Marine refrigeration evaporators are essential components in ship cooling systems, designed to absorb heat from refrigerated spaces. They operate by circulating refrigerant that evaporates, extracting heat and maintaining low temperatures. These evaporators are built to withstand harsh marine environments, ensuring reliable performance for cargo and provision cooling.

Marine Refrigeration Evaporators:

- Size: Typically 1.5 to 12 meters in length, depending on vessel requirements.

- Grade: Marine-grade stainless steel (316L) or aluminum alloys for corrosion resistance.

- Viscosity: Designed for low-viscosity refrigerants (e.g., R404A, R134a).

- Buoyancy: Neutral buoyancy in seawater, with reinforced mounting for stability.

- Material: 316L stainless steel, copper-nickel alloys, or aluminum.

- Operating Pressure: 10 to 30 bar, depending on refrigerant type.

- Temperature Range: -40°C to +10°C for standard applications.

Marine Refrigeration Systems:

- Size: Compact modular designs, 2 to 20 kW cooling capacity.

- Grade: Marine-certified (DNV, ABS, or LR standards).

- Viscosity: Compatible with low-viscosity refrigerants and marine oils.

- Buoyancy: N/A (fixed installation).

- Material: Stainless steel, copper, and marine-grade polymers.

- Operating Pressure: 15 to 45 bar, depending on system type.

- Temperature Range: -50°C to +50°C for extreme conditions.

Marine Refrigeration Evaporators and Marine Refrigeration systems typically comply with maritime standards such as those set by the International Maritime Organization (IMO), including SOLAS (Safety of Life at Sea), and may also meet classification society requirements like those from ABS, DNV, or Lloyd's Register.
