Air-Cooled Magnetic Bearing Chiller

Chilled water system for commercial applications

This air-cooled magnetic bearing chiller offers exceptional efficiency and is easy to operate. It's equipped with an advanced evaporator and high-performance condenser designed and produced in-house, and runs on our low-energy, low-noise external rotor fan. For precise temperature control with an accuracy of ±0.1°C, the compressor is frequency-converted and can be controlled. The cooling capacity of the unit is 857 kW, and its chilled water outlet has a temperature range of 5-20°C. Additionally, non-standard units are available to satisfy any customized requirements. This air-cooled chiller can operate normally even in adverse environments, from -5 to 43°C, making it suitable for all kinds of small and medium-scale commercial and industrial facilities.

Request a Quote Features The cooling capacity of this chiller spans 420-7800kW, providing water at temperatures as low as 5°C. We supply standard models, but also customize non-standard products to fit customers’ individual needs. Furthermore, we manufacture chillers for seawater and other sources. Two-stage centrifugal compression sets a new bar for efficiency and stability. It utilizes a system economizer to add an extra level of compressor performance, increasing cooling output up to 10%. Further, its design provides even greater stability and safety than conventional centrifugal chillers. The DC frequency conversion motor helps optimize efficiency and reduce energy consumption. A high-efficiency, refrigerated cooled permanent magnet synchronous motor is able to run at rapid speeds. Its efficiency is impressive, reaching a maximum 97%. Equipped with a soft starter that causes only a small 2A current, this chiller doesn't put a strain on the grid. Add to that its efficient heat exchanger that provides optimal performance - this is a top-of-the-line device you can depend on. Utilizing independent research and production, H. Star can create and implement high-performance heat exchangers, in combination with the electronic expansion valve and liquid level sensor to monitor and regulate liquid levels and maintain maximum efficiency during heat exchange operations. The IPLV rating for this chiller is up to 10.7 and its partial load COP value is greater than 13. Specifications
