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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFormulated to remove oil residue, acids, and carbon deposits from refrigerant circuits after compressor failure or burnout\u003c\/li\u003e\n\u003cli\u003eLow boiling point of 105.8 degrees Fahrenheit allows flush liquid to vaporize and exit the system rapidly after application\u003c\/li\u003e\n\u003cli\u003eCompatible with a wide range of refrigerant system components and commonly used in retrofit and changeout procedures\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Nu-Calgon 4300-30 Rx11-flush System Flush Liquid gives HVAC and refrigeration technicians a reliable tool for cleaning contaminated refrigerant circuits before recharging or replacing components.
