Gasketed Plate Heat Exchangers
Tailored Solutions for Industrial and HVAC Applications

OnePHE’s gasketed plate heat exchangers (PHEs) consist of precision-stamped plates and gaskets, secured in a frame with clamping bolts for uniform pressure. Designed for volume flows of 0.5–4,500 m³/h and heat exchange surfaces of 0.04–3 m² per plate, they offer OEM-compatible reliability, easy maintenance, and the flexibility to add plates for increased capacity, ideal for diverse industrial needs.

Advantages of Gasketed Plate Heat Exchangers

High thermal efficiency with OptiFlow, Bypass Stop, and Best Wave systems for optimal heat transfer.
Compact design reduces investment costs, suitable for high-viscosity or contaminated fluids.
Maintenance-friendly with clip-on gaskets and turbulent flow for efficient self-cleaning.
Versatile applications with titanium plates for demanding environments like seawater cooling.
