R123

R123:

A colourless, non-flammable liquid at atmospheric pressure with a slight ethereal odour. Replaces R11 and provides efficient cooling and air conditioning system. This new gas has proven to have low ozone depletion effect. Applicable in low-pressure centrifugal chillers and new centrifugal equipment.


Uses and Features:

  • Refrigerant
  • Heat – Transfer fluid

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.
