ALV Varnish Remover

Benefits

• Removes varnish and carbon deposits caused by overextended lubricants.
• Reduces maintenance cost by alleviating the problems associated with varnish and carbon.
• Eliminates the need for compressor disassembly for cleaning.
• Proprietary Formula:
  - Solvent-alcohol
  - Nonionic surfactant
  - Synthetic base fluid
• ( 77 cSt @ 40ºC ) Viscosity approximates most rotary screw compressor fluids.
• Freudenberg Case Study: Energy savings of 9.5% by cleaning with
  ALV Varnish and switching to Simmons Synthetic oils.
• ALV Varnish can be used for cleaning Heat Transfer systems with
  tempeatures up to 400°F. Also, it can be used for cleaning high
  temperature chains.

Recommended applications

Rotary screw air, gas and refrigeration compressors, centrifugal compressors, gearboxes, diesel & natural gas engines, hydraulic systems
and heat transfer systems and gas turbines systems.

Replacement for Atlas Copco GA-OK, Leroi Comp Cleaner 11, Palatek UC Ultraclean, Pennzoil Therma-Solve, Quincy Quin-Syn Flushing oil.

Materials Compatibility

ALV Varnish remover is compatible with all lubricating base fluids with the exception of silicone-based lubricants.

HOW TO USE ALV VARNISH TO CLEAN ROTARY
VANE & SCREW-TYPE COMPRESSORS

INITIAL CLEAN-OUT METHOD

Add one gallon of ALV Varnish remover concentrate to each ten gallons of compressor oil in the unit, first draining enough oil to allow adding the ALV Varnish remover. Continue to run the compressor for 40 to 60 hours, allowing the treated oil to disperse and suspend the varnish. To avoid redepositing the suspended contaminants, drain the oil while hot and replace filters. Refill with fresh AIP synthetic Oil.

COMPRESSOR CLEANING MADE EASY

With the special cleaning fluid ALV Varnish remover you can clean your rotary screw gas compressor or equipment during operation - fast and effectively, without machine stoppage.
ALV Varnish remover is a highly effective concentrate: It is added to the oil fill at a concentration of 10 % before the oil change. While the equipment is still operating, it releases contaminants and deposits from the walls,
which remain suspended in the oil. When the old oil is then drained for the changeover, these particles are removed.

This method is much more effective than simply flushing the compressor or equipment with a normal lubricating oil. Most mineral oils have very poor cleaning characteristics to remove varnish and other deposits from the walls.
However, if these de-posits are likely to affect the new oil fill or cause additional wear, thorough cleaning is indispensable.

You have the option of using ALV Varnish remover, or else you may resort to disassembling your compressor completely to clean all its parts manually. You can imagine which solution we will suggest to increase the efficiency and availability of your compressor.

Caution!

When changing over to special oils, the compressor as well as all major oil lines and filters should be thoroughly cleaned. Otherwise residues of the old oil may affect the quality of the newly filled AIP
oil.

REGULAR USED-OIL ANALYSES.

If you wish to accurately time oil maintenance stoppage and avoid additional downtime, you should have the oil in use analyzed periodically. As the gas composition in a compressor is never the same, any prediction
of compressor oil life is a rough estimate. Oils may age faster or live longer than expected. It is therefore advisable to regularly analyze the compressor oil being used.

Depending on the types of gases, operating conditions and compressor runtime, we will define sampling intervals together with you. We will provide you with standardized sample bottles, which you fill and send to
our lab at the specified intervals. A few days later, you will receive a comprehensive lab report informing you about the conditions of your oil and any steps to be taken.

This measure will help to prevent machine downtime, reduce maintenance costs and increase compressor availability.
