Engineering explained
See what is happening inside the exchanger.
Product imagery is paired with technical context so buyers and engineers can understand construction, flow path and configuration—not just the exterior.
01
Modular depth for different plate counts
Front and rear shells combine with removable center rings, allowing one insulation platform to cover a practical range of BPHE thicknesses.
02
Complete modular insulation assembly
Front and rear shells fit around the brazed plate heat exchanger, while removable center rings extend the enclosure to match the plate-pack depth.

Selection information
What our engineers need from you.
Confirm BPHE model, external width and height, plate-pack thickness, port positions, operating surface temperature and required fire classification before ordering.
Frequently asked questions
Key questions before product selection.
How does BPHE Thermal Insulation work?
Molded front and rear EPP shells enclose the heat exchanger while removable center rings increase the insulation depth to match the plate pack. Port openings retain piping access, and the shell can be removed for service.
What information is required to select the right product?
Confirm BPHE model, external width and height, plate-pack thickness, port positions, operating surface temperature and required fire classification before ordering.
Which materials and configurations are available?
Expanded polypropylene (EPP); Density 45–60 kg/m³; DIN 4102 fire-protection classification
How is the final product size confirmed?
The final size is confirmed by thermal calculation using flow rates, inlet and outlet temperatures, allowable pressure drop, design pressure and fluid properties.
