Marine quick-freezing refrigeration plant is a refrigeration unit after several years of continuous technical improvement, carrying the technology security and innovation; it is direct refrigeration unit takes refrigerant as cooling medium. Marine quick-freezing refrigeration plant is important equipment of ships, oil platforms food cold room refrigeration system, the temperature can be adjusted according to the requirements of food preservation, to satisfy the food fresh keeping requirements. Especially the explosion-proof design and treatment will broaden the application range, it can be used in the environment with flammable and combustible gas, this refrigeration plant has features of new design, smart control, convenient operation, energy saving, reliable running, reasonable safety precautions and so on. It can be widely used in various passenger ship, cargo ships, naval vessels and oil platforms.

Marine quick-freezing refrigeration plant is composed of compress-condensing unit, control valves, terminal quick-freezing unit. Compress-condensing unit is mainly composed of refrigeration compressor, marine condenser, liquid receiver, high and low temperature valve plate, electric control box, control elements.
It is mainly used in all kinds of naval vessels, ships, marine platforms where food preservation is needed, it provides cold source for cold rooms, mainly used to maintain the temperature required by food preservation, keep food fresh.
Marine quick-freezing refrigeration plant sets all functional components in one; it has the advantages of convenient and simple operation, compact structure, low energy consumption, low noise, shock and swing resistance, convenient maintenance etc. The refrigeration plant automation degree is high, speed is fast; all heat exchange components adopt copper material, the corrosion resistance is strong, ensure the equipment effective operation time. The design, manufacture, delivery of refrigeration plant is conducted according to the standard of classification societies (such as “CCS”, “ABS”, “NK”, “DNV”) and “navy”, and it can be manufactured according to customer’s actual demands.
