Model O

Bullerjan O – the international model


The Bullerjan of the series O is nearly similar to the Free Flow model.

This is the first choice for the European market, except of Germany, Belgium, Austria and Switzerland, because we have to meet special requirements in these countries.
Highly effective, realiable, safe and durable. Different performance classes (8 – 13,5 kW) enable it to be used in small, but also in verly large rooms.
