Boiler for olive pits 

At DOMUSA TEKNIK we have achieved a technologically advanced product that, in the certification process, has obtained the highest possible qualification in Europe (Class 5 according to standard EN303-5) in terms of performance, safety and low gas and dust emissions to the atmosphere.

Advantages Bioclass TR + DR


The BioClass TR+DR boiler manages to considerably reduce fuel consumption on lowering the temperature of the combustion gases, achieving performances of up to 95%.

The Bioclass TR+DR incorporates electronic modulation that adjusts the power of each boiler to the needs of the installations, preventing fuel waste. This boiler comes the reserve tank included .


The cleaning of this boiler is totally automatic. It has a set of turbulators which, apart from retaining the passage of fumes, in order to improve performance, are responsible for cleaning remains of ash in the fumes outlet.

These turbulators are attached to a motor shaft by means of a systems of cams that periodically cause a vertical movement, thus cleaning the fume outlets.

The burner has an automatic ash cleaning system. The lower part of the burner combustion has a cleaning system that is periodically responsible for sending the ash generated in the combustion, to the ash pan. The cleaning is also carried out with the burner operating, meaning it does not affect the comfort of the installation, thus reducing the boiler consumption.


The BioClass TR + DR 10, 16, 25 boilers have an innovative return preheating system. The HotStream system avoids complicated mix systems to avoid condensations that might occur due to the effect of cold returns of the installation.

This pre-heating system admits direct returns to the boiler of up to 25º, which permits making direct installations, with any type of hydraulic configuration of the installation.


This boiler is supplied in one single package, including the reserve tanks, thus facilitating transport.
