Fixed Automated Spray Technology increases road, runway, and taxiway safety. This in turn decreases the costs for interventions, and the environment benefits from reduced salting.
Using the microFAST technology developed by Boschung and patented worldwide, the anti-icing agent is applied to pavement surfaces in a fine, invisible and dense stream.
The spraying period and the volume of anti-icing agent is individually configured and automatically controlled by the FAST system, where preventative spraying can be utilized to avoid ice buildup.
microFAST technology is reliable and requires minimal maintenance. With a maximum installed depth of 40 mm, the system can be easily installed and operated at any location, including on runways and taxiways, grooved or not.
During spraying, the stream of anti-icing agent is atomized and, as a result, is invisible to users. Landing and departing aircraft immediately distribute the anti-icing agent over the runway surface.
The spraying period can be adjusted from 30 seconds to 3 minutes, where 30 seconds is equivalent to approximately 2 g/m² of salt.
A protective layer of anti-icing liquid is applied in a very short time (all done in about 50 seconds)

The patented microFAST high-pressure fine spraying system consists of a 100 meter long strip with built-in nozzle bodies which, as a general rule, are installed at 5-meter intervals. The anti-icing agent is evenly distributed onto the road surface in the form of an invisible spray mist.
Check valves are incorporated into the nozzle bodies in order to prevent the ingestion of dirt. As a result, the system is virtually maintenance-free.
In the event of an ice hazard, the spraying process can be activated automatically using the FAST system. The spraying period can be adjusted as required (from 30 seconds to 3 minutes), thus ensuring that the optimum amount of anti-icing agent is applied. As part of a regular de-icing program, or in the event of unplanned operations requiring multiple sprays, the system can be perfectly adapted to suit the existing conditions.
In addition to the pump, the pump station incorporates a control unit and a storage tank for the anti-icing agent.
The microFAST control unit can be fitted with ease in any runway.
