GEOTHERM ® WMB series boilers are designed to produce hot water. Boilers are focused on heat supply of industrial and domestic facilities.

GEOTHERM ® WMB series boilers are produced with three temperature schedules 70-95 °C; 70-110 °C; 70-150 °C.

GEOTHERM ® WMB series boilers are produced with a capacity from 0.63 to 35.0 MW.

The fundamental difference between the GEOTHERM ® WMB series boilers and the GEOTHERM WGB(3P); GEOTHERM WGB(P); GEOTHERM WGB(V) series boilers is that an intermediate collector is provided in the pipe system and niches for ash removal are located under the convective part. An intermediate collector is necessary to increase the pitch in the convective surface, this avoids clogging of the convective surface with fuel oil. The niches are designed to remove ash residue that forms on the convective surface during the combustion of fuel oil. The main advantage of boilers of this series is that they can run on fuel oil.

The main components of the GEOTHERM ® WMB series boilers:

  • Collector frame - serves to distribute water flows depending on the hydraulic circuit of the boiler and the connection of the boiler to the external strapping.

  • The convective section is the main part of the boiler pipe system.

  • The support frame serves as the base for the installation of the boiler pipe system.

  • Stiffness belt - serves as a frame to ensure the rigidity of the boiler.

  • The flue duct with an explosive valve - serves as a channel for the discharge of exhaust gases.

The GEOTHERM WMB 7.56 hot water boiler is painted in gray and red corporate colors, which gives the boiler a modern appearance, and a gas-pulse cleaning port is also provided.
