Flo-Rite-Temp Model 665DWP-PTW-DMC1

Flo-Rite-Temp Model 665 DWP-PTW-DMC1 Instantaneous Steam/Water Heater pre-piped tempered water packaged assembly designed for Recirculating Hot Water Systems.

Flo-Rite-Temp Model 665DWP-PTW-DMC1 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 665DWP-PTW-DMC1 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 665 Double Wall (DW) Pre-Piped (P-P) Tempered Water (TW) Digital Mixing Center (DMC1) Systems are fully assembled and include the following installation components:

Steam Trap
Air Vent
Thermometers
CIP Connection Port
Flow Control/Isolation Valves
DRV80 Digital Recirculating Valve "The Brain" (DMC1)

Ideal for both new construction and retrofit installation within an existing building infrastructure. Flo-Rite-Temp 665DWP-PTW-DMC1 is designed to fit through a standard 32" doorway.

Flo-Rite-Temp Model 665DWP-PTW-DMC1 Instantaneous Steam/Water Heater features a 6" diameter shell and a non-helical straight internal tube bundle with end cap.

Flo-Rite-Temp Model 665DWP-PTW-DMC1 has 65 GPM capacity with 15PSI steam at a 100°F temperature rise.

Flo-Rite-Temp Model 665DWP-PTW-DMC1 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 665DWP-PTW-DMC1 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 665DWP-PTW-DMC1 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 Brain Model DMC1 integrates with the Flo-Rite-Temp Model 665DWP-PTW Water Heater to offer a two temperature system option, +/-2°F "digital" water temperature control and BAS/LAN connectivity.
