Cox Geelen


CoxDRY® is a ventilation air supply and outlet system for heat recovery units. Heat recovery is a method for recovering heat from exhaust air. This heat is used to pre-heat incoming ventilation air.

The range consists of various types of roof terminals, wall terminals and hoses. The complete system is available in the diameters Ø 160, 180 and 200 mm.



Since we spend most of our time indoors, the need for fresh and clean air in our homes is one of the basic requirements for our wellbeing. 
Cox Geelen, ventilation specialist, helps you to achieve the best out of your ventilation system, ensuring a healthy indoor climate. Among the most energy efficient ventilation systems are the balanced ventilation systems with heat exchanger. 

As you can see, we offer a wide range of products labelled as CoxDRY® for suppling Heat Recovery units with fresh air and expel their dirty air. The CoxDRY® range of intake and exhaust air systems is a critical part of every ventilation system, as it effects both energy efficiency, sound comfort and planning reliability at the same time. 

Please contact us for our range of roof and wall terminals for natural ventilation (NV) and for non-balanced or exhaust mechanical ventilation (MV).

  • Thermo-insulating coating in netted and closed-cell of polyethylene foam.
  • Embedded steel wire helix.
  • Thermo-insulating covering in polyester fibre (25mm – 16 kg/m3).
  • Outer aluminized polyolefin protection (flame retardant).
  • Is patented.
  • The assembly of materials for the construction of the flexible hose does not require the use of chemical glues or adhesives.
  • The airflow of sections remains unchanged, even in the curves, and allows to keep unvaried the pressure drop of the project.


  • Fast assembly time.
  • Few parts.
  • Low resistance.
  • 0,66 m2K/W insulation.


CoxDRY® Ventilation ‘flat’ roof terminal for pitched roof

This flat terminal can be placed inconspicuously between the roof tiles and takes up a little space. 

Solar panels

These CoxDRY® Heat Recovery ventilation roof terminals are available in Ø 160, 180
and 200 mm.

Further specifications
The flat roof terminals are powder coated in the colour RAL 9005 matt black and RAL 8023 matt terracotta.
