Digital Recirculating Valve (DRV) and Mixing Centers (DMC)

Digital

Water Temperature Control - Digital features a Digital Recirculating Valve (DRV) and Digital Mixing Centers specifically designed for use in a pumped recirculating hot water system.

“Out of the Box” Solution

Model DRV 80 is a single installer/operator programmable "out of the box" solution for systems which experience diverse user draw-off between 0 to 150 GPM.

"Plug and Play" Solution

Model DRV 80R is a single installer/operator programmable "Plug and Play" solution for systems which experience diverse user draw-off between 0 to 150 GPM. Model DRV 80R includes a recirculation system return manifold assembly.

"Packaged" Solutions

Model DRV 80 based Digital Mixing Center (DMC). Model DMC 1 features a single DRV 80 pre-piped and pressure tested complete with isolation valves, strainers, mixed return flow indicator, check valves, thermometers and an optionally selected system circulating pump for systems which experience diverse user draw-off from 0 to 150 GPM.

Model DMC 2 features two DRV 80s plumbed in parallel, pre-piped, pressure tested with system accessory items as above for systems which experience diverse user draw-off from 0 to 300 GPM.

Remote Control, System Monitoring, System Interrogation and Data Logging

Model DRV 80 and Armstrong Packaged assemblies which feature Model DRV 80 (DRV 80R, DMC1, DMC2 etc) are provided as standard with an integral Mixed Outlet Water sensor and Remote Set Point Adjustment capability for "plug and play" system communication via PC , LAN or resident Building Automation System.

Model DRV 80 offers an integral relay point for connection to a selected accessory component such as a pump on/off switch, to activate/deactivate a solenoid or to enable an audible alarm etc.

Model DRV 80 is supplied as standard with integral Hot Water & Cold Water/System Return Water sensors and a serial connection data port which enables communication to third party system hardware via an accessory component called BrainScan™.

BrainScan™

BrainScan™ is an optionally selected external network adapter console from Armstrong complete with custom tailored software. BrainScan connects to the integral serial connection data port on DRV 80 and enables a direct onward connection to Building Automation Systems which utilize LONWORKS & BACNET protocols, a communication capability with other Building Automation Systems which connect via an RS485 port, an Ethernet port for web access OR an RS422 port for connection to an optionally available Wi-Fi/modem module.
