The sanding systems can be supplied for all transportation systems to refill the sand into the sandboxes of the rolling stocks.
They can be provided as a fixed installation or as a mobile unit, in case complete with a sand storage silo or other types of sand filling units.
The fixed solution is essentially composed of a sand storage silo, a propeller, and local sand tanks, each one complete with one or two dispensing guns.
The sanding system is completely automatic and equipped with a compressor and centralized dust filtering unit. Sand transfer piping can be fitted to the roof or inside a trench at floor level.
