R134A

R134A

A colourless, non-flammable gas at atmospheric pressure with a slight ethereal odour. Replaces R-12 in refrigeration and air conditioning system. Used in new medium and high temperature stationary commercial refrigeration, chiller, and other cooling appliances.


Uses and features:

  • Wide use in household and commercial refrigeration, and automotive air-conditioning. Properties make R134a suitable for use in medium temperature food cabinets, water chillers and fountains, heat pumps and dehumidifiers.
  • Increasing use as a replacement for CFC-12
  • Blowing agent for various foams.
  • Propellant for aerosol pharmaceuticals, lacquers, deodourants, perfumes, mousses, air fresheners, insecticides, cleaning and other household products.

Material Compatibility:

Most common materials are suitable for use under normal conditions in a dry system. At high temperatures, use stainless steel or Inconel to resist corrosive breakdown products. Avoid using alloys with more than 2% magnesium(i.e. some aluminium alloys) especially when moisture is present. May react violently with sodium, potassium, barium and other alkali or alkaline earth metals. Flexible hoses or gaskets should not contain natural rubber as rapid withdrawals of gas/liquid can extract compounding ingredients and it also suffers from excessive swelling.
