Product Features:
Modular design:
Each microcomputer controller of the unit reserves the interface for connecting the combined control module.
Networking control between units can be implemented by cable connection and simple master-slave settings.
Maximum 8 chillers can be controlled in a combined system, which means that the capacity can be easily expanded to meet various air-conditioning requirements. In a combination system, if one module failed, other modules can be back-up for continuing operation.
Reliable operation:
All parts and control components of the central cooling chiller are provided by world-famous reliable suppliers to make the unit highly efficient, energy saving, and reliable, such as Bitzer Comp. & Danfoss EXV, Schneider electric etc.
Central cooling chiller uses the advanced electronic expansion valve, which ensures excellent performance both under full load or partial load and higher control accuracy.
Each central cooling chiller was extensively tested before delivery to verify its operational reliability and to ensure a smooth startup.
The performance, reliability and structure of the unit are verified and optimized by the long-term simulation tests under various changing conditions and extreme conditions.
Easy and fast installation:
The water pipe of the water-side heat exchanger has been equipped with the water flow switch and is ready to use, which saves the on-site installation time.
Inlet and outlet pipes are equipped with flange connection, which makes the on-site installation easier.
The central cooling chiller comes with the startup cabinet and control cabinet and has been filled with refrigerant and refrigeration oil before delivery. The unit can be placed in service after being connected with power supply and water supply during field installation.
The built-in hydraulic module is optional. This module integrates all necessary hydraulic components such as the water pump, filter, expansion tank, flow switch, safety valve, pressure gauge, and drainage valve.
Option:
Low ambient temperature COOLING.
Process cooling unit. Provide customized inlet/outlet water temperature condition.
Refrigerant is optional, capacity can be ordered based on projects requirement.
Cooling only or Cooling and Heating. Heat recovery.
Build-in hydraulic module.
