The Unical Modulex range of free-standing condensing boilers uses cast aluminium technology to deliver outputs from 96 to 894kW with maximum energy efficiency and minimum weight.

The pre-assembled floor-standing units combine flue gas condensing, premixing and modulation to ensure that all installations deliver maximum energy efficiency and minimal environmental impact, including significantly reduced NOx emissions. Each Modulex boiler system is made up of a number of down-firing pre-mix burner units that are pre-assembled on aluminium modules. Boilers will modulate on a cascade down to a minimum output of 12kW for models 100 to 340 and 22kW for models 440 to 900.

Modulex boilers are supplied with the E8 Regulator. This is extremely versatile, easy to program and can meet both central heating and hot water needs while optimising energy savings.

• Modular boiler with multiple, down firing, pre-mix burner units to maximise flexibility and reliability
• Turn-down ratios of up to 40:1 to match boiler output to heating load
• Manual switch allows boiler to run at 50% of nominal output in the event of boiler controls failure, ensuring security of heat generation
• Seasonal efficiency of up to 97.1% gives compliance with ADL2A and ADL2B of Part L 2006
• Qualified for the Energy Technology List
