Interior Refrigeration Coil. system Cleaner



ComStar’s CF-20 is an internal coil cleaner specifically formulated to break down and dissolve hardened carbon deposits after a compressor failure or burnout. CF-20 also removes acid deposits and water from a system's coils and lines.

CF-20 is CFC-free, biodegradable, non-flammable, non-chlorinated, low V.O.C. leaves no residue and will not contaminate oil or refrigerant. In addition, CFC has a phased evaporation rate. CF-20 is safer and easier to use than chlorinated and flammable solvents.

This unique product will clean the interior of coil lines in refrigeration or air conditioning systems after a compressor burnout and/or before a new compressor is installed. It can be used in refrigeration or air conditioning systems that utilize mineral, ester, PAG, or alky benzene type refrigeration oil and is compatible with CFC, HCFC, or HFC refrigerants. CF-20 can clean refrigerant recovery, recycling, and/or reclaim equipment as well as all refrigeration and air conditioning mechanical parts. It can be used to eliminate mineral oil residue from systems before changing over to synthetic oil. CF-20 dosage is approximately 1 gallon per ton, and for total system cleaning the system should be filled with CF-20 and circulated throughout the system using a pump.
