Main features of H.Stars air cooled scroll compressor chiller unit:

1. Main part of Fin Type Heat Exchanger 
It adopts the hydrophilic aluminum foil to reduce the adhesion of water on the aluminum foil and greatly improve the heat exchange efficiency. The aluminum fins are packed in the copper and features uniform wind speed. With reasonable array copper pipes, it is installed in "V"-shape to improve heat exchange efficiency and reduce fan noise. The copper tube and aluminum fin are mechanically connected through expansion with high performance and stable heat exchange. 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. 

2. Main part of Compressor 
The unit 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. 

3. Main part of 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. 

4. Main part of Fan 
It adopts special low energy consumption motor patented fan nozzle to improve the air mobility and reduce the noise. Motor waterproof and dustproof grade: IP54, insulation grade: F. 

5. Main part of Controller 
The controller 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 Mod Bus RTU, TCP or S7 communication.

Advantages:
