HVAC Manufacturers Modular System Scroll Compressor Water Cooled Chiller


Compressor

The scroll compressor chiller adopts famous brand compressor with middle bearing cap to achieve high energy efficiency and low sound level. The unit runs quieter and more efficient, with the scroll design of "contact-free and wear-free", it can reduce friction.


Shell and Tube Heat Exchanger

The copper tube of the evaporator adopts 1.1mm thick copper heat exchange tube, which ensures that all products meet the high requirements of high efficiency, energy saving, safety, strong antifouling ability and durability.

According to the customer's use conditions and water quality factors, different materials of heat exchange tubes can be selected, ensuring the high efficiency and energy saving and service life of the unit.

It is independently designed and manufactured with strict quality control. Configuring according to the place of use and process, it ensures that the heat transfer coefficient meets the design requirements.


Controller

The modular chiller system adopts the highly integrated button-type human-machine interface control center, which greatly improves the anti-interference ability of the system.

The product adopts plastic shell, which is easy to install.

The front and rear panels exchange data through 485 communication, and the entire system can be integrated or separated. Siemens PLC controller can also be selected to realize ModBus RTU, TCP or S7 communication.
