The Brain® Model DMC50-50

Digital Mixing Center including two DRV50 supplied with all requisite installation components for systems which experience diverse draw-off between 0 -165 GPM* or require DRV redundancy - 3” flanged connections.

DMC50-50 is a fully Digital Mixing Center (DMC) designed specifically to be the primary water temperature controller in a continuously pumped circulating hot water system.

Digital technology provides enhanced water temperature control accuracy which resists zero system demand “Temperature Creep” without the use of a manual throttling valve or a temperature activated pump shut-off device (aquastat).

Operational Specifications (DRV50)

  • +/-2°F water temperature control at points of use 25’ (7.7 m) downstream during demand

  • +/-2°F water temperature control at the DRV during zero system demand “idling” periods

  • 2°F minimum valve inlet to outlet temperature requirement (system recirculation temperature loss)

  • Automatic shutoff of hot water flow upon cold water inlet supply failure

  • Automatic shutoff of hot water flow in the event of a power failure

  • Programmable set point range of 81-158°F (27-70°C)

  • Programmable thermal disinfection mode

  • Programmable 1st level hi/lo temp alarm display

  • Programmable temperature error level for safety shutdown
