Marine Eco Friendly Refrigerant Gases Supplier - Gas Systems

Marine eco-friendly refrigerant gases are sustainable alternatives designed to reduce environmental impact in marine cooling systems. These gases, such as R-744 (CO2) and R-1234yf, have low global warming potential (GWP) and zero ozone depletion potential (ODP). Gas systems utilizing these refrigerants ensure compliance with international environmental regulations while maintaining efficient performance.

Marine Eco-Friendly Refrigerant Gases:

- Common Types: R-744 (CO2), R-717 (Ammonia), R-290 (Propane), R-600a (Isobutane)

- Size: Typically stored in cylinders (10kg to 50kg) or bulk tanks (100kg+)

- Grade: High purity (99.5%+), ASHRAE/AHRI standards compliant

- Viscosity: Low (varies by gas, e.g., CO2 ~0.015 cP at 25°C)

- Buoyancy: Lighter than air (R-290, R-600a) or heavier (R-744, R-717)

- Material Compatibility: Stainless steel, copper, aluminum (avoid brass with ammonia)

- Pressure Range: Low (R-290, R-600a) to high (R-744, up to 100+ bar)

- ODP (Ozone Depletion Potential): 0

- GWP (Global Warming Potential): Low (e.g., R-744 = 1, R-290 = 3)

- Flammability: A3 (highly flammable) for hydrocarbons, B2L (toxic) for ammonia

- System Type: Direct expansion, cascade, or secondary loop configurations

- Operating Temp Range: -40°C to +80°C (varies by refrigerant)

- Leak Detection: Required for flammable/toxic refrigerants (sensors/alarms)

- Certification: IMO, ISO 817, EN 378, IEC 60335-2-40 compliant
