Unimat Heating Boiler UT-L

The boiler type UT-L is an ideal solution for central heating systems of local heating supply with a diverse application profile.

At a glance
  • Three-pass boiler for a medium to high heat demand of 650 to 25,000 kW and up to 16 bar
  • Standard efficiency without flue gas heat exchanger up to 95% and up to 105% with condensing heat exchanger
  • Approved for low return flow temperatures from 50 °C and temperature spread up to 50 K
  • Versatile design for use with different fuel types and as a multi-fuel firing unit (oil, gas, biogas, hydrogen)
  • Smoke tube passes free of disruptive flow components
  • No minimum burner load level for water removal on the flue gas side
  • The Unimat 3-pass design has proven its worth thousands of times in practical applications. The Unimat heating boiler is offered in various sizes and can also be used in a pooled-output multi-boiler system.
  • The UT-L is used particularly readily in hospitals, homes, office buildings, residential complexes as well as throughout all sectors of industry. Its high level of flexibility makes the UT-L ideally suitable for use as a reserve and peak load boiler at heating power stations and combined heat and power plants.
  • The continuous flame tube ends in an inner water-flushed flue gas reversing chamber, which leads into the first smoke tube. Both the first and second smoke tubes are free from flow fittings. The highly functional round design ensures optimal pressure resilience. Furnace, water chamber volume and radiant and convective heating surfaces are perfectly dimensioned and matched to one another.
  • The boiler front door is fully hinged, with hinges on the right or left as desired. The entire cross section of the boiler is freely accessible. This makes maintenance, cleaning and inspection easy. The high quality mineral wool matting insulation covering the entire boiler body and the special thermally insulating materials in the front door keep radiant heat loss at negligible levels. If desired the heat source can be supplied ex works with an integrated flue gas or condensing heat exchanger.

The UT-L heating boiler is supplied as a fully operational unit including equipment. This high-quality equipment includes the boiler pressure vessel, burner unit, flue gas or condensing heat exchanger, and the control and safety technology, which comes ready-connected to the integrated terminal box.
