Acid proof air/air heat exchanger

Gupex AS delivers 8 acid proof air to air plate heat exchangers to large surface treatment plant.

GUPEX® acid resistant air to air plate heat exchangers where selected to be fitted in both the process air and the general ventilation of a large surface treatment factory. 100000 m3⁄h (59000 cfm) of air divided into four air-air heat exchangers for the general ventilation and 100000 m3⁄h (59000 cfm) divided into another four air⁄air heat exchangers for the process air.

The process air contains several corrosive and otherwise hostile chemicals including:

  • Hydrofluoric acid, HF
  • Nitric acid, HNO3
  • Hydrocloric acid, HCl
  • Sodium hydroxide (lye), NaOH
  • Cyanides

to mention a few..

The presence of these gases in the air excluded the use of almost any other heat exchanger types. The GUPEX® air-to-air heat exchanger can handle these chemicals, year in, year out.
