What is involved in Relining Cooling Towers and Air Handling Units?

Posted on May 21, 2012

There will undoubtedly come a time when your Cooling Tower or Air Handling Unit’s (AHU’s) internal surfaces have become corroded or the initial coating has started to break down due to everyday use and possibly, chemical attack. While the first thought may be to replace the unit, a more cost effective and long term maybe the thorough AHU or cooling tower repair and relining we provide at COVAC.

The complete relining of the internal surfaces of your Air Handling Unit or Cooling Tower using COVAC’s Solvent Free Polyurethane System offers the ultimate corrosion resistant solution and has both chemical resistance and elongation properties accommodating the movement associated with these type of structures.
