Flue Gas Dampers

Flue gas dampers are installed in the connection pipe between a boiler and the chimney and close the flue gas path, if the chimney is no longer in use. The flow safeguard prevents the cooling down of the heat generator and the installation room, which helps to save energy. In addition, they prevent a possible influx of exhaust gases of other fireplaces connected with the chimney, for example in the cascade system and have the effect of an exhaust gas silencer if there are more than one fireplace connected with the chimney.

Stainless steel or black steel flue gas dampers made by Jeremias are used in combined heat and power plants, emergency power systems, exhaust air technologies and in overpressure operation engines.

Flue Gas Duct

Flue gas ducts are made for a robust and safe connection solution between the boiler-/engine outlet and the chimney entrance. Depending on the requirement of the service life and the different compression ratio, they can be produced as a plug –in system, completely welded or as a flange system. The planning in this sector for compensators, flue gas dampers, structural steel supports is done by our experienced project leaders. In this way it is possible to offer you professionalism, knowledge, and absolute guaranty.

FS-RM - Freestanding Chimney Systems

If you are looking for a flexible solution for your chimney the FS-RM system is the best system for you.  The combination of a steel (chimney) support mast and stainless steel chimney elements offers you the possibility to customize your chimney at any time as per your new requirements.  Hence it is now possible to achieve heights of up to 30 meters with stainless steel elements.

FSA - Freestanding Chimney Systems

Free-standing, double wall chimney with a supporting couter wall and a non-expanding inner pipe for exhaust gases.  The FSA system offers flexibility and large heights.

FSA-X - Freestanding Chimney Systems

In comparison to FSA, the FSA-X has multiple inner pipes.  The “X” stands for the number of inner pipes. This facilitates to connect two or more heat producers to the same outer chimney, hence economical.

FSB - Freestanding Chimney Systems
