Three smoke passes (pressurized combustion – low NOx), with double furnace at passing flame with wet back. This structure is coming from the combination of two boiler bodies TRISPACE, so that diving the capacity on two furnaces it is improved the flexibility of use and it is increased the seasonal efficiency.

By using two-stage burners there is the possibility to work with four power runnings, therefore up to the 25% of the nominal capacity, reducing in such way the efficiency losses caused from the intermittent working and also reducing the noise. Suitable to work with gas, LPG, light oil and heavy oil.
