Is Fuller’s earth needed?

For Class III oils that are service aged, Fuller’s earth treatment will be required.  Color number, Acid Neutralization Number and Interfacial Tension are good indicators of the condition of Class III oils.  Fuller’s earth processing systems are available in a variety of configurations sized to the flow rate of the vacuum oil purifier.  They can be incorporated into the purifier system itself or provided as a separate module to be connected and used only when needed.

Fuller’s earth

Fuller’s earth can be used to decolorize and neutralize any petroleum oil, especially dielectric insulating oils.  It also excels in neutralizing traces of strong inorganic acids.  Due to the relatively large pores found in Fuller’s earth, it is well adapted to the removal of high molecular weight sulfonates, resins and asphaltines.

Transformer oil will discolor as oxidation takes place.  Color, by itself, is not a reliable test in evaluating the condition of the oil for further use.  It is however, a strong indication that something is happening within the transformer that requires investigation.  Once transformer oil changes from the yellow color range into the orange and red color range, it has degraded to the point where the vital parts of the transformer are being seriously affected.

As the color of the oil changes, sludge is forming in solution with the oil due to oxidation.  This causes a drop in interfacial tension and an increase in the acid (neutralization) number.  When transformer oil deteriorates to the red color ranges, deposited sludge continues to oxidize and harden, blocking vents and insulating cooling fins, causing higher operating temperatures.  Solid Insulation shrinkage may take place, and premature failure is likely.


GlobeCore provides the service of Fuller’s earth filling and replacing in your equipment.  Care must be taken not to expose the Fuller’s earth to humid air or moisture.  This causes the clay to loosen its granular structure and can turn it to plain mud.  It is recommended that the clay be purchased in vapor-insulated bags to keep it dry.  For best performance and flow rate, oil should be supplied to the filters at a temperature of between 160 to 180 degrees F and a supply pressure capability of up to 80lbs. psi.

Leakage oil reclamation

Cost effective green solutions for facility oil reclamation

Total Lubrication Management provides efficient, environmentally friendly methods of reclaiming valuable lubricants on-site that minimize waste oil.  You receive bottom-line benefits from our abilities to:

  • Reduce new lubricant and oil purchases;
  • Support sustainability through oil conservation;
  • Decrease disposal liability;
  • Diminish environmental exposure and liability; and
  • Guarantee your oil cleanliness specifications are met

Environmental benefits

Total Lubrication Management stays ahead of the environmental curve through continuous review of EPA and safety regulations.  We make you aware of the latest updates as they apply to your specific operation.  And, we carry extensive liability insurance.  Even when it’s not practical or possible to slow down critical systems that need repair until the next scheduled outage, Total Lubrication Management can offer you a short or long-term rental of purification equipment to help you continue operating and address contamination issues without shutting down your operations.

The reclamation process

Sometimes it’s impractical to repair or control oil leaks if continued production is reliant on the subject equipment.  The Total Lubrication Management method of collecting and segregating leakage oil enhances your ability to restore the lubricant for continued use.  On-site waste oil is collected in dedicated storage via segregated waste streams, then purified by our experienced Total Lubrication Management technicians.  We work with your facility personnel to:

  • Identify high-lubricant use areas for reclamation;
  • Establish proper segregation, handling practices and purification using a variety of methods:;
    • First and second stage filtration
    • Centrifugal separation
    • Vacuum dehydration
    • Polishing filtration
    • On-site analysis
  • Create lubrication cleanliness/condition guidelines to ensure suitability for continued use;
  • Complete and verify that guidelines are met to your oil cleanliness specifications; and
  • Document the performance benefits.

Fuel oil filtration services

Process Details

Step 1:

Determine OEM Specifications for Fuel Cleanliness

Step 2:

On-site assessment of current Fuel Distribution

  1. Fuel analysis for cleanliness, water and bacteria
  2. Core samples of main storage tanks

Step 3:

Develop Comprehensive Blueprint

  1. Recommended actions based on test results may include
  2. Purification of current fuel to remove solids and water;
  3. Treatment of bacteria; and

iii. Storage tank preventive maintenance to remove accumulated contamination

  1. Initial Fill from delivery vehicle to storage tank;
  2. Distribution from storage tank to Mobile Fuel Trucks; and
  3. Distribution from Mobile Fuel Trucks to point of use

Step 4: Perform analysis and document Fuel Cleanliness ** Option for permanent installation of field equipment

In order to meet new air emission regulations, OEM’s have redesigned injector systems that require cleaner fuel to operate.  Utilizing unfiltered fuel can lead to injector failures resulting in poor performance, unplanned downtime, exceeding emission standards and high repair costs.

To make sure your equipment operates at peak performance, the filtration experts at Globecore can provide a comprehensive analysis of your fuel distribution – from transport delivery to use.  We will investigate the current condition of the fuel in the storage tanks and recommend corrective action if required.  We will develop a comprehensive filtration blueprint for fuel distribution throughout your facility that continuously meets or exceeds OEM requirements. As a result, you can operate your equipment with confidence.  On-site Inspection Provided by Filtration Experts Knowledgeable Globecore staff work with plant personnel to: *Recommend the best filtration for your application and establish fuel cleanliness specifications based on OEM recommendations.  *Present and distribute completed documentation to site management Globecore’s technicians arrive on-site to:

*Perform corrective action to current fuel/storage tanks if required;

*Coordinate installation of filtration units at various points throughout the fuel distribution system;

*Gather key baseline data for documentation; and

*Provide Service Summary that details the steps completed and any additional recommendations in ensuring long-term performance.

Globecore Filters provide these benefits:

*Continuously meet emission standards in properly maintained diesel equipment;

*Reduction in OEM filter usage and related costs;

*Reduction in repair expenses due to reduced wear and longer component life;

*Increased availability of manpower due to improved maintenance repair cycles; and

*Optimized equipment reliability.

Environmental Health and Safety:

Globecore routinely reviews EPA and safety regulations, including the latest updates as they apply to your specific operations.  In addition, Globecore carries extensive liability insurance.
