The use of petroleum lubricants, mainly automatic transmission fluid (ATF), in rotary screw compressors, rotary vane compressors and other high temperature equipment, results in varnish and carbon formation. The varnish and carbon deposited throughout the equipment can cause many serious operational problems, resulting in excessively high maintenance costs.

Varnasolv can help reduce the problems caused by varnish and carbon. Varnasolv should be added to the existing lubricant to remove and suspend varnish while the equipment is running.  Using Varnasolv eliminates the need for disassembling the equipment for cleaning. For maximum benefit, use Varnasolv before each lubricant change. Varnasolv is NSF Registered P1

Additional applications for Varnasolv include cleaning hydraulic systems, gearboxes, and high temperature chains. Varnasolv can also be used for cleaning Heat Transfer systems with temperatures up to 400°F. 

Varnasolv HV is blended to a higher viscosity for minimal dilution when used in gear box lubricants.

Add one gallon of Varnasolv concentrate to each ten gallons of oil in the unit, first draining enough oil to allow adding the Varnasolv.  Continue to run the equipment for 20 to 40 hours, allowing the treated oil to disperse and suspend the varnish. To avoid redepositing the suspended contaminants, drain the oil while warm and replace filters.  Refill with new oil.

Packing: Varnasolv is available in cases (six gallons), five gallon pails or 55 gallon drums.
