Plate & Shell heat exchanger
Plate & Shell Heat Exchanger (PSHE)
The PSHE range of heat exchangers are new generation heat exchangers, combining the best properties of the Plate & Frame and Shell & Tube heat exchangers. The PSHE provides high heat transfer rates with a high pressure and temperature operating range. They have no gaskets, are compact, low fouling and can operate at close approach temperatures.
At the heart of the PSHE is a fully welded pack of circular plates without gaskets. This plate pack is housed within a tubular shell to provide a strong compact construction. The PSHE series have a very wide operating range with capacities of up to 100 MW / units, and can operate at pressures up to 100 bar and temperatures up to 400°C. They have a low maintenance design that provides flexibility to select different material and nozzle combinations.
Applications:
– Steam condensers and generators
– Condensate heaters and coolers
– Exhaust gas recovery
– LNG applications
– Crude oil heaters and coolers
– Gas heaters and coolers
– Hydrocarbon condensers and evaporators
– Product heaters and coolers
– Gas heaters and coolers
– Heat-recovery exchangers like feed/effluent exchangers
– Overhead condensers and gas liquefiers
– Thermosyphon and kettle reboilers
– Reactor temperature-control heat exchangers
– Cryogenic applications

– Droplet separators
– Evaporators/droplet separators (Combined)
– Cascades
– Desuperheaters
– Oil coolers
– Subcoolers
– Condensers
