The Imax plus III offers even greater flexibility of installation and operation with outputs from 95kW to 330kW in a range of six compact floor standing boilers and can be installed in multiple formation to provide even larger outputs if the system requires. High efficiencies are the norm for boilers and the plus III is up to 98% efficient nett (88.3% gross cv) non-condensing, and 106.8% nett (96.2% gross cv) at 30% load.

Even higher efficiencies are achieved at lower temperatures. The fully modulating gas/air design ensures maximum efficiency is maintained down to as low as 11.2kW output. This class-leading figure is achieved even with the largest model as the unique plus III design optimises load matching. The robust cast aluminium heat exchanger comprises of several sections, each flueway or module has its own burner fan, gas valve, ignition and safety controls and after all have modulated down to their combined minimum, modules are switched off to further match a reducing system load. Wasteful on/off cycling is reduced to the absolute minimum with the plus III, and a further benefit is that standby support is built into the design.

Imax plus III boilers are designed for ease of installation and the flue can be positioned to left, right or rear, whilst system and gas connections can be made to left or right of the boiler. All to ensure boiler house siting is as simple and as fast as possible. Naturally the range meets the most stringent European Standards governing safety and performance and is classified as low NOx (Class 5). It is also the quietest boiler of its size at less than 50dBA. The Imax plus III uses advanced microprocessor based controls to operate all electrical functions and provides full commissioning and fault diagnostic displays. Furthermore it takes into account each modules’ operating hours and evens out their usage. Further benefits are that Hours Run Meters and BMS control is built-in as standard, whilst an outside sensor for weather compensation is supplied with each boiler.
