Overview


Fully welded plate heat exchangers (shell-and-plate heat exchangers) combine the features of conventional plate heat exchangers within a fully welded shell, yet require only a fraction of the space of an equivalent shell-and-tube heat exchanger. These exchangers are very compact, space-saving units, with a high transfer coefficient for greater efficiency. The plates also produce a high performance due to the turbulent flow created by the plate patterns.

Design benefits
• High design pressures, typically up to 60 bar, however can be designed up to 100 bar
• High design temperatures (-60°C to +450°C)
• Manufactured to all design codes including ASME VIII, PD5500
• Fully compliant with PED 97/23/EC and CE Marked
• Removable cover option available if required, allowing removal of plate pack
• Circular plate packs from 180 to 1000mm diameter
• Wide range of metallurgies including stainless steel, duplex, 254SMO and titanium

Operational benefits
• Reliable, maintenance free without gaskets
• High working temperatures and pressures; operational flexibility
• High safety (plate-pack inserted into pressure vessel; no fluid mixing)
• Can handle thermal shocks
• No leakages; environmental protection

Example fluid combinations include: water/sea-water/steam; amine/glycols; hydrocarbons; condensate; petrochemical fluids.

The exchangers have a multitude of applications within the following sectors:
• Oil and gas production and refining
• Chemical processing
• Pharmaceuticals and speciality chemicals
• HVAC, district heating, energy and utilities
• Power generation
