Digital-Flo® Boiler Water PHE 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.
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 with >160°F (71°C) and <160°F (71°C) models. SAGE® performance software monitors, records, and documents data as a critical component of a Water Safety Management Plan. SAGE® works seamlessly with several building automation system protocols, or users can purchase a subscription to use SAGE® on a mobile device.
