Modular Air Cooled Water
 

Description
The VM series modular air cooled water chiller uses the concept of modular design, which is heat pump or cooling only. It can control the capacity effectively according to the turn on/off of the compressor, and increase the reliability for a less time of turning on/off than a single compressor system. The start up current of the modular air cooled water chiller is controlled to a minimum. As the compressors energize one by one, the power supply cable will be smaller than the single compressor system. If one compressor fails, the other compressors can operate normally, and the impact to the user is small. It can reduce the cost of replacement as the compressor price is lower than a large one. The parallel scroll compressor system is 7% more efficient than the screw machine when full loading, and it is 15% to 20% when partial loading.
