Profile: Gupex Ltd. specializes in manufacturing air-to-air industrial plate heat exchangers and heat recovery units made of glass fiber reinforced plastic (GRP) for moist, polluted, and corrosive air and gas. The industrial heat recovery units are installed and operated in moist, dusty, and corrosive industrial air environments, including most types of waste heat recovery. The GUPEX® gas-to-gas plate heat exchangers are designed for lower range temperature areas of flue gases from coal fired power station processes. The air⁄air (gas⁄gas) plate heat exchanger is a very good alternative to the rotating heat exchangers. With no moving parts, no cross contamination, or leakage, and with its chemical resistance the plate heat exchanger improves efficiency and pay-back time.
