Model: LG1612MM—LG3225LS Series

Refrigerants: R717 (Ammonia), R507, R404, etc.

Design Conditions: +40°C condensing / -35°C evaporating temperature

Nominal Cooling Capacity: 139 kW to 1262 kW

Application Range: Designed for low-temperature refrigeration applications with evaporating temperatures below -25°C.

Product Features

Specifically designed for low-temperature applications below -25°C, offering significantly higher efficiency compared to single-stage compressor units with economizers

Four models available, including both single-stage and two-stage screw compressor units; for models LG2016MS, LG2520MS, and LG3225LS, both the high- and low-stage compressors are equipped with capacity control devices to ensure optimal efficiency and cost-effectiveness under various low-temperature operating conditions

Customizable configurations available to meet specific user requirements

Standard control system provided in automatic mode
