Product Description

Description

   The series water chiller used the efficient screw compressor from European, with its own superiority: high energy efficiency, low noise, high reliability, small footprint, easy installation, simple operation and high flexibility. It is widely used in surface engineering, medicine, chemical industry, metallurgy, leather, laser, electronics, plastic injection molding, printing and other industries. The series water chillers have too many models. It can achieve a perfect match for industrial applications.


Safety system:

   1  Compressor reverse protective 

   2  Freeze protector protective 

   3  Refrigerant safety valve 

   4  Buzzer

   5  High-pressure gauge and Low-pressure gauge 

   6  Power phase failure protector 

   7  Coil over-heat protector 

   8  Temperature auto-switch 

   9  Refrigerant shortage protective
