­ 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.
