All the units that have been installed use the new 9NAD model. This involves a high-efficiency, lightweight and compact design, specifically designed for 12-meter vehicles intended to operate in the climates of central Europe. It incorporates a cooling circuit in aluminum, motors without brushes in the fans and turbines and a recycling system that allows the entry of all outside air and the extraction of air from the interior of the bus.
Its mechanical fixing system makes its installation cleaner, easier and more economical.
It also makes it easier to maintain thanks to the accessibility of the system components and the incorporation of the frameless air intake filter.
The 9NAD model is adaptable to different configurations, from diesel vehicles to hybrid vehicles and also 100% electric vehicles.
