Spark Detection & Extinguishing System ALF 8000

Extensive research and development results in a new generation high-efficient spark extinguishment system. To develop such new system EWS used the wide experience and know-how of its employees with several decades of experience. Also other existing systems have been analyzed. Various systems of other suppliers have been tested extensively.
We had two goals: 1. Analysis of disadvantages of all existing systems. 2. Development of new, beneficial technical solutions. The result is a new generation of Spark Extinguishing System. For example, we noted the high cost of the installation work. New concepts reduce the cost for wiring up to 50%. After we have interviewed many users of Spark Extinguishing Systems we learned the operation of highly integrated control cabinets are often difficult and leads to extensive training and instruction. As a result we decided to design selective operator blocks for each zone whereby the handling becomes very user friendly. Another point of criticism of system users was that the water for extinguishment can disturb the production process – especially if the system triggers an alarm several times each day.  This is often the case. EWS tested the effectiveness of extinguishment in a wind tunnel with air velocity of up to 36m/s [7,000ft/min.]. As a result EWS developed a novel nozzle which allows significant reduced use of water with the same effectiveness of extinguishment as conventional nozzles. Another weak point was noticed – the incomplete auto-supervision. New self-testing devices monitor failures of all important functions of detection and extinguishment. After introducing the EWS Spark Extinguishing System to users they confirm: This really is a new generation of Spark Extinguishing system.
