Imax Plus III

The Imax plus III offers greater flexibility of installation and operation with outputs from 95kW to 330kW in a range of six compact floor standing boilers. The range can be installed in multiple formation to provide even larger outputs if the system requires.

The fully modulating gas/air design ensures maximum efficiency is maintained down to as low as 11.2kW output, achieved even with the largest model as the unique design optimises load matching.

Each boiler comprises several sections, each flueway or module having its own burner, fan, gas valve, ignition and safety controls. As system load decreases the boiler modulates down to the combined minimum. As load further decreases modules are switched off to further match the reducing load. Wasteful boiler cycling is minimised whilst stand-by back up is built into the design.

The range is designed for ease of installation ensuring boiler house siting is as simple and as fast as possible. The Imax plus III is also the quietest boiler of its size at less than 50dBA. Naturally the range is NOx class 5.

Advanced microprocessor based controls are used to operate all electrical functions and provide full commissioning and fault diagnostic displays.

The units also include Hours Run Meters and BMS control built-in, along with weather compensation supplied as standard.
