Working principle

How the technology transfers heat.

Corrugated plates are welded into a sealed heat-transfer block and secured inside an external pressure frame. The two media pass through alternating channels, while X low-theta and D high-theta plate patterns allow thermal performance and pressure drop to be matched to the duty.

Construction
Fully welded plate block within a pressure-retaining frame
Maximum design pressure
Up to 40 bar
Maximum design temperature
Up to 400°C
Published plate area
0.08 to 1.85 m² per plate
