Flo-Rite-Temp Pre-Piped for Digital Control of Recirculating HW 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 exclusively for continuously recirculated hot water systems, the piping assembly includes The Brain which improves system performance and safety by delivering a consistent pre-set temperature to the points of use.
User safety and overall system health is maintained by a series of programmable temperature alerts, onboard operational self-diagnostics, and a thermal disinfection option.
Flo-Rite-Temp Pre-Piped for Digital Control of Recirculating HW 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.
