 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.

LG series outdoor chillers Descriptions


Due to different working scenarios and uses, the requirements for screw refrigeration units are also inconsistent.
We have designed its chilled water with an outlet temperature of 7°C and a return temperature of 12°C, with a condensation temperature of 30°C. The default refrigerant is R22; if R404a, R134a, R407c, or other types are required, please specify.
If the model we show (as shown below) does not meet your requirements, please ignore it and contact us. We will tailor it for you according to your needs

Compared with the similar chillers, the screw type water-cooled chiller has many advantages：
The temperature of the heat conducting liquid can be adjusted to any temperature you want, and it runs smoothly….

The commonly used compressors at LNEYA are screw-type and scroll-type.
Screw-type chillers are primarily used in central air conditioning systems or large-scale industrial refrigeration. Scroll-type chillers, on the other hand, have smaller power compared to screw-type chillers and may not be suitable for heavy-duty applications.

In summary, air-cooled screw chiller advantages include lower maintenance costs, a prepackaged system for easier design and installation, and better performance in freezing temperature. Water-cooled screw chiller advantages include greater energy efficiency, larger capacities, and longer equipment life.
