SCHUCH Explosion ProtectedLight FittingsOver more than a century SCHUCH has been considered a specialist for solving problems with particular reference tothe environmental conditions. This point particularly relates to explosion-protected light fittings.The results coming from the SCHUCH's own research and development work serve for continuously providing themarket with new impulses. For instance SCHUCH has significantly influenced the development of the explosion-prooflight fittings for fluorescent tubes which are on the market nowadays as well as of the relevant standards.Impressive Innovation Force1910 The first mine-gas-protected light fittings illuminate the coal mines in the Saarland and in the Ruhrgebiet.1929 SCHUCH disposes of quite a considerable program of explosion-proof and mine gas explosion proof luminaires.The range of production of explosion-protected light fittings is a major sector within the whole manufacturingline.1952/53 Launching the material „glass fibre reinforced polyester“ in the sector of the explosion-protected luminaires.1953 First approval of an explosion-protected light fitting for single-pin fluorescent tubes.1985 After quite a substantial development work SCHUCH makes an application to the Physikalisch-TechnischeBundesanstalt (PTB) in Braunschweig for testing an electronic control gear with regard to its explosion protectionacc. to EN 50014 and EN 50017.1986 Successful certification by PTB. SCHUCH disposes of the first explosion-proof light fitting for fluorescenttubes with electronic control gear.1988 SCHUCH got the world-wide first certification of an explosion-proof electronic control gear for 2-pin fluorescentlamps.1988 SCHUCH launches the world-wide first explosion-protected lampholder for 2-pin fluorescent lamps in „increasedsafety“ protection.1989 World innovation: First explosion-protected light fitting with ECG for standard 2-pin fluorescent tubes. Apioneering solution since from now on standard fluorescent tubes available everywhere could be used in explosion-prooflight fittings, too.Thus, SCHUCH became the forerunner of modern explosion-protected light fittings for fluorescent tubes.1998 Worldwide first explosion-proof light fitting for fluorescent tubes with ECG with „end-of-life“ cut-off system.2002 Worldwide first explosion-proof light fitting for fluorescent tubes with ECG for ambient temperatures of +60°C.2003 Radio interference suppression up to 300mHz2005 Conformance to requirements of the overvoltage catagory III. First certification of an explosion-proof emergencylight fitting with microprocessor controlled intelligent emergency light electronic system, integratedECG, „end-of-life“ cut-off system and for an ambient temperature of +55°C max. By now,millions of SCHUCH explosion-proof light fittings for fluorescent tubes with ECG are in usewordwide, last but not least thanks to the reliable SCHUCH ECG with a life of up to100,000 hours.2010 First explosion-protected light fitting for fluorescent tubes of Zone 2 and Zone 22 for applicationof the energy saving T5 lamp technology.2012 Certification of the first LED explosion-protected floodlight, of emergency fittings and ofZone 2/22 compact luminaires.Worldwide one of the most substantial manufacturing programsOn the whole area of explosion-protected light fittings SCHUCH again and again sets a mark for innovationlike it is shown with the ex-proof light fittings for induction-type lamps.Worldwide SCHUCH disposes of one ofthe most versatile programs in the illumination technics for the gas as well as for the dust explosion protection.
