Recirculating Hot Water Systems

Double Wall Pre-Piped Single Temperature (DWP-PR)

Flo-Rite-Temp Instantaneous Steam/Water Heater for Recirculating Hot Water Systems feature four heat exchanger options offered as pre-piped single temperature packaged assemblies.

Flo-Rite-Temp Double Wall (DW) Pre-Piped (P-PR) Single Temperature Systems are fully assembled and include the following installation components:

• Steam Trap
• Air Vent
• Thermometers
• CIP Connection Port
• Flow Control/Isolation Valves
• Thermostatic Diverting Valve

Ideal for both new construction and retrofit installation within an existing building infrastructure. Flo-Rite-Temp Double Wall (DW) Pre-Piped (P-PR) Single Temperature Systems are designed to fit through a standard 32" doorway (Model 8120 36" doorway).

The DW (double wall) version of the Flo-Rite-Temp instantaneous water heater uses a double-wall tube to provide positive separation of the steam and water in the heat exchanger. The area between the walls of the tubes vents to atmosphere so you can detect tube failure without cross-contaminating either the steam or water. The Flo-Rite-Temp DW is well suited for all hot water applications where steam is available and plumbing codes or safety requirements prevent the heating medium and the potable water supply from being cross-contaminated.

Armstrong Flo-Rite-Temp Instantaneous Steam/Water Heater pre-piped packages are available in 58 standard configurations.
