SWEP B16 - 30 Plate Double Wall Vented Heat Exchanger

SWEP B16 double wall vented heat exchangers provide superior performance while complying with strict code requirements to prevent contamination.  The double wall design provides a small air gap between the solar heat transfer fluid and the domestic water side of the heating system.  In the event of a rupture on either the solar side, or the domestic water side the air gap provides a non-pressurized escape path for the fluid.  This eliminates potential concerns related to domestic water contamination when using single wall heat exchangers.  In addition to added safety to the domestic water system, the double wall heat exchanger design prevents domestic water from entering the collector loop which has the potential to cause freeze damage in cold climates.
