MIXED REFRIGERANT R404A

Introductions

R404A is an HFC blend that is widely used in low and medium temperature refrigeration applications, such as those used in commercial refrigeration. Whilst it has become the widely accepted alternative to CFC R502, R404A is coming under greater scrutiny due to its high Global Warming Potential, leading to an increased focus on lower GWP alternatives such as R407A, R407F and R442A.

Applications

R404A is suitable for use in new equipment as a replacement for older R502 applications. It can also be used to retrofit some old R22 systems with an oil change.

  • Commercial Refrigeration:
    • Plug- Ins & Vending Machines
  • Industrial Refrigeration
  • Transportation Refrigeration

Handling & Storage

R404A refrigerant cylinder is a pressurized container, which should be stored away from fire, heat source, avoid direct sunshine, and usually stored in a cool, dry and ventilated warehouse. When handling, it should be lightly loaded and unloaded to prevent damage to cylinders and valve accessories.
