Adopts flooded evaporator design and high-efficiency heat exchange copper tubes. The evaporator tubes are fully immersed in boiling liquid refrigerant to enhance heat exchange on both water and refrigerant sides, effectively improving the cooling capacity and COP of the unit. The compressor uses a slide valve for stepless capacity regulation, which stably adapts to changes in air conditioning load and boosts energy efficiency under partial load operation.

Equipped with brand compressors. Each pressure vessel is provided with the Special Equipment Design License and Special Equipment Manufacturing License of the People's Republic of China. Units with dual or more systems adopt multiple refrigeration circuits. When one circuit is under maintenance, the rest can still operate normally with backup function.

It features a specially designed oil return system with an external high-efficiency oil separator and dedicated oil return device to ensure complete oil return. The uniquely designed throttling device can automatically adjust flow rate according to load changes and maintain stable system pressure difference.

The compressor achieves a trouble-free running time of over 40,000 hours for safer use. All units undergo 100% strict inspection at professionally certified test stations before delivery to guarantee reliable performance. The product features simple installation, convenient maintenance and easy upkeep.
