Gas Cooling System

  • Product Description

The gas cooling unit is equipped with ultra-low temperature self-cascading low temperature cooling technology to achieve low temperature and ultra low temperature cooling. A low temperature gas or an ultra-low temperature gas can be obtained by passing a constant temperature gas of a certain flow rate and pressure into the gas cooling device. Widely used in aerospace, automotive, defense, semiconductor and other industries, requiring lower temperature gas work requirements.

Minimum output temperature -15℃, -30℃, -60℃, -85℃, -120℃, customizable -135℃ gas cooler
The standard gas has a maximum flow rate of 25m3/h and an optional gas flow rate of 50m3/h within 10bar.
All calculations are based on 20m3/h 4bar low dew point dry compressed air (ambient temperature 25℃)








Minimum Outgassing Temperature






Refrigerating Output

AT -15℃


AT -30℃


AT -60℃

Air Requirements

Air Cleaner <5um

Air Oil Content:<0.1ppm

The dew point is allowed to be 10 degrees above the minimum outlet temperature;If the medium is air, it needs to be equipped separately to meet the dew point requirements of the air dehumidifier.

Air Treatment Capacity

Max20m3/h   pressure 1bar~5bar

System Pressure Display

The pressure of refrigeration system is realized by pointer pressure gauge (high pressure, low pressure).

The circulating system pressure is displayed on the touch screen using pressure sensor detection.
