Atag’s rig for cascade boiler installations
An installation rig for Atag Heating’s Q Series condensing boilers enables up to three boilers to be installed in cascade operation. The rig is only 1.5 m high and enables boilers to be installed in a variety of configurations. Q Series boilers modulate down to 16% of full output and are up to 109.3% efficient. These rigs offer outputs from 9 to 172 kW.
This cascade system comes with a full hydraulic system to suit most installation requirements — including all pipework, isolation and non-return valves, as well as gas line and low-velocity header.
The system can also be used as a separate solution to provide DHW via an indirect hot-water cylinder.
