August 2017. Detection of toxic gases, bidirectional ultrasonic anemometers and opacimeters.
The Bogotá-Villavicencio route, with dual carriageway, is 28,9 Kms. in length. This beneficial infrastructure includes ten bridges and four tunnels. One of them, located between Guayabetal and Puente Quetame, is the fourth longest in Latin America with a length of 4,4 Kms. The tunnel is built to the highest quality standards and technology, with, for example, an Automatic Incident Detection system and an underground evacuation gallery.
For the gas carbon monoxide gas detection systems of these tunnels, SONDELTOX detectors have been selected, manufactured by DURÁN ELECTRÓNICA. Air quality control is carried out with anemometers and opacimeters distributed by DURÁN ELECTRÓNICA.
