Catalytic de-oxidation: 100 % chemical-free, environmentally friendly, and reliable corrosion protection with longer service life of district heating systems.

Reliable corrosion protection and longer service life of district heating systems 

An innovative technology, catalytic de-oxidation (DeOx), removes all oxygen in the district heating water and protects piping against corrosion.

The transmission company VEKS, supplying 20 local district heating utilities, had in 2013 high expectations when they put the newly acquired catalytic de-oxidation plant from BWT into operation.  The DeOx plant at VEKS was the first of its kind on a large scale, and the transmission company advocates that catalytic de-oxidation is a future-proof, environmentally friendly and even inexpensive method for removing oxygen from district heating water.

Top quality water ensures longer service life
There are currently three 150 m3/hour catalytic de-oxidation systems in the Copenhagen district heating area.  With the BWT DeOx plants, VEKS has managed to reduce operating costs by more than half – and with a payback period of only five years.

BWT has installed serveral DeOx plants into Danish district heating systems. The plants protect against corrosion and contribute to a long service-life of the piping.

A DeOx plant is installed directly into the loop of the district heating piping and when needed, it automatically removes oxygen from the district heating water. A DeOx plant is dimensioned according to the customers’ needs.
