Paper industry

The GUPEX® air to air (gas to gas) plastic plate heat exchangers operate in dusty environments without the need for air filters to protect it from clogging up the plates. The construction is made of plastic composites (polyester, GPR), resistant to most acids and chemicals.

The purpose is to extract moist and corrosive air through the air capture hoods positioned above the paper machine and supplying fresh air pre–heated through the plate heat exchanger back to the paper machine and to the machine hall.
