Marine retrofit refrigerants are eco-friendly alternatives replacing older, ozone-depleting refrigerants in shipboard systems. These refrigerants are designed to work with existing marine refrigeration equipment, ensuring compliance with environmental regulations. Retrofitting involves modifying current systems to enhance efficiency and reduce global warming potential while maintaining performance.

Marine Retrofit Refrigerants:

- Size: Varies by application (typically 30 lb to 100 lb cylinders)

- Grade: High-purity, UL/ASHRAE certified

- Viscosity: Low (similar to traditional refrigerants like R-22 or R-134a)

- Buoyancy: Slightly higher than air (varies by refrigerant type)

- Material: Hydrofluorocarbons (HFCs), Hydrofluoroolefins (HFOs), or natural refrigerants (CO2, ammonia)

Marine Retrofit Refrigeration Systems:

- Size: Compact to large-scale (1 HP to 100+ HP capacity)

- Grade: Marine-grade, corrosion-resistant

- Viscosity: System-dependent (oil viscosity varies by compressor type)

- Buoyancy: N/A (stationary systems)

- Material: Stainless steel, copper-nickel alloys, or coated aluminum for corrosion resistance
