Pro

Fireplace cassettes
Made to measure with integrated control
We offer our tailor-made chimney cassettes in a wide range of shapes and sizes so that they can be perfectly adapted to any open fireplace. The efficient flue gas routing noticeably reduces flue gas temperatures and heat losses. Thanks to the optimized flue gas routing, significantly more pollutants are burned than with open fireplaces, which considerably increases efficiency. The integrated, currentless automatic combustion air system ensures particularly efficient combustion and at the same time enables effortless operation with reduced wood consumption. Cleaning is also uncomplicated: The removable ash box makes it easy to empty.
Select the right size
The ideal product for every installation situation: our fireplace cassettes are available in seven different versions. Whether as a one-, two- or three-sided version, with round glass or in a curved shape - we offer the right model for every taste.

Special features and details

Improved air flow
For optimum oxygen dosing via the secondary air, the primary air is automatically switched off as soon as the air control lever is 20% closed. This results in a beautiful and efficient burn.

Felt seals
Absorbs moisture from the combustion air and releases it again without cracking. The seal is characterized by an unprecedented longevity.
+ Adjustable feet on the combustion chamber
- Primary air infinitely adjustable via air control lever
- Combustion air Ø 125 mm
- Combustion air connection can be rotated by 90 degrees
- Fixed flue gas connection Ø 150 mm
- Vermiculite baffle plate (hinged for retrofitting) ensures improved heat output

Large smoke collector
Thanks to the generous space above the baffle plate, the amount of smoke escaping into the combustion chamber or living area is greatly reduced. Some of the efficiency-enhancing deflectors inside the smoke collector can optionally be replaced with catalytic converter plates.

Optional axial fans
Two axial fans accelerate the convection air that has been heated up and re-emerges above the combustion chamber. The fans can transport up to 80 m³/h of air.

Welser profile frame
The sturdy door frame guarantees durability and safety. The plug-in door seals based on the Welser profile enable easy maintenance and quick replacement of the viewing panel. Even when servicing is required, affected parts can be replaced in no time at all.
