Raille spark detection products are designed for installation in harsh industrial environments such as dust extraction ducts. They operate reliably in those harsh environments and include continuous circuit monitoring and automatic testing to help ensure long service life.
Detectors, extinguishers and control panels have insurance industry approval from VdS in Germany and Factory Mutual in North America.
BM6 series control panels
Manufactured by T&B Electronic in Germany and with capacity to monitor 2, 4, 16 and 32 detector inputs.
Activates extinguishing and other responses according to adjustable risk thresholds.
Details of detection / extinguishing events are displayed in clear, programmable text and saved in the system’s memory.
Spark and fault reports can be viewed on the panel’s LCD screen or downloaded to a laptop spreadsheet.
Model FSK4 spark detectors
Model FSK4 spark detectors are mounted directly to walls of the extraction duct and react to both infra red and visible light, picking up ignition sources such as sparks, embers and burning dust. The detector lens is fitted almost flush to the inside wall of the duct and so does not interfere with material flow.
Options include ATEX version approved for use in Zone 20 explosive atmospheres. Fibre optic probe to allow remote mounting of the detector for high temperature applications. Compressed air cleaning of the detector lens for applications with heavy build-up of residues in the duct
Model FST6 ember detector
Model FST6 ember detectors react to light further into the infra red spectrum than spark detectors and so is not effected by variations visible light. Ember detectors are less sensitive to small ignition sources than spark detectors and are generally used to monitor open conveyors and drop chutes where variations in daylight cannot be avoided.
Water curtain extinguishing
Water curtain extinguishers prevent the spread of ignition sources through dust extraction ducts and conveyors. The extinguishers generate a dense curtain of water spray across the extraction duct when a spark is detected and are positioned so that the curtain of water will be at full spread and density by the time the ignition source reaches it.
The face of the nozzle is installed almost flush with the inside wall of the extraction duct, so does not interfere with material flow. The spring loaded shutter seals the face of the nozzle when not spraying, to prevent the water path becoming blocked. Available in 1-nozzle and 2-nozzle configurations for standard applications and in combinations for larger capacity extinguishing systems.
Argon gas or water mist extinguishing of fires inside machines and storage areas.
High pressure water pumps
Spark detection systems require a guaranteed supply of high pressure water. Raille manufactures a range of water pump stations, designed for this purpose.
The range starts with a compact and low cost unit to supply a small spark detection system. Our largest pump station can supply 2,000 ltr water per minute, with the pressure constantly between 7 and 9 bar.
All are equipped with automatic test and fault diagnosis features to ensure reliability and long service life.
