for use in hazardous areas Series R 50 deH, R 100 deH, 100 deH The high performance explosion-proof types R 50 deH, R 100 deH and 100 deH r ­ epresent, within their temperature classification, the most powerful sightglass light fittings presently available in Europe. Using these light fittings, new levels of ­ xtremely e brilliant process illumination may be achieved. Efficient manufacturing techniques coupled with extensive component stocks, result in an interesting pricevalue ratio and short delivery times. Application: High performance sightglass light fitting type R 100 deHSch, 100 W, Ex d e IIC T3 Gb, Ex t IIIC T195°C Db IP67, Ex II 2 G + D, on a basket centrifuge In hazardous areas for the illumination of large vessels, tanks, columns, silos, reactors or closed containers with light absorbing linings or contents, for TV-monitoring applications or any situation where high lighting levels are required. ATEX equipment protection level (EPL): Gb (zones 1 and 2) and Db (zones 21 and 22). Operating The light fittings are completely independent of the vessel interconditions: nal pressure or vacuum. They are also admitted for use in food food processing applications.
