r407c

R407C

A colourless, flammable gas at atmospheric pressure with a slight ethereal odour.Provides efficient cleaning and have a surround- protection model. Widely used in air conditioning system.


Uses and Features:

  • Large commercial refrigerated air conditioning systems.
  • A replacement for HCFC-22.

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.
