Heat Exchangers

The operating principle of a Plate Heat Exchanger is the same whether assembled as a plate and gasket unit or supplied as a brazed plate unit. In practice both types transfers energy from hot or cold fluid and ensures that the Primary circuit does not mix with the Secondary circuit therefore creating two completely independent separate heating or cooling circuits.

Flow Principle of a Plate Heat Exchanger

Gasketed Plate Heat Exchangers

Built with high quality usually EPDM or Nitrile gaskets which are designed to seal a bank of stainless steel plates together. Plates can easily be removed for cleaning, expansion to increase output or to replace with a new bank within the existing frame reducing high maintenance costs.

Brazed Plate Heat Exchangers

Commonly used in low demand heating and DHW systems or industrial and refrigeration applications. The stainless steel plate and copper brazing construction means that they resistant to corrosion but fixed in as much as the plates are not accessible to expand capacity or replace.

Brazed Plate Heat Exchanger

Plate heat exchangers can be used in many applications such as:
1. DHW generation using the KW from the central heating circuit or similar.
2. Central heating break to extend the life of boilers and heating equipment by creating two separate circuits, this is especially common when installing new expensive equipment into an old system.
3. Process heating and cooling of water, oil, etc.
4. Swimming pools

Please see the technical pages and price list for the standard design DHW and Central Heating plate heat exchangers and please contact our helpful sales office at sales@aelheating.com should you want to discuss or require a design and quotation for a non-standard unit.
