RS Series of drop-in replacements

Refrigerants to replace R22 and R404A, R507 and all 400 series gases.. 

The RS Series of refrigerants are drop-in, low global warming potential, non-ozone depleting and non-flammable. Excluding RS-50, all can be used both with traditional lubricants (eg mineral and alkyl benzene oils) and the new synthetic lubricants such as polyol esters. They provide a simple and low-cost method of switching away from CFCs, R22 and R404A, R507 and all 400 series gases. .

RS Series gases offer a solution to operators who are looking to ensure F-Gas compliance for existing refrigeration and air conditioning systems until 2030. Call us on +44 (0) 1244 504 500 for advice.

RS-24 (R407A)

Zero ODP drop-in replacement for R12 No oil change required, compatible with all lubricants. The easy and long-term solution to replacing R12.

   

RS-44 (R424A)

Predominantly air conditioning applications. Medium to high temperatures. Evaporating down to -100˚C. Suitable in fixed orifice systems & also with an expansion device. Low discharge pressure which makes RS-44 particularly suitable for high ambient temperatures.
   

RS-45 (R434A)

Primarily for refrigeration applications at medium to low temperatures down to -35˚C. Proven suitable replacement for R22 in flooded systems with low temperature glide.

   

RS-50 (R442A)

Low GWP Drop-in replacement for R404A and R507 with higher efficiency and capacity. Can also replace R22 at low temperature with change of lubricant to POE.

   

RS-52 (R428A)

Drop-in replacement for the range of ozone depleting blends including R402A, R404B, R403B, R408A and R411B.

   

RS-53 (R470A)

A non-flammable, low Global Warming Potential (GWP) drop-in replacement for R410A. RS-53 is the only R410A replacement refrigerant on the market that has been awarded an A1 ASHRAE classification. 

 

RS-70 (R453A)

Suitable for use in both air conditioning & refrigeration applications. Suitable for use in systems with a capillary or TXV with similar mass flow to R22. Lowest GWP drop-in replacement for R22 on the market.

 

Gas Cylinders

Cylinder weights available for all gases: 13kg disposable, 10kg/50kg refillable.
