Marine Chilled Water Unit
Ship cooling water chillers can provide chilled water for ship air conditioning systems, low-sulfur oil cooling systems and other special applications. The device is composed of a semi-hermetic piston compressor or a twin-screw semi-hermetic compressor, a water-cooled shell and tube heat exchanger, a dry expansion evaporator, an expansion valve, a filter, a sight glass, a shut-off valve, a control box, etc. After connecting the power supply, cooling water system and chilled water system, the user can conveniently operate the unit.
l The available compressor types include open type, semi-closed type, and fully closed type.
l Feature: reliable run, anti corrosive and complete protections
l Cooling capacity: 50kW ~ 2000kW
l Refrigerant: R407C、R134a、R404A、R22、R410A、R407F、R407H、R448A、R449A，R513A、R32、R454C
l Compressor: piston or screw type/open or semi-hermetic
l No of compressor : single or multi
l Capacity control: multistage selectable
l Cooling method: water cooled or air cooled
l Water cooled condenser; high efficient anti corrosive
Condensing tube: Cu、B10、B30
l Air cooled condenser : copper tube copper fin, inner high efficient tube
l Protection : high pressure, low pressure, oil pressure(oil level),
low water pressure(water flow), anti freeze, lack phase, over voltage, under voltage, overheat and overload
l Control: button control or PLC control
l Power supply: 3-380V/50Hz , 3-44OV/6OHz
l Washable shell and tube shell and tube heat exchanger, fresh water cooling type uses brass heat exchange tubes; sea water cooling type uses copper-nickel heat exchange tubes.
l The chilled water temperature can be set through the panel, and the temperature is automatically controlled.
l The pressure test, vacuum test, and aging test have been completed before leaving the factory.
l Suitable for long-term operation in marine environment.
