Performance

The Spark Cooler is ideally suited to mitigate sparks generated in metal and other low-load material processing applications, under non-explosive conditions. Since 2008, the Spark Cooler has been installed in over 500 applications, with fewer than five known fire events occurring subsequent to installation. The Spark Cooler is not an extinguishment system and should never be relied upon to achieve spark eradication in processes where suppression requirements are absolute. The Spark Cooler does not guarantee complete elimination of sparks, and does not preclude the possibility of fire and explosion. Therefore, system redundancy and complementary measures should be taken in conjunction with the Spark Cooler to further reduce the risk of fire and explosion from sparks in applications in which there is potential for catastrophic combustion.

As an ignition-source mitigation device, the Spark Cooler is unique in its performance offering. In metal-related processes, with nonagglomerating materials, the Spark Cooler offers effective spark mitigation (as evidenced by the figures above), minimal pressure drop (less than 1”), zero footprint or space requirement on the shop floor, simple installation (no controls or calibration required), vertical or horizontal positioning, zero maintenance and breakdown (no moving parts), and continuous operation (which results in no system downtime and no energy use).

How It Works

The presence of sparks is a significant problem in the filtration of combustible particles. A spark gets buoyancy from a surrounding bubble of hot air and often moves along, uninterrupted, at the same velocity as the gas stream until the spark hits the filter media. When the spark is deposited on the filter media surface, it can ignite a fire and the filtration system can be compromised. Therefore, designing an exhaust/filtration system that minimizes the risk of spark ignition is critical. Damage dust collector fires

The Spark Cooler is a simple and effective product for inclusion on process systems that works to reduce the frequency of sparks reaching the filter media. Properly applied, it can create turbulence in the gas stream sufficient enough to disturb the thermal bubble surrounding the spark, and thereby allow the lower temperatures of the gas stream to work to reduce the spark’s temperature. In many instances the spark is eventually extinguished. This temperature reduction can reduce the frequency and severity of spark-related damage to dust collection and exhaust systems, including filters, ducting, and collection equipment.
