DRAUGHT REGULATORS

Darco system

DRAUGHT REGULATORS

Draught regulators are used to stabilize and decrease chimney draught in ventilation, flue and smoke ducts. This device  is to be mounted next to the chimney connection, equipped with a damper with an adjustable weight. The weight is to be regulated to achieve and maintain a certain underpressure ratio.

Chimney draught regulator decreases too high pressure in chimney duct, which:

  • appears despite correct cross-section of a chimney duct,
  • appears if the cross-sectional area of chimney duct is to big;
  • is caused by temporary impact of weather conditions for example strong wind

Device is destined to be mounted:

  • on the connector which connects stove with the chimney
  • over the connector
  • under the connector

DARCO offers chimney draught regulators:

RCO –  Round draught regulators –  are used to stabilize and decrease chimney draught in ventilation, flue and smoke ducts

RCR – Chimney draught regulator mounted on a pipe – diameter from 120 to 200 mm.

RCP – Rectangular draught regulators designed for chimneys with diameters from 100-250 [mm] and height of max. 20 [m]

RCW – Device to be mounted instead of chimney revision doors in the chimney system. To mount the RCW-type draught regulator the RM-DW mounting frame must be installed first

RCO-EX – is equipped with an additional anti-explosion system, which, in case of sudden increase of pressure (for example: sudden combustion or fumes explosion in chimney or chimney connection) opens the forehead, allowing the exhaust fumes to be extracted. This solution prevents chimney or stove from getting damaged in such situation.

USAGE:

  • stabilisation and limitation of chimney draught in the chimney
