Air to Air Cross Flow Plate Heat Exchanger

Cross-flow heat exchanger The cross-flow heat exchanger is built from aluminum plates. Plates in special version are additionally covered with a layer of epoxy resin, between which supplying and returning air flows (streams are either cross-flow or separated from each other). Discharged air flows through some of ducts between the plates heating them,  while the fresh air flows through remaining ducts, drawing heat from heated plates. Advantages of cross-flow heat exchanger are its simple design, no moving parts and system tightness. Heat exchangers reaches efficiency of 55 to 70%. Additionally, the exchanger can be equipped with a by-pass damper, which allows air to be redirected outside the operational part of the exchanger if there is no need for heat recovery. It also serves as freezing protection for exchangers. The droplet separator is installed on the discharge side of the exchanger, which removes condensation of the airstream.
