In a cross flow heat exchanger, the supply and exhaust airflow perpendicular to each other separated by aluminum plates which transfer the heat from one side to the other.
With Heatex plate heat exchangers, up 90% of the heat in the exhaust air is transferred to the supply air. No moving parts and strong aluminum plates in high standard alloy give the products a long lifetime and minimal need of service. The design allows for rapid and thorough cleaning and servicing. We offer a wide range of design options regarding, materials, sizes and components for all of our cross flow heat exchangers to suit various applications and performance requirements. Select a model below for detailed information, suitable options and accessories.
Every model has a clear advantage depending on the application. Model H2 is our most efficient cross flow heat exchanger to date. Model H has the widest set of options and configurations whereas Model P is our most robust aluminum heat exchanger. Model Z is designed to operate in extremely corrosive environments and heavy-duty applications. To determine which model suits your application, please use our comparison table below.
Heatex cross flow heat exchangers consist of corrugated plates, a frame of extruded aluminum corner profiles, and aluzinc steel endplates (for smaller sizes, we use aluminum). We do not use any flat plate laminar flow designs.
Standard-sized plate heat exchangers require no rib plate separators or other support for structural reinforcement.
Heatex’s corrugation pattern increases turbulence and heat transfer without creating stagnation points.
Depending on the plate spacing, our cross flow heat exchangers withstand the maximum differential pressure listed under each model without permanent deformation.
Depending on the temperature requirements, plate corners are sealed with either silicone or silicone-free material.
Adhesive in the plate folds limits leakage to 0.1% at 400 Pa (1.6″ WC) differential pressure. Leakage is defined as 0.1% of the rated airflow of the individual module.
After installation, the entire transfer surface is visible for inspection and cleaning without removing the exchanger. Wider plate spacing facilitates even more accessible and thorough inspection.
