64 ": nominal cooling capacity of 64kW
Main components: The assembled refrigeration unit for ships has two sets of compression condensing units. Under normal conditions, one set of compression condensing units is used for operation, and the other set is used as a backup. The compression condensing unit mainly consists of a refrigeration compressor, a marine condenser, a liquid storage tank, high and low temperature valve plates, an electrical control box, control components, etc.
Product Features:
Mainly used in various types of ships, vessels, ocean platforms and other places that require food preservation, providing a cold source for cold storage, maintaining the environmental temperature required for food storage in the cold storage, and keeping food fresh.
Product advantages:
The assembled refrigeration unit for ships integrates all functional components into one, which has the advantages of easy and simple operation, compact structure, stable performance, low energy consumption, low noise, impact and swing resistance, and convenient maintenance. The refrigeration device has a high degree of automation, large refrigeration capacity, large amount of cooled food, and fast speed; The high degree of automation in electrical control configuration is conducive to reducing the labor intensity of operators and saving operating energy consumption, thereby reducing operating costs; The heat exchanger components are made of copper material, which has high heat transfer efficiency, long service life, and improves the effective operating time ratio, ensuring the effective operating time of the equipment. The design, production, and delivery of refrigeration units are carried out in accordance with the specifications and standards of classification societies such as CCS, ABS, NK, DNV, etc., and can be customized according to the actual needs of customers.
