Guidelines for Using R441A/HCR188C and Derivatives in Refrigeration and Motor Vehicle A/C Units
R441A/HCR188C is a hydrocarbon-based refrigerant that does not deplete our Earth's protective ozone layer as fluorocarbon refrigerants like R-12, R134A, and R1234YF and has no impact on the environment like global warming, and is non-toxic and PFAS-free.
Inhalation of chlorofluorocarbons and hydro chlorofluorocarbon (CFCs and HCFC) refrigerants can cause oxygen deprivation, with serious health consequences.
R441A/HCR188C was developed to replace the fluorocarbon refrigerants. R441A/HCR188C is compatible with proprietary seals, gaskets and most lubricants in existing refrigeration systems.
R441A/HCR188C, like any other hydrocarbon product, is flammable and must be used only by trained personnel and certified in the specific safe handling procedures for refrigerant gases. Fully trained and EPA-certified HVAC personnel following the specified precautions will find that HCR188C can be easily and safely charged into existing HVAC/MVAC systems.
Although R441A & R443A/HCR188C are flammable, with a limited charge amount used in a refrigerated or A/C system would lower the risk of an accident in a catastrophic leak.
Workplace safety is no accident. It does take an effort to learn and follow new safety procedures and to make them a part of every refrigerant retrofit job. The user alone has the responsibility to follow the R441A & R443A/HCR188C safe handling procedures to uphold the high safety standards of the HVAC/MVAC industry.
Guidelines for Using R443A/HCR188C and Derivatives in Household Air Conditioners & Heat Pumps
R443A can replace the R22/R32A in HVAC or heat pump systems.
