A marine refrigeration system is a key element onboard any vessel. Food and drinks, cargo and garbage as well always need to be kept in optimal conditions. Well-maintained food and

drinks are essential for passengers’ and crew’s health. And obviously, cargo ships need to be equipped with high quality marine refrigeration and air conditioning, as their core business is to assure the quality of the cargo during transport.

Marine refrigeration for any vessel

SAIGON - CUULONG MARINE SERVICES CO.,LTD has an enormous expertise in the engineering of marine refrigeration systems onboard any vessel; from yacht refrigeration to refrigeration systems onboard merchant ships, naval ships and offshore accommodation vessels. A few examples of our commonly supplied refrigeration systems are:

1. Garbage cooling                         

2. Provision cooling

3. Custom-built refrigerating rooms and cabinets

4. Morgue cooling

5. Seawater or freshwater cooled condensing units

6. Air-cooled condensing units

7. Fan coils in the cold rooms

8. Evaporators

Custom-built marine refrigeration 

No vessel is the same and therefore Saigon Cuulong will always provide you with a custom-built solution to your specific needs. We work together with our clients in order to make the most suitable systems for the vessel. We can design refrigeration systems that are explosion proof and suitable for zone 1 & zone 2 as well.

How a refrigeration system works

- The refrigeration cycle consists of five components:

- The refrigerant: R22, R44 is an often used refrigerant

- The compressor: We use Turbocor compressors in our systems as these are exceptionally sustainable, totally oil-free and take up half the space of conventional compressors.

- The condenser: Our condensing units are either sea-water cooled, fresh-water cooled or air-cooled.

- The evaporator

- The expansion device

The refrigerant starts as a gas and is compressed in the compressor, which increases its temperature dramatically. Thereafter, the condenser cools the hot high pressure refrigerant and this way the refrigerant turns into a liquid. Next, the evaporator boils the refrigerant back to a gas, at a very low temperature. The change from liquid to gas absorbs the heat from the evaporator, which in turn removes the heat form the insulated refrigeration box, thereby lowering its temperature. Hereafter, the refrigerant is returned back to the compressor  and the refrigeration cycle starts again.
