THE PROBLEM
Unfavourable weather conditions, inappropriate positioning of the chimney, a cold flue gas system when starting combustion or an incorrectly designed flue gas system can cause draught problems in the chimney. This means that the flue gas is not evacuated properly which negatively affects the operation safety of the flue gas system and the fireplace.
THE SOLUTION
If the natural draught is too weak, the chimney fan INJEKT ensures a steady and optimal draught in the chimney. Flue gas systems and chimneys have to be designed in a way that always ensures the negative pressure which is necessary for a safe flue gas evacuation. This makes the INJEKT a safety-relevant component that allows technical approval in case of draught problems.
THE OPERATING MODE
The INJEKT chimney fan is mounted on the chimney outlet and creates a safe draught in the chimney through its electric fan. A special aspect of the INJEKT is the external technology. The INJEKT uses stream dynamics to place all mechanical and electric components outside the cross-section of the chimney. This means that there are no installations in the flue gas path that may narrow the cross-section. As a result there are four major advantages:
1. The cross-section is always freely accessible for the chimney sweep.
2.The fan and electric components have no contact with aggressive and hot flue gasses. This means that the chimney fan needs little maintenance.
3.The cross-section of the chimney is always free - even during power failures.
4. If the natural chimney draught is sufficient and the INJEKT is not needed, it can be switched off. There no risk of damage to the INJEKT. This also saves energy.
APPLICATIONSThe chimney fan INJEKT of Kutzner + Weber is especially suited for draught-sensitive solid fuels, e.g.: wood, pellets, wood chips, etc. In combination with the KW stove regulator it is an effective component within the regulation systems to decrease emissions and increase operation safety. In the case of oil and gas fireplaces, the INJEKT chimney fan can solve draught problems caused by technical difficulties or weather conditions. Please contact our sales engineers for further information.
THE CONTROLThe torque of the INJEKT chimney fan is continuously variable. This allows for individually creating the necessary draught (e.g. high draught for heating up, low draught for glow).
INSTALLATIONDue to the compact dimensions as well as the light weight it can easily be installed on the outlet of chimneys and all conventional and metallic flue gas systems.
