• Applicable to various operation conditions: Leaving-fluid temperature directly controlled to within -25ºC.
   
• Entering-fluid temperature continuously monitored to detect flow or load changes.

 

• 208/230v, 380v,460v, 575v operational voltages available.

 

• Energy saving and high efficiency: The dedicated falling film evaporator has a higher heat transfer coefficient under the same working conditions and can increase the heat transfer coefficient of the heat exchange tube.

 

• The external high-efficiency oil separator adopts high-efficiency oil separation technology of collision and gravity sedimentation, and the oil separation effect is good.

• A new control logic centered on the calculation of opening method and integrating multiple protections.

 

1. PLC control-falling film type
2. Low voltage control circuits
3. Short cycle protection
4. 4Dual voltage sensor(high temperature and low temperature)
5. Temperature reset from return fluid
6. Chilled water flow switch
7. Electronic refrigerant gauges

• Adopts segmented control method to eliminate the problem of slow temperature response.

 

• The temperature control error is controlled to within ±0.5ºC, which can ensure the stability of the cold storage or bacterial room.

 

• Application of liquid spray cooling technology.
