Double Wall Plate And Frame Heat Exchanger

The engineered corrugated plate design provides very high heat transfer coefficients resulting in a smaller heat exchanger.

Double wall plate and frame heat exchanger. The plumbing code is very specific in its requirement for double wall with an air gap and leak paths to atmosphere. Referencing the brazed plate heat exchanger table above we would select an sp110y 30 for a single wall application or a sp110dw 30 for a double wall application. Two of the products featured were the double wall plate frame and double wall brazed plate heat exchangers. Brazepak double wall brazed plate heat exchangers offer the highest level of leak protection safety thermal efficiency and durability in a compact low cost unit.

Gaskets act as seals between the plates. Pairs of identical plates are laser welded around the ports. Fluids normally run counter currently through the heat exchanger. We have received many calls regarding these models and michigan and ohio plumbing codes.

Plate and frame heat exchangers use a combination of chevron style heat transfer plates sequenced between a frame plate andread more. 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. Popular heat exchanger type and brands complete unit and heat exchanger spare parts plate and gasket semi welded plate heat exchanger for refrigerant wide gap plate heat exchanger for liquid containing solids particles fibers and viscious materials double wall plate and frame heat exchanger for protection from mixing of the two fluids. Thin corrugated stainless steel plates are vacuum brazed.

Plate and frame heat exchangers use a combination of chevron style heat transfer plates sequenced between a frame plate and pressure plate. Double wall units prevent intermixing of fluids due to a plate failure. Built to last taco pf series plate frame heat exchangers utilize 5mm thick plates for standard designs and 6mm plates for higher pressure design requirements. Taco pf models can be offered with single wall or double wall plates depending on your application requirements.

Once the heat exchanger is known the cv value can be used to find the pressure drop imparted by the heat exchanger for pump selection as well as the hx volume for fluid domain calculations. The gasket is installed in the conventional manner and the welded plate pairs are assembled in a plate pack in the same way as ordinary single plates. 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. The heat transfer area of a gasketed plate heat exchanger consists of a series of corrugated plates assembled between a frame and pressure plates to retain pressure.
