Covai Air Products | CorporateAnnealing For Metals Materials Processing
For Metals and Materials Processing


For virtually any annealing operation, Covai Air Products has an atmosphere that’s ready to perform. Whether you are annealing ferrous or nonferrous metals, our wide range of atmosphere solutions can ensure that your special atmosphere requirements can be fully satisfied.

Since many of our atmospheres contain none of the unreacted hydrocarbons that are typically found with traditional exothermically-generated atmospheres, the improvement in surface quality often allows for a significant reduction in post-heat treatment cleaning or pickling costs, sometimes by as much as 80%. We also have a cooling application for temper rolling.

Heating Treating Solutions

Covai Air Products offers a wide range of technologies, gases, equipment, and cutting-edge solutions for the heat treating industry.
