Air/air heat exchanger
Gupex

GUPEX® industrial air⁄air heat exchangers made of glass fibre reinforced plastic (GRP) is a cost effective plate heat exchanger unit with ever improving payback time as energy prices increase, combined with very long economic life. Gupex AS has developed the technology of heat recovery from polluted and corrosive emission as well as heat recovery from low temperature process air and gas, an area which has been ignored up until now.

GUPEX type 3 air-air plate heat exchanger
GUPEX® type 3 air to air plate heat exchanger
The GUPEX® air–to–air 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 (polyester) composites, resistant of most acids and chemicals. The GUPEX® technology is used to recover heat and energy from air and gas i many industrial processes and environments, including:

Zinc plating (ventilation air heat recovery)
Galvanizing (ventilation air heat recovery)
Electro–plating (ventilation air heat recovery)
Metallurgical processes
Gas Scrubbing⁄Gas cleaning processes
Aluminium and magnesium foundries
Tumble drying air heat recovery
Welding workshop extraction heat recovery
Food processing
Woodworking processes
Paper Factory ventilation and air extraction
Machine hall ventilation and heat recovery
Cooling and reheating of air in de–humidification processes
Gas and air purification processes
