Refrigerant R404A is a high-performance, non-ozone-depleting refrigerant blend commonly used in marine refrigeration systems, particularly in low- and medium-temperature applications such as cold storage rooms, refrigerated containers, ice makers, and marine HVAC systems. As a hydrofluorocarbon (HFC) blend of R125, R134a, and R143a, R404A delivers excellent cooling capacity and thermal stability, making it a reliable choice for demanding maritime environments.

This refrigerant is known for its consistent performance, even under varying loads and harsh sea conditions, ensuring optimal efficiency for marine food preservation and temperature-sensitive cargo. It is a direct replacement for older CFC and HCFC refrigerants like R502 and R22, offering improved environmental safety with zero ozone depletion potential (ODP).

Packaged in secure, corrosion-resistant cylinders, R404A is widely used in commercial vessels, fishing boats, and offshore facilities that require robust and dependable refrigeration performance. Regular maintenance and proper handling are essential to ensure the longevity and efficiency of systems using R404A onboard.
