GEOTHERM ® WGB (3P) series boilers are designed to produce hot water. Boilers are focused on heat supply of industrial and domestic facilities.

GEOTHERM ® WGB (3P) series boilers are produced with three temperature schedules 70-95 °C; 70-110 °C; 70-150 °C.

Boilers of the GEOTHERM ® WGB (3P) series are produced with a capacity of 0.25 to 15 MW.

The fundamental difference between the boilers of the GEOTHERM ® WGB (3P) series from the boilers of the GEOTHERM WGB(P); GEOTHERM WMB; GEOTHERM WGB(V) series is that the exhaust gases after burning the torch of the burner unfold in the furnace, pass through the fiston, unfold again and pass through the convective surface. The main advantage of boilers of this series is that they can be used to replace old equipment during the reconstruction of boiler houses because boilers of the GEOTHERM ® WGB (3P) series have a small overall size in length. The small overall size in length is achieved by the fact that the convective surface is located above the boiler furnace, and not behind it as in GEOTHERM ® WGB (P) series boilers.

Main components of GEOTHERM ® WGB (3P) 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.

Hot water boiler GEOTHERM WGB (3P) 1.1 of gas-tight design operates in open and closed heat supply systems, with a heat carrier temperature of up to 110°C.
