Varnasolv FG

Varnasolv FG

Food Grade Equipment Varnish Cleaner

Varnasolv FG is a lubrication system cleaner designed to remove varnish and sludge in equipment used in the food & beverage industry.  The use of petroleum lubricants 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 FG is built for food grade applications and is NSF HX-1 registered. This eliminates the need to run the compressor unloaded when flushing a unit in a food processing facility. Varnasolv FG reduces the problems caused by varnish and carbon. Using Varnasolv FG eliminates the need for disassembling the equipment for cleaning.

 Varnasolv FG should be added to the existing lubricant at a 10% concentration to remove and suspend varnish while the equipment is running. For maximum benefit, use Varnasolv FG before each lubricant change.

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

How to use Varnasolv FG:
Cleaning Hydrocarbon Deposits from Equipment
Initial Clean-Out Method
Add one gallon of Varnasolv FG concentrate to each ten gallons of oil in the unit, first draining enough oil to allow adding the Varnasolv FG. 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.

NSF ISO 21469

ISO 21469 specifies hygiene requirements for the formulation, manufacture, use and handling of lubricants, which may come into contact with products during manufacturing or processing. The international standard applies to lubricants intended for use in food production, as well as cosmetic, pharmaceutical and animal feed industries. NSF ISO 21469 Certification by an independent, third party provides Summit with a means to obtain international acceptance for their products.

A product that is NSF H1 Registered is approved for use where there might be incidental food contact. The categorization of “lubricant for incidental food contact” represents the use of a lubricant which, as a consequence of general use of the machinery or equipment to which it is applied, may result in the contact of that substance with food. All of Summit’s Food Grade products are H1 Registered.
