Description
The Nu-Calgon 4300-08 Rx11-Flush Starter Kit provides HVAC/R technicians with everything needed to begin flushing refrigerant systems quickly and effectively. Rx11-Flush is a fast-evaporating, non-ozone-depleting flush solvent specifically formulated to remove mineral oil, alkylbenzene oil, POE oil, contaminants, moisture, and system debris from refrigerant lines, coils, and components during retrofits, changeouts, or after compressor burnouts.
This starter kit is ideal for technicians transitioning systems to new refrigerants or restoring contaminated systems to peak operating condition. The flush solvent evaporates cleanly, leaving no residue behind, so there is no need to recover the flushing agent before recharging the system.
