Marine Refrigeration Packages and Systems typically include the following key specifications and technical properties:
Size: Ranging from compact units (1-5 kW) to large industrial systems (100+ kW), depending on vessel size and cooling requirements.
Grade: Compliant with international standards such as IMO, SOLAS, and ISO 817 for refrigerant classification (e.g., R404A, R134a, R22 alternatives).
Viscosity: Refrigerant oil viscosity varies (e.g., ISO VG 32, 46, or 68) based on compressor type and operating conditions.
Buoyancy: Designed with corrosion-resistant materials to ensure stability and buoyancy in marine environments.
Material: Constructed with marine-grade stainless steel (316L), aluminum alloys, or coated carbon steel for durability against saltwater corrosion.
Cooling Capacity: Measured in kW or tons of refrigeration (TR), tailored to specific marine applications (e.g., cargo holds, fish processing).
Operating Pressure: High-pressure systems (up to 30 bar) for efficient heat exchange in varying sea conditions.
Power Supply: Typically 380-440V AC, 50/60Hz, with options for marine electrical standards (e.g., IEC 60092).
Insulation: High-density polyurethane or PIR foam to minimize heat transfer and improve energy efficiency.
Refrigerant Type: Low-GWP (Global Warming Potential) options like R513A or natural refrigerants (CO2, ammonia) for eco-friendly compliance.
