The Digital-Flo Semi Instantaneous Steam/Water Heater is a pre-piped packaged water heating solution with an integral Brain® Digital Recirculation Valve (DRV) for hot water system water temperature control.
Engineered exclusively for continuously recirculated hot water systems, The Brain improves system performance and safety by delivering a consistent pre-set temperature to the points of use.
Water is heated above Legionella survival temperatures on every recirculation cycle. A separate steam control valve is not required. User safety and overall system health is maintained by a series of programmable temperature alerts, onboard operational self-diagnostics, and a thermal disinfection option.
Digital-Flo is 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.
