Air Handlers Air Cooled Screw Chiller Water Cooled Water Chiller
1. Eurostars water cooled commercial screw chiller main components
(1)Compressor
*Adopt world famous screw type compressor, proven quality.
*Most advanced high efficiency 5:6 asymmetric tooth type screw
*Semi-hermetic design, with less components, lower fault performance.
(2)Condenser
*Cleanable water cooled condenser is made of thread copper tubes, with the advantage of high efficiency, can be designed to be corrosion resistant and stable heat transfer.
(3)Evaporator
*Adopt dry type (DX) shell and tube evaporator, outer rolled material of the evaporator is soft thermal insulation, efficiently avoid heat transferring between evaporator and outdoor air, reduce energy consumption.
(4)Dry filter
*Dryer filter can filtrate water, acid and easy to replace.
(5)Expansion valve
*Adopt imported expansion valve, aim to adjust refrigeration flow into evaporator according to evaporating temperature, and maintain a certain pressure so as to ensure the evaporating efficiency.
(6)Controller
*Advanced microcomputer intelligent control HMI system, inbuilt Eurostars control algorithm with special design, energy efficiency and reliability is much more outstanding.
*Touch screen display design, PLC controller is optional.
