A chimney draught regulator is an essential device designed to stabilize and reduce excessive underpressure in flue pipes, ensuring efficient combustion and optimal heating performance. Excessive draught can result from factors such as an oversized flue cross-sectional area or sudden atmospheric changes like gusts of wind. Uncontrolled draught leads to inefficient fuel combustion, increased heating costs, and potential safety hazards. Implementing a draught regulator helps maintain consistent chimney performance, enhancing both efficiency and safety.

How It Works:

The regulator features a damper that opens when the underpressure exceeds a preset value, introducing additional air into the chimney. This process reduces the underpressure by:

• Cooling the exhaust fumes: Additional air lowers the temperature of the flue gases.

• Increasing flow resistance: The chimney must handle both exhaust and supplementary air, moderating the draught.

Adjustments are made using a knob with a calibrated scale, allowing precise control over the desired underpressure settings.

Darco Draught Regulator Models:

• RCR: Designed for mounting onto pipes with diameters ranging from 120 mm to 200 mm.

• RCO: Available in round diameters of 80 mm and 150 mm.

• RCP: Rectangular model suitable for installation in assembly openings measuring 140 x 150 mm.

• RCW: Intended for installation in chimney inspection openings.

• RCO-EX: Equipped with an explosion safety system that opens the regulator's head in case of a sudden, significant pressure increase, providing a safe escape route for chimney gases.

Installation Options:

• On the flue connecting the stove to the chimney.

• Under the flue.

Benefits of Using a Draught Regulator:

• Fuel Efficiency: Stabilizes chimney draught, leading to optimal fuel combustion and reduced heating costs.

• Safety Enhancement: Prevents issues related to excessive draught, such as overheating and potential damage to the heating system.

• Extended Appliance Lifespan: Maintains appropriate operating conditions, reducing wear and tear on heating appliances.

Incorporating a Darco draught regulator into your chimney system ensures a balanced and efficient operation, adapting to varying environmental conditions and maintaining consistent performance.

Ordering options:

We can customize the draught regulator to suit your specific situation – for example, by manufacturing the necessary adapter, connection, or extension to ensure perfect compatibility with your chimney system and heating appliance.
Important to note: the draught regulator does not increase chimney draught – it stabilizes and maintains it within a specified range. To improve chimney draught, we recommend using chimney deflectors or rotational deflectors, which enhance airflow and reduce pressure for better performance.
