Fixed Automated Spray Technology (FAST) systems are proven to increase safety and improve the flow of traffic in critical areas.
Fixed Automated Spray Technology
Over several decades, the Boschung Fixed Automated Spray Technology (FAST) has proven its worth as stationary winter maintenance equipment. Many years of experience and ongoing development have resulted in a systematic solution which operates safely and ecologically.
The spraying heads are embedded into the pavement surface and the valve units with all the active elements are installed at the side of the pavement.
In cost-benefit analyses, the FAST achieves a very high cost-effectiveness factor.
The FAST installation consists of valve units and patented spray disks in the pavement surface. The spray disks are protected against heavy weights and the abrasion caused by snowplows or aircraft tires. The anti-icing solution is regularly distributed onto the pavement surface using pressure provided by the system's pump. The spray width and spray area can be adapted to suit the prevailing conditions.
The patented valve unit incorporates the solenoid valves, the valve control card, and the accumulator tank. This tank contains sufficient pressurized anti-icing agent for one spraying cycle. In this way, the size of the feed lines is kept to a minimum and they are designed to extend the length of the spraying system to more than 1,000 meters.
In addition to the pump, the pump station incorporates the control unit and the storage tank for the anti-icing solution.
In the event of an ice hazard, the spraying process can be activated automatically with the FAST system. The system can be perfectly adapted to suit the prevailing conditions by using either programmed spray schedules or multiple impromptu spraying operations.
The FAST system is installed invisibly and indestructibly under the pavement surface. The valve units, with all active elements, are fitted at the side of the pavement. Passive elements such as spray disks are installed on the pavement surface, and can be replaced cost-effectively when the surface is renewed.
Throughout many winters, the FAST system has proved itself in stationary winter service. Many years of experience and continuous development have produced a systematic solution which is safe and environmentally friendly.
In cost/use analyses, the FAST system achieves a very high economic viability score.
The FAST system can be easily installed in any runway.
