Semi Welded Plates- Para Welded


Field of applicationL: 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

Description:Corrugated plates welded in pairs. Pairs are separated by gaskets (welded pairs on process side, normal gasket technology on the secondary side)

Material Plates: AISI 316, AISI 304, Titanium, C2000, and
most alloys
Gaskets: NBR, EPDM, FKM, and other types

Temperature Rubber gaskets: -45 – 250°C (-49 – 482°F)

Pressure 0 – 35 bar gauge (0 – 507 Psi)

Transmission area/dutyUp 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




  • 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
