RS-53 (R470A) is a direct drop-in replacement for R410A with a Global Warming Potential (GWP) less than half that of R410A.

It has comparable thermodynamic performance, energy efficiency and cooling capacity to R410A, and is compatible with materials and lubricants typically used in R410A equipment, making retrofitting easy and low-cost.

RS-53 (R470A) is non-flammable, which sets it apart from other alternatives such as R32 – a flammable refrigerant suitable for new systems but not existing ones – making it an excellent solution for those seeking a replacement for hydrofluorocarbons.

In addition, RS-53 (R470A) contains low-toxicity components known to be extremely chemically stable in air conditioning systems.

Benefits

  • Replaces R410A in air conditioning and refrigeration applications
  • A Global Warming Potential (GWP) of 909
  • Similar energy efficiency to R410A
  • Close match for R410A in cooling capacity
  • Similar discharge pressure to R410A
  • Compatible with lubricants commonly used with R410A
  • Similar flow rate to R410A
  • No changes to hardware required during retrofitting
  • Zero Ozone Depletion Potential
  • Non-flammable & low toxicity

Variants

  • 50kg (01010014)

The retrofit procedure for replacing R410A with RS-53 is as follows:

(1) Ensure the right equipment is available, eg recovery unit and cylinders, container for recovered lubricant, vacuum pump, weighing scales, replacement drier etc.
(2) Record baseline data to establish the normal operating conditions for the equipment.
(3) Weigh recovered amount of R410A to determine amount of RS-53 to add (see 5 below.)
(4) Replace the filter/drier.
(5) Having evacuated the system, initially liquid charge the unit with approximately 10% less RS-53 than the weight of R410A specified by the manufacturer.
(6) Switch on the unit and monitor any sight glasses fitted, the suction line pressure and temperature, and the discharge temperature.
(7) Check system thoroughly for leaks.
(8) Clearly label system RS-53.
