Spark Detection
Infrared spark detection provides a superior level of safety
The Eximio spark detection system features the most advanced detection, controls, and extinguishing technology in the world. By utilizing Infrared sensing elements the detectors an insensitive to daylight and capable of detecting black body particles, glowing embers, sparks, and flames.
Eximio Infrared Spark Detectors are Insensitive to Daylight
Spark detection systems can save industries from costly fires and dust explosions. By combining advanced infrared detectors with intelligent controls the Eximio system offers premium safety solution that minimizes false alarms and keeps you in production.
Spark Detection Basis
The Eximio Spark Detection and Extinguishing System consists of an Infrared Spark Detector that identifies dangerous particles (ignition sources) in process flows.
Once a particle is detected, it is extinguished in milliseconds by full cone water spray nozzles before it can create a fire or a dust explosion.
The detection and extinguishing functionalities are controlled by the Eximio-C Control Unit.
Temperature at Which Combustible Material Ignites
The expression ‘spark detection system’ may be misleading; one could believe that sparks are the only cause of industrial fires and explosions.
A particle will emit light (spark), visible to the human eye when it has a temperature of about 1,300°F or more. All particles below this temperature are perceived by the human eye as ‘black’ particles.
The adjacent chart illustrates the temperature combustible material ignites. According to the National Fire Protection Association, NFPA, combustible material can ignite at much lower temperatures than 1,300°F. ‘Black body particles’ such as a mechanical impact may never emit light but can still generate enough energy to create ignition.
| Material | Cloud °C | Cloud °F | Layer °C | Layer °F | Min. Cloud Ignition Energy mJ |
|---|---|---|---|---|---|
| Wood | 470 | 878 | 260 | 500 | 40 |
| Wheat Flour | 440 | 824 | 440 | 824 | 60 |
| Cellulose | 480 | 896 | 270 | 518 | 80 |
| Sugar | 370 | 698 | 400 | 608 | 30 |
| Cocoa | 510 | 950 | 240 | 464 | 100 |
| Aluminum | 610 | 1130 | 326 | 619 | 10 |
| Coffee | 720 | 1328 | 270 | 518 | 160 |
Intelligent Infrared Detection
Infrared Spark Detectors
Infrared spark detectors are insensitive to daylight minimizing the potential for false detections. The IR technology also allows the detector to see particle temperatures at ranges where traditional ultraviolet detectors cannot. These FM-approved intelligent detectors provide superior detection of sparks and fires.
InfoLED™ technology allows for operators to see detections and detector status in real time either in the process or at the controller.
Features include self cleaning lens, quick access process adaptors, 180° viewing angle, quick connect detector cable, and process shields.
Intelligent Control System
Eximio-C
The most advanced prevention control system in the world offers the ability to monitor multiple gas detection, spark detection, and quick suppression systems with IntuVision™. Its modular design and decentralized system architecture allows it to handle single applications to entire processing facilities.
IntuVision™ is an intelligent operator interface that provides users with a clear, informative information and user friendly menus.
Features include the ability for remote monitoring, networking connections, and interlocking relays.
Water Extinguishing
Full Cone Water Nozzles
A variety of different water nozzles are available to extinguish sparks in any applications. Nozzles for conveying ducts, drop chutes, and open areas are available.
Full cone water spray produces a powerful extinguishing zone to penetrate material flow and cover the entire duct cross section. Each nozzle features a solenoid valve for quicker reaction time and the optimal reliability.
Features include flex connection for quick access, quick release process adaptors, and no moving parts limited any potential wear.
