The EGLI retracting cable reels for electrostatic earthing are the first that have been approved for the Ex-zone II, Categories 3G and 3D. EGLI cable reels have a potential free contact which makes possible advanced automated solutions in combination with process control or monitoring systems. As a novelty, a 24 volt version is available, ideally suited for the automotive industry.

Safety hazards are, amongst others, loading and unloading of silo- and tank-lorries, transfilling of chemical products and powdery substances, as well as various tasks in industrial facilities. Egli, Fischer has developed a retracting cable reel for these applications in the Ex zone II, that eliminates the risk of electrostatic discharge, meeting the requirements of all regulations and ATEX 94/9 approved already in 2005. In addition to category 3G – important for the chemical industry – the EGLI cable reels are approved for category 3D as well, i.e. for environments, where an explosive dust atmosphere can develop, as in bulk handling and in silo facilities.

The cable reel with automatic monitoring and an optical function display indicates at all times whether the earthing system is fulfilling its function correctly – therefore the monthly service check expenses can be saved. The monitoring unit is now available in versions for 24 V DC, 120 V AC or 230 V AC.
