Marine Freezer Units and Refrigeration Systems typically feature the following specifications:
Size: Ranging from compact (1-5 HP) to large industrial systems (50+ HP), with dimensions varying based on capacity.
Grade: Designed to meet marine-grade standards (e.g., ABS, DNV, or Lloyd's Register certification).
Viscosity: Refrigerant viscosity depends on type (e.g., R404A, R134a, or ammonia) and operating temperature (-40°C to +10°C).
Buoyancy: Systems are engineered for stability, with components secured to withstand vessel motion and prevent buoyancy-related issues.
Material: Corrosion-resistant materials like stainless steel (AISI 316), aluminum, or marine-grade coatings for durability in saltwater environments.
Cooling Capacity: Typically measured in kW or BTU/h, varying from 3 kW (small units) to 100+ kW (industrial systems).
Insulation: High-density polyurethane or PIR foam to minimize heat transfer and improve efficiency.
Power Supply: 220V/380V AC, 50/60Hz, or customized for marine electrical systems.
Refrigerant Type: Low-GWP options (e.g., R513A, R744) or traditional (R22 alternatives).
Compressor Type: Hermetic, semi-hermetic, or screw compressors for varying load demands.
Defrosting: Electric, hot gas, or water defrost systems for ice prevention.
Weight: Varies by size (50 kg for small units to 1000+ kg for large systems).
Pressure Rating: Designed for high-pressure operation (up to 30 bar for some refrigerants).
