Semi-Welded Plate Heat Exchanger – ParaWeld
Welded plate pairs design
Field of application : Widely used for single and two-phase heat transfer in refrigeration, chemical, industrial and petrochemical markets. Designed with welded channels allowing handling of aggressive fluids
Descriptions : Corrugated plates welded in pairs. Pairs are separated by gaskets (welded pairs on process side, normal gasket technology on the secondary side)
Materials : AISI 316, AISI 304, Titanium, C2000, and most alloys. Gaskets : NBR, EPDM, FKM, and other types
Temperature : -45 – 250°C (-49 – 482°F)
Pressure : 0 – 35 bar gauge (0 – 507 Psi)
Transmission area/duty : Up to 2,000 m2 (21,528 ft2)
Maintenance access : Welded side : Cleaning by circulation of cleaning fluids (CIP) Gasketed side : Full access for cleaning and inspection
Advantages
– High efficiency due to full countercurrent flow
– Reduced risk of leakage
– Resistant to thermal stress
– Compact and space-saving design
– Possibility to combine different gasket materials for cost-effective solution
