Welded
Plate & Block Heat Exchanger
Fully welded block, fully accessible for cleaning.
Also called: Welded block heat exchanger · Block heat exchanger · Plate-and-block heat exchanger
A welded plate block with removable side panels, giving full mechanical access to both sides without a single gasket in the thermal pack. Built for aggressive chemical service where both cleanability and corrosion resistance are required.
Side panels bolted on. Removing them opens both sides of the block for mechanical cleaning.
Chosen for
- Strong acids and aggressive chemicals
- Duties requiring both weld integrity and cleaning access
- Chlor-alkali and fine-chemical 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.
