R404a Refrigerant Gas Supplier - Refrigeration Gases

R404a is a hydrofluorocarbon (HFC) blend refrigerant commonly used in commercial refrigeration systems.

It is known for its low-temperature applications, such as in supermarket freezers and refrigerated transport.

R404a has a high global warming potential (GWP) and is being phased out in many regions due to environmental concerns.
