High level of efficiency for reduced operating costs

The UNIMAT hot water boiler UT-H is a shell boiler with one flame tube, built in three-pass design. While
flue gases flow through the flame tube and smoke tubes, heat is transferred to the water that surrounds
them. The flame tube, the internal rear wetback flue gas reversing chamber as well as the first and second
smoke tube passes, are all arranged for optimum flow within the horizontal cylindrical pressure vessel. A
flue gas heat exchanger from our modular product range can be used for heat recovery.
 High level of efficiency due to three-pass technology and integrated flue gas heat exchanger
 Effective thermal insulation concept for minimised heat radiation
 Up to 93 % boiler efficiency without flue gas heat exchanger, up to 96 % boiler efficiency with flue
gas heat exchanger and up to 105 % with condensing heat exchanger
 Pollutant-reduced combustion thanks to the use of highly developed firing systems and careful matching
of the best boiler and burner combination
 Flexible and efficient use: for heating and hot water supply in public buildings, in commercial and industrial
companies and as base load, peak load and back-up boilers at district heating plants

User-friendly operating concept
 Intuitive boiler control on PLC basis with very high
transparency of operating data
 Prepared for connection to automation systems
 Compatible with the remote maintenance system
MEC Remote
