During drilling operations in tunnels, the presence of dust causes serious problems to operators' health and significant reductions of
productivity.

Thanks to Tecnorer’s advance technology of dust reduction system, it is possible to monitor constantly the quantity of dust in the air (in option) and it allows a complete elimination of dust residue that hinder the drilling operations.

The creation of a "mobile wall filter" ensures excellent results in terms of economical use, dust reduction and adaptability to the perforated material.

In addition for being expensive in terms of the number of workers needed, the traditional dust reduction systems usually cause also a
significant waste of water, making the construction site less livable and reduce, drastically, the visibility during the operations.

Tecnoter has designed an advanced system that able to spray water directly on the demolition point when dust residue is created.

Using in “smart spray” mode, this innovative system allows a total reduction of residue assuring the use of small amount of water (usually less than 300 litres per day), plus complete visibility, and a significant reduction of costs. It also keeps construction sites clean.

Tecnoter's dust reduction equipment, installed on a mobile crushing system, assures a total elimination of dust residues, preserving the productivity of the operations and air quality.

In addition, Tecnoter's advanced technology constantly monitors the work place (optional) with a controlled spraying action in the points where dust arises using a low amount of water.

The use of an external tank of only 500 litres and the adoption of "smart spray" operating mode associated with the environmental monitoring system (optional), allows the crushers to operate independently for several days.

The integration of a suitable dust reduction system on a fixed crushing site has always been a big challenge. In comparison to the old drip systems and mist cannons, the dust reduction system, based on a controlled spraying of water (even from an open air basin),  allows the elimination of dust while maintaining the humidity of the treated part.

Tecnoter’s dust suppression systems for fixed workstations can be integrated with environmental monitoring modules (optional) in order to allow the activation and automatic adjustment of each single atomization point.

The water consumption for each station ranges from 0.2 litres to about 4 litres per minute, depending on the external conditions and on the type of the crushed material.
