation is water. It inevitably enters insulation systems. The result of its influence (along with other contaminants) is aging of oil and formation of various degradation products, sludge, acids etc.


When oil absorbs air and moisture, the aging process occurs even under light loads. Water in transformer oil consists of free water, water solved in oil degradation products and chemically bound water. It is impossible to extract all water from solid insulation.

Transformer oil can accept more water at elevated temperatures. When oil is again cooled, this water precipitates form the oil and enters solid insulation. Cellulose insulation absorbs water form the oil and retains it. Acids resulting from oil aging have a negative effect on cellulose and metals and form soapy metal, aldehyde, alcohol etc which form acidic sediment on solid insulation, internal surfaces of the transformer, breathing system, cooling system etc.

While water and heat are damaging to solid insulation, correct maintenance of cooling and insulation system can extend their lifetime to 60 years. Equipment formerly used for transformer oil drying only is quite obsolete. At present oil can be restored entirely. The parameters of regenerated (reclaimed) oil are extremely close to those of new oil. Service life of well maintained transformer oil is virtually unlimited.

The modern comprehensive transformer oil purification plants include degassing, drying and lightening, as well as filtration and regeneration. The resulting regenerated product is as good as new. Therefore, new oil purchase costs are reduced. The cost of purchased and regenerated oil is recovered.

The cost of regeneration of used transformer oil is always considered in relation to the high cost of purchasing new resource and possible downtime costs. It is quite obvious that owners of complete transformer oil regeneration plants are always in advantage.
