The Swedish based hydronics solutions specialist, ESBE, has introduced new high specification Series GMB600 distribution units for managing zoned heating. The ‘Flexbox’ offers UK installers greater efficiency as well as flexibility when installing boilers or renewable heating systems, in both domestic and commercial premises where there are two or three heating zones.
The compact boxes can be surface mounted or recessed into a wall, for which a blanking strip is available. When mounted inside the wall a cover strip is available as an option to cover the transition between the box and the wall or other substrate, while the design of the air vent valve allows for 360° orientation. Intended for DN20 compatibility, there are two incoming connection ports (left and right) on the supply side, though one is plugged to avoid unnecessary piping. The proportions of the Flexbox also allow for either uninsulated GxA394 or insulated GxA311 circulation units to be installed, along with shut off valves. GRA394 has a 3-way rotary mixing valve with progressive characteristic and comes with a knob for manual adjustments, but can be equipped with the preferred actuator (ARA) or controller (CRx).
