Refrigerant Solutions Ltd (RSL) introduces RS-70 a new refrigerant to the market.

RS-70 is a new 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 having a similar cooling capacity and Coefficient of Performance (COP) as 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, and also the polyol ester lubricants so that there is 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 end of R22 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. The GWP of RS-70 is also lower than R427A, R407A, R407F and 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. Accordingly, RS-70 is an excellent choice to replace R22 in the majority of applications where R22 is found.
