L-Line Brazed Plate Heat Exchangers

Designed for Maximum Performance

Brazed plate heat exchangers consist of stainless steel plate plates, which have embossed chevron patterns. The plates are turned 180° to each other, causing the plate ridges to intersect, and creating a lattice of intersecting channels. The fluids can flow in counter-current or co-current way.

Special corrugation patterns promote high turbulence flow. Turbulence dramatically improves heat transfer rates and reduces the amount of deposits inside the unit.

Double Wall Brazed Plate Heat Exchangers
The design of the double wall brazed plate heat exchanger reduces the risk of 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 will flow into the air gap and escape out of the heat exchanger, enabling visual detection of the leak.

Advantages of Double Wall Brazed Plate Heat Exchangers

  • Visual leak detection
  • Reduces risk of fluid cross-contamination
  • High thermal efficiency
  • Compact design, small footprint
