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

GEOTHERM ® WGB (V) series boilers are manufactured with three temperature schedules 70-95 °C; 70-110 °C; 70-150 °C.

GEOTHERM ® WGB (V) series boilers are produced with a capacity from 35 to 68.9 MW.

The fundamental difference between the boilers of the GEOTHERM ® SPI (M) series from the boilers of the GEOTHERM WB(P); GEOTHERM MEDIA; GEOTHERM WEB(3P) series is that the boiler pipe system has a vertical design. The main advantage of boilers of this series is that at high power boilers take up little space when installed on the foundation. This makes it possible to build high-capacity boilers on relatively small areas.

Main components of GEOTHERM ® WGB (V) 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.

GEOTHERM WGB (V) 68.9 hot water boiler is the most powerful in the geotherm series. The gas-tight boiler works with burners from leading european and russian manufacturers. The pipe system and burners are arranged vertically.

Advantages of the boiler geotherm series:

High efficiency

Gas-tight tube

Low NOx emissions

Quick launch

Reliable and simple performance

Modern design

Possibility to use boilers in open heating systems

Package supply

Wide size range from 0,25 to 68,9 mw

Application of boilers with burners from leading European and Russian manufacturers

Low hydraulic resistance

Simplified repairs
