The GreCon DLD 1/9 spark detector contains the patented optical detector system and IDT® for: Detection of sparks, glowing embers and hot, non-smouldering particles The U.S. Patent and Trademark Office grants Fagus-GreCon the patent for a novel optical detector that identifies dangerous ignition sources (U.S. Patent No. US11199441B2). Fagus-GreCon, the leading provider of fire prevention systems, thereby reinforces its role as a technological leader in fire prevention. The company’s innovative optical detector is a key prerequisite for further strengthening the interconnection of fire prevention, production reliability and quality assurance. A powerful trio Thanks to Fagus-GreCon’s recently patented optical detector system, spark detectors are becoming even more reliable, as they can now be customised to the requirements at the installation site with more precision than ever before. This is made possible by multi-sensor technology which has been integrated in the optical detector to capture signals from the infrared radiation spectrum. GreCon IDT®, Fagus-GreCon’s intelligent detector technology processes the signals

Preventive fire protection systems integrated into process control perform tasks for ensuring product quality in addition to working as an early warning system today thanks to smart sensors and their smart networking. A contribution to productivity increase and quality assurance The digitalisation growth of the last few months opens up new options for designing many different processes more efficiently in integrated preventive fire protection of industrial production systems as well. Preventive fire protection systems integrated into process control perform tasks for ensuring product quality in addition to working as an early warning system today thanks to smart sensors and their smart networking. Direct data exchange with production control not only permits process visualisations, but also control and regulation processes. This increased connectivity is the most important building block in order to predictively plan maintenance tasks with the help of data analyses in fire protection facilities and to increase the usage duration of components at consistently high plant safety in future as well. Additionally, the risk of unplanned downtimes reduces and productivity increases.

GreCon fire protection concept sees to safe beet chip drying at Nordzucker When drying beet chips, a by-product of the sugar production that is popular as animal feed, fire can easily occur in the dryer drums and the downstream transport ducts. Due to very high drying temperatures of about 600 degrees, glowing particles can occur even in the area of humid chips. If these glowing particles reach the dried material at the dryer outlet, they can result in big glowing embers. If ignition sources reach the downstream transport or exhaust ducts, fire can spread out in large parts of the dry chip processing and destroy, at worst, complete production plants. Although spark detection and temperature monitoring have been standard in these plant areas for many years, an automatic extinguishment has, however, been missing in the entire industry. This insufficient safety equipment has been a very unsatisfactory situation for Europe`s second largest sugar manufacturer, Nordzucker AG, for a long time and led to cases of damage and production interruptions

Spark extinguishing systems have been an integral part of security concepts of preventive fire and explosion protection in the various industrial processes. The task of this technology is to detect the smallest ignition source such as sparks and glowing particles in time and to extinguish them safety by local limited extinguishing measures before these sparks and glowing particles could damage machinery or other equipment. Especially in pneumatic transport ducts is this a thousand fold proven technology to protect filter systems, silos or bins against fires or explosions. Gladly GreCon will show you during the POWTECH how simply it will be possible to protect your plant as well. If a spark will be detected a fine extinguishing efficient water mist spray will be inserted in the corresponding exhaust ducts for an adjustable extinguishing time to safety extinguish the sparks. This will certainly prevent that the spark can be the fire or explosion reason in the filter,

... reliably prevents fire in dryers, filters and silos The occurrence of glowing or hot particles cannot be completely excluded from many processes. If ignition sources are transported into filters and silos via the extraction system or other conveying facilities, devastating fires and explosions can be triggered. By means of infrared sensors and downstream extinguishing nozzles, the ignition sources in mechanical and pneumatic conveying systems are reliably detected and extinguished before they reach plant areas at risk. For those applications in which water extinguishment is not possible or reasonable, GreCon developed special fire traps or diversion gates, which prevent the damaging effects of the ignition sources as quickly as the water extinguishment. Not only has the technical implementation of the principle “extinguish sparks before fire occurs” been permanently improved and optimised until now. A high level has been reached especially regarding the operation of the system and the documentation of alarms and
