Flo-Rite-Temp Model 535DW
Description
Flo-Rite-Temp Model 535DW Instantaneous Steam/Water Heater features a 5″ diameter shell.
Flo-Rite-Temp Model 535DW has 35 GPM capacity with 15PSI steam at a 100°F temperature rise.
The Flo-Rite-Temp Model 535DW 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 535DW is well suited for all hot water applications where steam is available and plumbing codes or safety requirements prevent the heating medium and the portable water supply from being cross-contaminated.
The Flo-Rite-Temp 535DW Instantaneous Steam/Water Heater has 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 535DW 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 535DW 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.

The differential pressure diaphragm within the mixing unit rapidly responds to a change in system demand and significantly reduces the lag times typically associated with feed back/modulating steam control valve systems.
The Flo-Rite-Temp 535DW mixing unit’s diaphragm actuated design can be described as “failure safe” because in the event of a diaphragm failure the mixing unit will fail with a cold bias and will not allow hot water to exit the heat exchanger.
Capable of controlling outlet temperatures +/-4°F, this principal of operation offers the additional relevant benefit of reducing the waterborne bacterial content of the water during the overheating process. In addition, with no water storage requirement, Flo-Rite-Temp 535DW water heaters are a sensible selection as a component of a broader system design initiative for Legionella risk reduction.
Non modulating constant steam pressure ensures condensate drainage and removes the potential for water hammer damage and corrosion. There is no steam control valve to maintain and typically no supplemental condensate return equipment required.
