Flo-Rite-Temp Model 535DWP-PR

Flo-Rite-Temp Model 535DWP-PR Instantaneous Steam/Water Heater pre-piped single temperature packaged assembly designed for a Recirculating Hot Water System.

Flo-Rite-Temp Model 535DWP-PR double wall 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 535DWP-PR 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.

Flo-Rite-Temp Model 535 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 535 DWP-PR is designed to fit through a standard 32" doorway.

Flo-Rite-Temp Model 535DWP-PR Instantaneous Steam/Water Heater features a 5" diameter shell and a non-helical straight internal tube bundle with end cap.

Flo-Rite-Temp Model 535DWP-PR has 35 GPM capacity with 15PSI steam at a 100°F temperature rise.

Flo-Rite-Temp Model 535DWP-PR features a unique feed forward design which features a differential pressure diaphragm actuated mixing unit integral to a shell and tube heat exchanger.

The Flo-Rite-Temp Model 535DWP-PR mixing unit manages the water flow through the heat exchanger based upon downstream hot water demand and eliminates the requirement for a modulating steam control valve.

Operating on constant low pressure (2-15PSI) steam, the Flo-Rite-Temp Model 535DWP-PR mixing unit supplies water to the heat exchanger where it is overheated and then returned to the mixing unit for proportional re-mixing with cold water to a pre-set outlet temperature.
