Heat exchanger water heater
15 GPM | 415 series
Armstrong International, Inc.
Flo-Rite-Temp Model 415 has 15 GPM capacity with 15PSI steam at a 100°F temperature rise. It 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 415 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, it 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.
