Marine R134a Refrigerant is a non-toxic, non-flammable hydrofluorocarbon (HFC) used in marine refrigeration systems. It is designed for efficient cooling in boat and ship applications, offering reliable performance in harsh marine environments. R134a systems are commonly used for air conditioning and refrigeration due to their environmental safety and compliance with regulations.
