Water Temperature Control—Recirculation Systems—Digital | The Brain® DRV80RBS

Description

The Brain® DRV80RBS

DRV80RBS Digital Recirculation Valve (DRV), with BrainScan® – hot
water monitoring control module, designed specifically to be the primary
water temperature controller in a continuously pumped circulating hot
water system. DRV80R is supplied with a recirculation return manifold as
shown.

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

  • +/-2°F water temperature control at points of use 25’ 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
