Cox Geelen


Under the brand name ECONEXT®, Cox Geelen offers a wide range of roof and wall terminals. We are constantly expanding the range of outlets in response to market demands. The ECONEXT (W) roof and wall terminals have been especially developed for connection to modern, condensing, high efficiency boilers with a maximum flue gas temperature of 120 ° C (T120).

Various extension kits are available for the vertical terminals to extend the terminal under or above the roof.

For the new wall terminal, the standard straight outlet can be exchanged with a simple rotary lock for a plume deflector or for a Plume Management Kit.
