Marine eco-friendly refrigerants are sustainable alternatives with low global warming potential (GWP) and zero ozone depletion. These refrigerants are used in marine refrigeration systems to reduce environmental impact while maintaining efficiency. Such systems comply with international regulations like MARPOL and prioritize energy-saving technologies.

Marine Eco-Friendly Refrigerants:

- Size: Varies (gas or liquid phase, typically stored in cylinders or bulk tanks)

- Grade: High-purity, low-GWP (Global Warming Potential), non-ozone-depleting

- Viscosity: Low (similar to traditional refrigerants like R-134a or R-404A)

- Buoyancy: Lighter than air (for most gases like R-744 (CO2) or R-1234yf)

- Material: Synthetic or natural compounds (e.g., hydrocarbons, CO2, HFOs)

Marine Refrigeration Systems:

- Size: Compact to large (modular designs for marine vessels)

- Grade: Marine-certified (compliance with IMO, SOLAS, and EPA regulations)

- Viscosity: Depends on lubricant (POE or PAG oils for compatibility)

- Buoyancy: System components designed for stability in marine environments

- Material: Corrosion-resistant (stainless steel, aluminum, copper-nickel alloys)
