FULLERS EARTH SYSTEMS

DESCRIPTION:  Fullers Earth can be used to decolorize and neutralize any petroleum oil, especially electrical insulating oils. It excels in neutralizing traces of strong inorganic acid. Due to the relatively large pores in fullers earth, it is well adapted to the removal of high molecular weight sulfonates, resins, and asphaltines.

OXIDATION:  Transformer oil will discolor as oxidation of the oil takes place.  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.

OXIDATION PRODUCTS:  As the color of the oil changes, sludge is forming in solution with the insulating liquid due to oxidation.  This causes a drop in inter­facial tension and an increase in the acid (neutralization) number as well as a drift in power factor.  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.  Insulation shrinkage may take place, and prema­ture failure is possible. 

BENEFITS OF FULLERS EARTH TREATMENT:  Maintaining oil quality with a Baron USA ‘HV’ high vacuum fluid purification system helps increase oil life, improves equipment performance, reduces downtime and reduces oil disposal and replacement costs.  In conjunction with the dehydration, degasification and filtration provided by a Baron HV purifier, Baron ‘CL’ Fullers Earth systems are used to correct the additional challenges with oxidized dielectric liquids.

SIZES AND CONFIGURATIONS:

The BA-CL family of fullers earth systems are available in a variety of sizes and types including stationary and mobile.  They can be configured to pair with a Baron HV purifier or with pump and heaters to operate stand-alone.  Single bulk filter systems are available with earth capacities of 250, 500, 850, 1000, 2000 pounds – sized to suit any flow rate and usage need.

STANDARD COMPONENTS:  ASME designed Housing, Welded Pipe & Fittings, Vacuum Filling System and Hydraulic Dumping System.

PERFORMANCE:  Typical performance in a single pass through the BA-CL Fullers Earth system is as follows (transformer oil):

Neutralization Number:  reduction from 0.3 to 0.03 mg KOH/gm or less (D974)

Interfacial Tension:  ≤ 30 Dynes/Cm minimum (D1861)

Color:  0.5 maximum (D1500)

BaronUSA offers the above model numbers based upon capacity, flow rate, and configuration.
