Be the first to review this product

RS-50 (R442a) has demonstrated extreme energy saving in case after case. At 1888 Global Warming Potential (GWP), RS-50 is less than one half of R404a and R507. RS-50 is a high efficiency drop-in replacement for R404a and R507 refrigerants. RS-50 is compatible with all materials commonly used in refrigeration systems previously charged with R404a, R507a and R22. lt is recommended to check equipment manufacturer's retrofit literature and obtain recommendations from equipment manufacturers with regard to materials' compatibility. RS-50 has higher COP and capacity than R404a &R507 and R22. Mass flow is equivalent to R22 and considerably lower than R404a & R507. It is Zero Ozone Depleting, non-flammable and low toxicity. Environmental Data None of the components of RS-50 contains chlorine so that it has no ability to deplete the ozone layer. As with all hydrofluorocarbons (HFCs), RS-50 does have a direct global warming potential (GWP), but at just around 1800 GWP it is one of the lowest HFC's available. Tests have shown that RS-50 has a higher Coefficient of Performance (COP) than R404a & R507a in a range of applications including commercial refrigeration systems. ComStar International Inc., a chemical company with more than 47 years of experience, it is one of only a companies in the world that have "DROP-IN" direct replacement HFC refrigerants for R12, R22, R502 and R404 systems.
