90 Ton Industrial air cooled screw chiller 

According to different compressors, chillers are divided into screw chillers, scroll chillers, and piston chillers; according to different heat dissipation methods, chillers are divided into air-cooled chillers and water-cooled chillers. Air cooled screw chiller is a kind of industrial air cooled chiller which compressor is screw type. Industrial Air cooled chiller screw type compressor use High efficient semi-hermetic screw compressor, World  Famous Brand compressor Bitzer or Hanbell. 

90 Ton Industrial air cooled screw chiller can be chose single compressor or double compressors refrigeration cooling systems. This 100 HP Air cooled screw chiller is single screw compressor, Control Panel Use LCD touch screen (Siemens PLC), microcomputer control, user-friendly main interface, simple operation, automatic detection of cold water temperature, the system can effectively track the load on site by automatically adjusting the compressor energy, the display is intuitive and clear, and can be read at any time Various data in operation for reference. When a fault occurs, it can automatically alarm in time and display the cause of the fault for easy handling. The relevant feedback information can be output to other main control systems according to the needs of the scene. Screw type chiller evaporator adopt shell and tube type, External water tank, Pump is inside or outside chiller optional.

Air-Cooled Screw Chiller Products Information

Features:
1. The compressor adopts the international brand. The original imported international brand BITZER Germany (Bitzer) HANBELL China Taiwan (Hanbell), a new type of high-efficiency screw rotor compressor, the efficiency is 20%-30% higher than the general compressor.
2. High efficiency 5:6 patented asymmetric rotor tooth profile.
3. Capacity control can adopt four-stage (100%-75%-50%-25%) or three-stage (100%-66%-33%) and stepless control system.
4. The combined design of 11 bearings and a-type axial thrust balance drum greatly increases the bearing life by 2.5-3.5 times.
5. The use of high-efficiency silicon steel sheet special groove design, and equipped with internal and external omnidirectional design cooling channel, so that the compressor motor can play the highest efficiency under any load.
6. The unique built-in oil pressure system does not need an oil pump to ensure that the compressor maintains the best lubrication effect. The oil separator adopts a double-layer filter method, which has a good oil filtering effect and the heat exchanger can exert its maximum capacity.
7. High efficiency, low noise and low vibration.
8. A variety of refrigerants are available. In addition to R22 refrigerant, environmentally friendly refrigerants such as R134a and R407c can also be used.
