Gasketed
Semi-Welded Plate Heat Exchanger
One side welded for aggressive media, one side open for service.
Plate pairs are laser-welded into cassettes and sealed to each other with gaskets. The welded channel carries the aggressive or refrigerant medium; the gasketed channel stays openable for cleaning. The standard answer for ammonia and for media that attack elastomers.
Chosen for
- Refrigerants, including ammonia
- Media aggressive to gaskets
- Duties needing service access on one side only
- Titanium plates for brine and chloride service
Every heat exchanger we supply is hydraulically tested before despatch, both circuits under pressure together at the test pressures stated on its data sheet. The unit passes only if it holds that pressure without a drop, which is what demonstrates the whole assembly is leak-tight.
The circuits are also tested against each other, one pressurised and the other watched, so a leak between the two media would show. A copy of the test certificate is available on request.
