- The Unimat UT-H is a shell boiler with one flame tube, built in a 3-pass design. Flue gases flow through the flame tube and smoke tubes on the inside and boiler water flows around them on the outside. The flame tube, internal water-flushed rear flue gas reversing chamber, first smoke tube and second smoke tube are all arranged for optimum flow within the cylindrical pressure vessel.
- The main areas of use of the UT-H hot water boiler are local and district heating generation, all sectors of business, the processing industry, heat suppliers and public facilities. These boilers are also used as base load, peak load and reserve heating boilers at district heating plants.
