The Modulex range of high efficiency condensing boilers from Clyde, an expert in the supply and support of boilers, radiators and heating systems for commercial customers, has increased outputs and now includes two new super size models. The new Modulex M770 and M900 cast aluminium alloy boilers combine exceptional reliability with the output power of multiple boiler systems.

Like the other floor-standing boilers in the Modulex range, Clyde’s new M770 and M900 versions combine flue gas condensing, premix burner technology and modulation to ensure maximum energy efficiency and minimal environmental impact. Mutliple burners in the new models ensure dependable, fail safe operation and eliminate the need to specify standby boilers, thereby reducing installation costs. This also assists compliance with Part L 2006, which requires much closer matching of boiler output to design load with minimal oversizing (maximum 20%) without compromising the need for back-up in the event of equipment failure. Needing only single phase electrical supply and a gas supply pressure of only 20 mbar, these larger models also require no gas booster, resulting in further cost savings.

The boilers also feature an innovative over-ride switch on the boiler’s electronic control system. If the integral boiler control system fails for any reason, this over-ride allows the boiler to continue to operate in a fail-safe mode at 50% load until a service engineer can attend. The radiant burner design provides almost silent combustion, which makes Modulex one of the quietest on the commercial boiler market at less than 50dBA. According to the company’s press release, with this latest expansion, Clyde’s Modulex range now offers eleven models with outputs from 96kW through to 894kW to suit all types and sizes of commercial heating requirements.
