Flo-Rite-Temp Pre-Piped for Thermostatic Control of Recirculating Hot Water Systems are factory-built water heating packaged solutions inclusive of a shell & tube heat exchanger fitted with an integral control valve for water heating and system temperature control.
The feed forward design instantly determines downstream hot water demand and directs cold water through the heat exchanger. Water is heated above legionella survival temperatures with constant pressure steam and then blended with a proportional amount of cold water to set point temperature.
Engineered specifically for recirculating hot water systems, the piping assembly includes a three-way thermostatic diverting valve.
Flo-Rite-Temp Pre-Piped for Thermostatic Control of Recirculating Hot Water Systems are available with single wall or double wall heat exchangers in 4 standard sizes each with a parallel/redundant option and can be customized to suit.
