The APV ParaWeld is a range of laser-welded plate pairs for refrigerant and chemical processing and a logical alternative to shell and tube and all welded pates. The pairs are particularly suitable for evaporation and condensing of refrigerants such as ammonia and Freon, as well as chemical and general process duties involving aggressive liquids that would attack conventional gaskets.
The APV ParaWeld consists of plates welded in pairs using a patented laser-welding process. Each second channel is secured by a welding, and the other channels by gaskets.
Materials:
Plates: AISI 316, AISI 304, Titanium, C2000 and most alloys
Gaskets: NBR, EPDM, FKM and others
Advantages:
* High efficiency due to full countercurrent flow
* Added security against leakage
* Resistant to thermal stress
* Compact and space saving design
* Ideal for handling of aggressive media
* Strong mechanical construction
