Radiant Cooling Chiller
The scroll air-cooled chiller is a commonly used device in the refrigeration and heating fields. The unit adopts scroll compressors, featuring high efficiency and low noise, and is equipped with a control system to achieve intelligent operation. The structure design is compact and the pipeline is simple, occupying a small area. Installation and maintenance can be completed only by connecting an external water pipe. It is equipped with multiple safety protection mechanisms and supports automatic adjustment of the compressor output according to the load. Suitable for different load scenarios.
The units are divided into two types: integral type and modular type. Modular units are composed of 2 to 8 modules and feature large cooling capacity, mutual backup and intermittent operation

①The unit has a compact structure, occupies a small area, and features a simple pipeline design. It only requires external water pipes and is easy to install and maintain.
② Intelligent control: The unit can automatically adjust the output of the compressor put into operation according to the load changes, ensuring that the unit maintains the best coordination with the highest efficiency at all times.
③ It adopts imported fully enclosed scroll refrigeration compressors. It features high efficiency, low noise, small vibration, reliable operation and long service life.
④ It adopts a microcomputer control system, featuring powerful safety protection, communication, fault diagnosis, automatic adaptation and other functions. It can automatically monitor various parameters and operating conditions during the operation of the unit.
⑤ The units are divided into integral type and modular type. The modular unit is assembled from 2 to 8 modules and features large cooling capacity, mutual backup, and intermittent operation.
⑥It provides multiple protection functions such as high and low pressure protection, anti-freezing protection for chilled water, power phase sequence protection, phase loss protection, insufficient water flow protection, and compressor motor overheating protection.
