Overview

AIST CO2 Module Unit

The AIST series carbon dioxide module unit is a new type of high-efficiency refrigeration equipment built on MOON-TECH’s promotion and application experience of CO2 refrigeration technology and related refrigeration systems. The unit uses a number of innovative technologies, such as the CO2 screw compressor, no-liquid-storage micro-pressure-drop small-charge condenser, combined rotary gas-liquid separation and micro-gravity liquid level control technology, and automatic intelligent control technology. The whole machine is skid-mounted, without a refrigeration control room — safe, energy-saving and environmentally protected. At present, the unit has been widely used at home and abroad.
