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.
Innovative digital technology resists “temperature creep” during periods of zero system demand which eliminates the requirement for manual throttling valves, supplementary RTD or a temperature actuated switch to control the pump.
Energy efficient, low temperature loss systems can be implemented by the ability of The Brain® to operate with a system differential of just 1°F below set point.
User safety and overall system health is maintained by a series of programmable temperature alerts, onboard operational self-diagnostics, and a thermal disinfection option.
The Brain® is equipped with a recirculation manifold assembly.
