LinkedIn

Model: LG16M12M—LG40M32M Series

Refrigerants: R717 (Ammonia), R507, etc.

Design Conditions: +40°C condensing / -40°C evaporating temperature

Nominal Cooling Capacity:

117 kW – 1450 kW (R717)

157 kW – 2142 kW (R507)

Product Features

Designed for low-temperature applications with evaporating temperatures below -25°C; significantly more efficient than single-stage compressor units with economizers

Various configuration options available based on refrigerant and operating conditions:

For R717, the pressure ratio between high and low stage ranges from 3 to 4

For R507A, the pressure ratio ranges from 2 to 3

Both high-stage and low-stage compressors are equipped with capacity regulation systems, ensuring high efficiency and economical operation under all low-temperature conditions

Staged startup for high- and low-stage compressors to minimize inrush current; low-stage compressor utilizes differential pressure oil supply

High-stage compressor can operate independently for rapid cooling with high efficiency

Compatible with multiple refrigerants, including R717, R507A, and R404A

Various configurations available to meet customized requirements

Standard control mode: automatic
