Box type temperature control system chiller unit with cooling and heating functions

SJFX series full liquid-semi-closed twin-screw water chillers are consistent with the characteristics of water flood screw units: high efficiency, energy saving, high reliability, simple and convenient control. The enhanced heat exchange tube can significantly improve the heat transfer capacity, and the combination with twin-screw compressor technology can greatly improve the system efficiency. Multi-compressor design not only has higher energy efficiency of partial load, but also can make the unit better standby; Siemens controller is equipped with touch liquid crystal operation screen, which can easily realize the operation and control of the unit. At the same time, we abandon some flashy functional design, based on the concept of simple operation and reliable performance, launched this economical and practical double screw chiller for customers.
