Flo-Rite-Temp Model 665P-P

Flo-Rite-Temp Model 665 P-P Instantaneous Steam/Water Heater pre-piped single temperature packaged assembly designed for a Non-Recirculating Hot Water System.

Flo-Rite-Temp Model 665 Pre-Piped (P-P) Single Temperature Systems are fully assembled and include the following installation components:

Steam Trap
Air Vent
Thermometers
CIP Connection Port
Flow Control/Isolation Valves

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

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

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

Flo-Rite-Temp Model 665P-P 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 665P-P 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 665P-P 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.
