ATAG launches range of modular boilers
ATAG Heating’s XL range of commercial boilers comprises three models with outputs of 70, 110 and 140 kW. They can be combined in multiples of up to eight units to give a maximum output of 960 kW. The heat exchanger is of 316 stainless steel to help achieve an efficiency of up to 109.3% (EN677), achieved through seamless upward modulation. NOx emissions are below 30 ppm.
These boilers can be wall- or frame-mounted in line or frame mounted back to back. The maximum output can be achieved in a footprint of just 2.7 m2.
There is a range of flue options, including concentric, twin pipe, conventional and over pressure. Controls include a built-in cascade controller to maintain an even load for each boiler; it can be connected to 0 to 10 V, on/off or Open Therm supplies.
All models include a built-in fully modulating pump with an A energy rating and A-rated components. Hydraulic headers are available in modules from one to eight boilers, with connections for back-to-back installations.
