CLN marine water-cooled condensing unit

Marine water cooled compress-condensing unit is a supplement to marine AC unit, it splits the original marine AC unit into marine water cooled compress-condensing unit and marine AHU according to installation site requirements. It has the features of convenient operation, stable running, safety and reliability, flexible arrangement, convenient maintenance. The main function is providing suitable cooling medium for direct evaporation type terminal of marine AC system.

Product functions

The main function of marine compress-condensing unit is to provide suitable refrigerant for direct evaporation type terminal of marine AC system.

Product advantages

Marine compress-condensing unit splits marine packaged type AC unit into two. The small volume has the advantage of flexible arrangement in narrow and small space. The design, manufacture, delivery of AC unit 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.Basic parameters:

● cooling capacity:23kW~302kW

● Refrigerant: standard equip R404A, R134a、R407C can be selected

● Power supply: standard equip AC 3PH 380V/50Hz, AC 3PH 440V/60Hz, other power source can be selected if it is needed: AC 3PH 415V/50Hz, AC 3PH 460V/60Hz, AC 3PH 480V/60Hz, AC 3PH 690V/60Hz.

● Compressor: piston type or screw type (open or semi-hermetic type), standard equip Bitzer compressor, BOCK, Carrier and other brands can be selected.

● The number of compressor: single or multiple

● Single refrigerating circuit can be adopted, double refrigerating circuit also can be selected, the unit equips two independent refrigerating circuits, and each system equips one compressor. When one of the refrigerating circuits is running, the other one can be used as standby.

● Capacity regulation: multistage

● Cooling method: water cooled (fresh water/ sea water)

● Marine shell and tube type condenser: efficient anti-corrosion radiating tube, material can use HAL77-2、B10、B30; clad tube sheet; copper end cover or iron end cover.

● Replaceable dry filter

● Protection function: high pressure, low pressure, oil pressure (oil level), low water pressure (water volume), lack phase, overheat, overload

● Control elements: adopt the control valves and pressure switches of domestic and overseas famous brands

● Control method: manual control or automatic control


It is widely used in all kinds of passenger ships, cargo ships, warships and offshore oil platforms.
