GEAShell

Extremely reliable GEAShell is a fully welded plate heat exchanger which satisfies very exacting requirements in relation to process reliability. The heat exchanger plates designed for individual solutions are welded into a pack and mounted in the fully welded pressure vessel. This design principle ensures that the exchanger is both highly resistant to pressure and temperature and also leak-tight. Media are fed in through ports on the pressure vessel, the ports’ position being determined by customer requirements.

GEAShell is rated for extreme temperatures of –200°C to +950°C and operating pressures of up to 100 bar.

For use in the process industry, refrigeration and power generation, the chemical industry and in marine applications GEAShell is configured so as to accord with technical requirements and at the same time minimise capital outlay and running costs.
