O2-Free Air (Anti-Rusting Device for Cooling Water Using Deoxidization)

Removal of dissolved oxygen, the main cause of corrosion

Highly reliable method using compact gas separation membrane.

Stable anti-rusting effect in wide temperature range

Adaptable from high temperature water for engineering plastics molding to chiller water.

Environment friendly with small chemical use

Chemical free anti-rusting is available for chiller water. Contributes clean working condition.

Driven only by compressed air Low running cost

Need no power supply. Only compressed air at about 0.5 MPa drives the device.

Compact and easy maintenance

Space-saving compact design. Long life separation membrane saves maintenance labor.
