Refrigerants: The Differences Between R134a, R404A and R290

The refrigerant is the substance that carries heat around the refrigeration cycle. Choosing the right one directly affects both the efficiency of the system and how long it runs well. Here are the three you will meet most often.

R134a

A stable, dependable refrigerant widely used in medium temperature applications. It is a common choice in domestic refrigerators and commercial coolers.

R404A

Developed for low and medium temperature commercial refrigeration. It delivers strong performance in cold rooms and industrial refrigeration systems.

R290 (propane)

A natural refrigerant, R290 stands out for its low environmental impact and high energy efficiency. It is increasingly the preferred option in systems designed around it.
