Double-wall units prevent intermixing of fluids due to a plate failure. Two plates are pressed together to ensure a tight fit to minimize heat transfer losses while maintaining a leak path in case of plate failure.
Plate and Frame heat exchangers use a combination of chevron-style heat transfer plates sequenced between a frame plate and pressure plate. The heat transfer plates have holes at the four corners forming a header that distribute the respective flows to the opposite sides of each plate when the plates align. The fluids are confined to the heat transfer surface of the plate or the port as appropriate with elastomer gaskets.
Materials: 316SS or Titanium plates. Gaskets in Nitrile, EPDM, Viton, high temperature EPDM and high temperature Nitrile. Other materials upon request.
Applications: For close temperature approach of fluids for heat recovery applications. Potable water applications, and pharmaceutical applications and engine cooling.
Features and Benefits:
- Higher surface area to volume ratios than conventional shell and tube heat exchangers
- Superior heat transfer coefficients compared to shell and tube heat exchangers
- Offers “true” countercurrent flow, which maximizes the mean temperature difference between fluids
