Brazed Plate Heat Exchangers


APV standard 'P' types offer AISI 316 stainless steel plates and connections with copper brazing. The units are rated for 450 psig/31 bar operating pressure with a maximum temperature of 437°F/225°C. P series are typically installed with a Y-strainer to protect the unit from debris, while custom insulation kits minimize ambient losses.

A principal system design includes a primary heat source (i.e. boiler) and a secondary loop such as snowmelt or radiant circuit. Sanitary instant hot water can also be produced from this system with the use of appropriate controls. Due to the low internal volume of the brazed exchanger, instant hot water is possible in many cases eliminating the need for thermal storage tanks.

Brazed Plate Heat Exchanger Features:

Inherent of their turbulent flow, brazed plate heat exchangers resist particulate fouling and scaling. Units can be cleaned using a phosphoric or citrus acid solution circulated in reverse at 1.5 times the normal fluid flow rate. Replacing bulky shell and tube, coiled, coaxial and other less efficient heat exchangers, brazed plates have allowed system designers not only to think outside the box, but also to make the box smaller - pushing the boundaries of system design.
