The gas-tight welded plate heat exchanger is intended for processes in which the gas streams must not mix or the temperatures are too high for seals.
Design
The stainless steel plates are fully welded to each other, with no sealing compounds. Each of the four connection sides carries a surrounding frame for the duct connection.
Applications
Typical applications are hot flue gases and process air, for example heat recovery downstream of thermal processes. We size material and plate spacing to your operating data.
Technology
| Type | AEC-300 |

Strengths
- No leakage between the gas streams
- Connection frames for welding or flanging
Limits
- Stainless steel only, heavier than an aluminium block
- Welded and therefore not dismantlable for cleaning
