They are monobloc boilers at three smoke passes (pressurized combustion – Low NOx) with wide furnace with passing flame and with wet bottom, suitable for working with liquid and gaseous fuels. Geometric structure (tube nest over the combustion chamber) that allows to reduce the width; in such way is easier the introduction in the heating plants with narrow entry passages and with reduced dimensions.

Through use of special turbulators of new conception, built in STAINLESS STEEL that increase the smoke turbulence, they can be considered high efficiency boiler superior to 93%.
