Gasketed Double-Wall Plate Heat Exchangers

Supplier: Alfa Laval

Protection against intermixing

Price Guide: POA

The double-wall heat exchanger is designed for applications where a hostile reaction can occur if the two media mix, or when product contamination must be avoided.

Replaces single plate

Normally, double plates replace the single plate that separates the two media from each other.

Sealed by gaskets

Conventional gaskets seal the channels formed by the double plates.

Extra protection

In the unlikely event of leakage, the media is easily visible on the outside of the heat exchanger. A hole in one of the double plates results in leakage between them. A gasket defect causes an external leak either directly from the peripheral gaskets or between the plates at the site of the failure.

Typical uses are:

  • Tap water heating
  • Lubricating oil cooling
  • Transformer oil cooling
  • Heating and Cooling of pharmaceuticals
