Modular Air-cooled Screw Chiller

Description
This modular air-cooled screw chiller is a High-efficiency screw chiller that can be connected to all sorts of fan coil units to realize cooling/heating effects for civil or industrial buildings.

Features:
●V type fin structure brings this unit small refrigerant pressure loss and high efficiency. 
● With a flooded-type shell-and-tube design, the evaporating temperature is increased, and the heat exchanging efficiency improves. 
● Less noise fan blades and the special compressor noise reduction device make noise below 5dB(A). 
● Totally-enclosed design, good-looking body. 

● Special flooded screw compressor. 
A. Special motor with Grade F and thermos ability of 155°C. 
B. No speed-up gear mechanism design: twin screw compressor adopts direct-connected driving motor for reducing driving efficiency loss and for a more compact structure; 
C. Motor of the compressor is cooled down through diluent cooling of gas-absorbing cavity to lower the temperature of motor, and ensure diluent cooling of refrigeration oil. Through which can prevent decrease of insulativity due to high temperature of motor, otherwise the motor will be burnt. 
D. Built-in air exhaust check valve: it can prevent back flow of refrigerant when the unit closes down; built-in oil separator and oil heater for ensuring oil return. 
E.    Slide valve stepless adjustment for exact match of cooling output and load of compressor. 
F. High accuracy SKF shaft bearing: This twin screw compressor adopts high accuracy SKF shaft bearing so that the clearance of compressor can be smaller, transmission efficiency will be higher, energy efficiency ratio of compressor will be higher, and service life of compressor will be longer.
