Detailed

Water-Cool Industrial Chiller Room Temperature Double-Unit 2

 

1.Features Of Unit

(1)The machine is adopted with international advanced semi-enclosed 5:6 asymmetrical twin-screw  compressor. Motor, compression chamber integration, no shaft leakage.
(2)The compressor is adopted with Y-△ reduced-voltage start to avoid the impact on the grid.
(3)The machine has realized multi stage automatic control of refrigerating capacity adjustment.
(4)Exchanger is adopted with imported high efficiency heat exchange chopper tube, so the heat exchange efficiency is high.
(5)The machine is adopted with liquid spray system, so it can effectively reduce the oil temperature of the compressor and greatly improve efficiency of unit under low temperature condition.
(6)The imported PLC man-machine interface is a LCD touch screen, which is graphical display, easy to operate, optional in English and Chinese. The machine is equipped with RS485 National standard communication, can be connected with DCS system and access to the entire factory automation network, easy to remote control and monitor.
(7)The machine can automatically detect outlet water temperature or return water temperature, adjust the slide valve by controlling the compressor capacity and the refrigerating capacity of the unit automatically and let the operation more energy efficient.
(8)The machine can automatically record the first 20 warning points, so it is convenient for the maintenance personnel to judge and maintain the unit in time.
(9)Low noise and low vibration, designed according to industrial standard,suitable for 24 hours running all year round.
(10)The running parts of the machine are only screw bearing, which has low maintenance cost and long service life.
