Cold-Plus is a additive that you can add to any
system and is compatible with all refrigerants.
The purpose of Cold-Plus is to increase the
efficiency of air conditioning and refrigeration
systems by:
Eliminating oil fouling and improving heat exchange.
Reducing amp draw, compressor temperature, and decibel level.
Eliminating amp spike on compressor start up.
Increase refrigerant flow 5-8 percent
