Refrigeration and Air Conditioning (A/C) Systems

Dehydration of refrigeration systems and commercial refrigerants for automotive air conditioners, refrigerated vehicles, domestic refrigerators, freezers, residential air conditioners, heat pumps, etc. to prevent freezing and corrosion

· Dehydration treatment to prevent adverse chemical reactions of system materials

air brake

· Dehydration of compressed air in the braking systems of heavy and medium duty trucks, buses and trains

· PSA dryer is used to reduce the dew point of the air in the brake reservoir to below ambient temperature to prevent freezing and corrosion

air dryer

· Dewatering of plastic pellets before they are formed

· Dehydration of instrument gas

· Dehydration of indoor air with dehumidifying rotors filled with adsorbents

Polymer formulation

Dewatering of moisture-sensitive formulations—adds to polymeric coatings, epoxies, and urethanes to control the cure process, adds to coatings, adhesives, sealants, elastomers, metal-rich coatings, and vinyl Unnecessary water reactions can be eliminated in the foam
