Imax Xtra EL - Floor Standing

The Imax Xtra EL floor standing condensing boiler range features a single heat exchanger and has been specially designed for commercial applications that require larger outputs in a compact package. Available in 320, 395, 470, 545 and 620kW outputs, all Imax Xtra models offer very low NOx Class 6 performance for maximum points on the BREEAM scale and extremely high efficiencies up to 109.8% part load at 30% output. This means that the 320kW and 396kW models are fully compliant with the Energy-related Product (ErP) Directive’s high efficiency requirements, which is applicable to boilers up to 400kW, whilst the models above are compliant with Building Regulations Part L2. Straightforward integration with 0-10v BMS systems is easy; together with volt-free contacts and alarm signals, there is a range of additional kits available for added control, including a modulating sequencer, plant room sensor, outside sensor and optional gateway adaptors to MODBUS, LONWORKS or BACNET.
