RS-70 (R453A) is a non-flammable drop-in replacement for R22 which has been designed to have the lowest possible Global Warming Potential (GWP) consistent with high thermodynamic performance, with a similar cooling capacity and Coefficient of Performance (COP) of R22.
Consequently, RS-70 can be used to replace R22 in both air conditioning and refrigeration applications across the temperature range where R22 is commonly used.
RS-70 is compatible both with the traditional mineral and alkylbenzene oils, as well as the polyol ester lubricants – so that there’s no need to change the existing lubricant in the system when retrofitting to R22.
With its high technical performance, compatibility with all lubricants and low GWP, RS-70 is an excellent choice to replace R22 as the complete prohibition of this refrigerant approaches as mandated under the Montreal Protocol, the F Gas regulation in the European Union and other country-based restrictions.
The GWP of RS-70 is lower than all other drop-in replacements for R22 available on the market including R438A, R417A, R422B, R422D, R417B, and others; it is also lower than R427A, R407A, R407F & R421A. However, this has not been achieved by sacrificing performance, since RS-70 is similar to R22 in terms of cooling capacity, COP, mass flow, compression ratio and discharge pressure while having a lower discharge temperature.
