The DUALIS EI watertight concentric duct range, which now extends its field of application to watertight wood pellet (or pellet) boilers, is a perfect illustration of this.
DUALIS EI, a versatile concentric duct
The DUALIS EI range is not unknown since it has already been fitted to gas condensing boilers and sealed oil boilers for many years. The technology used is that of the concentric duct, a "two-in-one" duct making it possible to manage an outgoing air flow (smoke evacuation) and a combustion air inlet for 100% sealed operation.
In 2019, a few improvements will allow the range to extend its playground to wood pellet boilers, thus enhancing its versatility. Here are the adaptations made:
- standardization of the smoke seals to allow the evacuation of smoke up to 250 °;
- creation of a fourth diameter 150/200 dedicated to wood pellet boilers of 30/40 KW;
- design of specific parts to facilitate connection to devices.
DUALIS EI thus becomes the privileged partner of standard non-condensing or low temperature sealed wood pellet boilers and condensing devices.
Several possible configurations, and always customization available
DUALIS EI is easily installed using a simple and perfectly waterproof interlocking system. In new as well as in renovation, it allows installations with vertical or horizontal terminals from the nozzle of the device to the outside of the building.
Note that in the context of a renovation, a replacement of an oil boiler for example, DUALIS EI can also be adapted to a traditional masonry flue. In this case, an adapter kit on flexible tubing for DUALIS EI connection is necessary.
In terms of customization, DUALIS EI is not left out:
- The vertical terminal offers 8 colors in total (including black and brick available from stock).
- The horizontal terminal offers a standard stainless steel finish, it is also available in the RAL color of your choice on request.
Ideal for facilitating the integration of the terminal into its environment.
In response to the Eco-design directive
By thus opening up to the market for airtight wood pellet boilers, DUALIS EI provides a new response to the replacement of inefficient boilers (low temperature boilers) that do not comply with the Eco-design directive, by equipment with very high energy performance. .
Under technical advice (DTA: 14.2 / 12-1821_V2) and CE marked, DUALIS EI was developed with the support of the CÉRIC laboratory, COFRAC approved. The system has been the subject of a series of functional tests to validate all the connections according to the different brands of sealed boilers under technical advice offered on the market.
