Renovation solution for communal flue systems

CoxHYBRID® CFS PP


Are you looking for a quick, easy and affordable solution for the renovation of an old gas flue shared system chimney in a multi-storey building? To make it suitable for the connection of multiple natural gas condensing boilers, then look no further.

The replacement of gas appliances on old duct shared system chimneys is becoming increasingly difficult. The cost of re-engineering an old chimney system to accommodate high efficiency condensing appliances is often expensive. The new CoxHYBRID® CFS PP system offers the perfect solution.
CoxHYBRID® CFS PP is a revolutionary positive pressure Communal Flue System (CFS), which has been developed by the Cox Geelen’s Research & Development Centre with the close cooperation of installers from the home and export markets. This innovative solution enables you to adapt old shared system chimneys in multistorey buildings quickly and easily for connection of modern high efficiency condensing boilers. The new CoxHYBRID® CFS PP system offers a cost effective renovation solution, without the need for re-work.

Quick • easy • safe


Due to the corrosive environment Polypropylene (PP) and stainless steel are the safest materials to use. The CoxHYBRID® PP CFS system is lightweight and is quick and easy to install. The sections used to create the replacement chimney, have flexibility built-in providing the adjustment needed to accommodate different floor to floor heights, so eliminating the need for cutting on site. The major issue with any retrofit is the management of the condensate produced by modern high efficiency appliances. There is no problem if there is no facility to provide a drain facility for the condensate. The condensate can be easily discharged through the flue pipe to the boiler. A complete CoxHYBRID® CFS PP stack is made up only of a few standard parts, namely a roof terminal, a roof mounting plate, a number of repeating pipe sections and a base unit.

CoxHYBRID® Fire-rated wall plates


Recently the CoxHYBRID® program has been further extended. Cox Geelen introduced new round fireproof wall plates with integrated fire seal. These innovative wall plates are designed for connection to flexible and concentric flue material. A fixed gradiant of 3° was included in the design for drainage of condensate towards the heating appliance. These revolutionary wall plates ensure a fire and carbon monoxide safe situation in the house. 
Cox Geelen's wall plates are flame-proof as well as heat insulating, a must-have for flue gas and chimney renovations! By installing a fire-resistant wall plate over the opening in the shaft, the flue gas discharge and air supply are restored to at least the same fire resistance requirements as the shaft wall itself.

Application

The CoxHYBRID® CFS PP system is designed for the renovation of old gas flue ducts (Shared System Chimneys) in multi-storey residential buildings enabling the connection of suitable gas-fired condensing appliances (T120). As no major engineering re-work is necessary in the building the residents experience minimum disruption during the installation.

The following Shared System Chimneys originally designed for dry flue gases (non-condensing SE boilers) can be renovated with CoxHYBRID®:
  • Spiral wrap metal seamed chimneys.
  • Architectural masonry chimneys.
  • Shared structural chimneys, for example Shunt, SE-Duct, U-Duct.
  • Aluminium and Stainless Steel CFS systems.
Besides being used in renovation projects, the CoxHYBRID® CFS PP system can also easily be used as a single-walled positive pressure CFS system in new housing developments.

Diameter

The CoxHYBRID® CFS PP system is available in Ø 130 mm and Ø 180 mm.

Approval

CE marked according to EN 14471.

Recyclable

At the end of its life span the CoxHYBRID® CFS PP system can be entirely recycled. The use of recyclable plastics contributes to a more sustainable and greener environment.
