Nu-calgon 4300-30 Rx11-flush System Flush Liquid 19.5 Oz Can

Product Description

The Nu-Calgon 4300-30 Rx11-flush System Flush Liquid is a professional-grade refrigerant system flushing solution designed for HVAC technicians and refrigeration service professionals. This 19.5 oz aerosol can delivers a clear, fast-acting liquid flush that clears contamination, oil residue, and debris from refrigerant lines, coils, heat exchangers, and other system components. Proper system flushing is a critical step in any refrigerant retrofit, compressor replacement, or burnout cleanup. When a compressor fails — especially due to an electrical burnout — acids, carbon deposits, and degraded oil spread throughout the refrigerant circuit. Leaving those contaminants behind leads to repeat failures and shortened system life. Rx11-flush is formulated to remove those harmful residues before a new compressor or refrigerant charge is introduced. The liquid composition includes 60 to 100 percent (E)-1,2-Dichloroethene as the primary flushing agent, along with Decafluoro-Pentane, Pentafluorobutane, and Dimethyl Carbonate. This blend provides strong solvency power while remaining compatible with common refrigerant system materials. The low boiling point of 105.8 degrees Fahrenheit allows the flush liquid to vaporize and exit the system quickly after the flushing process is complete, reducing the risk of flush residue contaminating the new refrigerant charge. HVAC technicians use Rx11-flush during system changeouts, refrigerant conversions, and post-burnout cleanup procedures. It works on split systems, package units, commercial refrigeration equipment, and chillers. The product ships in a standard aerosol can for easy handling and controlled application on the job site. Using a dedicated system flush like the Nu-Calgon 4300-30 helps technicians meet manufacturer requirements for system cleanliness and supports longer equipment service life after repairs.
