Industrial steam boiler UNIVERSAL U-ND, U-HD

For low to medium steam requirements, boilers are available in the capacity range of 175 to 3200 kg/h.


Industrial steam boiler UNIVERSAL U-ND, U-HD

The U-ND and U-HD boilers combine the advantages of large water volume boiler technology with the efficiency of the flue tube and fire tube system, based on the principle of flame inversion.


The fire tube and the large volume flue tubes are perfectly matched to each other. The boiler is characterize by a very compact design. We offer you the UNIVERSAL steam boiler, which can produce high and low pressure steam.

The large-volume steam boiler impresses with its compact design and its technical and economical features. The large central fire tube ensures perfect combustion. The flue gas tubes centered around the fire tube ensure optimum heat transfer.

 

Thanks to the three-pass system, the flue gases are redirected forward in the fire tube according to the flame reversal principle and then directed into the front reversal chamber to the flue tubes. The hinged front boiler door (left or right) provides convenient access for inspection of the boiler and burner. The high quality mineral wool insulation of the entire boiler body and the special thermal insulation of the front door ensure a reduction of radiation losses.

Our boilers are offered with accessories as fully functional units. The quality standard equipment of these boilers includes the boiler pressure vessel, control and safety technology, burner block, feed pump module, connection box and control cabinet with BCO boiler control.
