Unimog U 427 with Kahlbacher body.
In airport service work, the Runway Light De-Icer (RLD) handles the de-icing of countersunk runway lights. And in doing so, it is especially economical. Its precise spraying technology minimises the consumption of de-icing fluid.
Sensors control the automatic spraying process.
The targeted and compressed expulsion of the de-icing agent can prevent the formation of dangerous rings of ice around countersunk runway lights and thus reduce the risk of damage to aircraft.
At the same time, users of the RLD minimise their consumption of de-icing agent as a result of the precise spraying technology which it features. Upon activating the device, a height-adjustable sensor bar at the front of the vehicle automatically positions itself in relation to the surface which is to be de-iced. During driving, countersunk runway lights are detected by means of a purpose-designed sensor bar and the signal is transmitted to the spraying system at the rear of the vehicle.
Depending on the driven speed, the de-icing agent is expelled via a 1.5-metre-wide jet spray in a targeted manner in the area of the countersunk runway lights. An audible monitoring tone informs the Unimog driver when lights have been detected and when spraying is in progress. If required, the spray button can be actuated manually to initiate an additional spraying cycle.
