Marine container refrigeration systems are specialized units designed to maintain precise temperature control for perishable cargo during transport. These systems are built to withstand harsh marine environments while ensuring consistent cooling or freezing conditions. They typically feature robust components like compressors, condensers, and evaporators to handle varying thermal loads efficiently.

Size: Typically 20ft or 40ft standard container dimensions, with internal volume ranging from 28 to 67 cubic meters.

Grade: Designed to meet ISO 1496-2 standards for refrigerated containers.

Viscosity: Refrigerant viscosity varies by type (e.g., R134a, R404A) but typically ranges from 0.2 to 0.5 cP at operating temperatures.

Buoyancy: Not applicable as these systems are installed in fixed containers; buoyancy is not a design factor.

Material: Exterior made of corrosion-resistant steel (Corten steel); insulation often polyurethane foam; evaporator and condenser coils typically aluminum or copper.

Temperature Range: Capable of maintaining -30°C to +30°C, depending on the model and refrigerant used.

Power Supply: Typically 440V AC, 60Hz, or 380V AC, 50Hz, with options for diesel generator backup.

Refrigerant Type: Commonly uses R134a, R404A, or R410A, with newer models transitioning to low-GWP alternatives.

Cooling Capacity: Ranges from 3,000 to 15,000 BTU/hr, depending on container size and application.

Insulation Thickness: Typically 50-100mm of polyurethane foam for optimal thermal efficiency.
