The crossflow plate heat exchanger with flange frame is intended for systems in which the plate pack does not sit inside a unit but directly between the ducts.
Design
The plate pack is enclosed in a surrounding frame. Each of the four connection sides has a flange face for the duct, so the frame separates the two air paths without an additional casing.
Applications
Typical uses are heat recovery in ventilation systems and process exhaust air, when the heat exchanger is fitted into existing ducts. Material and plate spacing are sized to your operating data.

Strengths
- Direct duct connection without a separate unit casing
- Plate material selectable to suit the medium
Limits
- Frame and flanges need space in the duct network
- Without dampers there is no bypass for frost protection or free cooling
