LNEYA water cooled screw chillers Characteristics

  • Efficiency
    The efficiency of the screw chiller refrigeration determines the efficiency of the process. LG-80℃~30℃ is a water cooled chiller that can operate normally at very high ambient temperatures.
  • Quick return
    As a cost-effective screw chiller plant, LG-80℃~30℃ provides lower operating costs, and you can recover your costs in as fast as two years – guaranteed by our 15+ years of design, production, sales, and service experience.
  • Design optimization
    People often worry about whether the screw chiller is suitable for placement in their site, and LNEYA solves this problem. We achieve greater flexibility, smaller footprint, and better performance through professional design, and use customized solutions to unlock the limitations of the site.

 LG series utilizes advanced semi-hermetic screw compressors, along with components such as heat exchangers, evaporators, and horizontal shell-and-tube heat exchangers. Additionally, safety devices and an oil recovery system are designed to ensure energy efficiency, environmental friendliness, low noise, and other performance advantages, while safeguarding safety during both the production and operation processes.

Screw water chillers provide chilled water ranging from -25°C to 30°C and can serve as a process cooling source in applications like ice storage, low-temperature air supply, and other production processes.
