Marine Refrigeration Oils Supplier - Refrigeration Systems

Marine refrigeration oils are specialized lubricants designed for use in shipboard refrigeration systems, ensuring efficient compressor operation and thermal stability. These oils must withstand harsh marine environments, including high humidity, salinity, and temperature fluctuations. Refrigeration systems in marine applications rely on these oils to maintain cooling performance while preventing corrosion and component wear.

Marine Refrigeration Oils:

- Viscosity: ISO 32 to ISO 220 (common grades: ISO 68, ISO 100)

- Grade: Mineral, synthetic (POE, PAG, AB), or semi-synthetic

- Material: Alkylbenzene (AB), Polyolester (POE), Polyalkylene Glycol (PAG)

- Buoyancy: Typically denser than water (non-buoyant)

- Compatibility: Must match refrigerant type (R22, R134a, R404A, etc.)

- Flash Point: >150°C (varies by type)

- Pour Point: Below -30°C for low-temperature applications

Marine Refrigeration Systems:

- Size: Ranges from small (1-5 HP) to large (50+ HP) compressors

- Refrigerant Types: Ammonia (R717), CO2 (R744), HFCs (R134a, R404A)

- Operating Pressure: Low (R134a) to high (CO2, Ammonia)

- Material: Copper, stainless steel, or aluminum for corrosion resistance

- Cooling Capacity: 1 kW to 500+ kW (varies by system size)

- Viscosity Requirements: Matched to compressor type (reciprocating, screw, centrifugal)

- Buoyancy: System components designed for marine stability
