Double Wall Brazed Plate L-Line Heat Exchangers

L-Line DW Double Wall Heat Exchangers

Double Wall Brazed Plate Heat Exchangers - With visual leak detection


The design of the double wall brazed plate heat exchanger prevents cross contamination of fluid streams if there is an internal leak within the unit.

Two stainless steel plate walls separate the fluid streams, with an air gap in between. In the event of a leak, the affected fluid flows into the air gap and escapes out of the heat exchanger unit, enabling visual detection of the leak.

Special corrugation plate patterns within the heat exchanger promote highly turbulent flow. Turbulance dramatically improves heat transfer rates and reduces the amount of deposits inside the unit
