Description

The SFDN or SFDNX series of floodlights are suitable for operation in potentially explosive atmospheres in Zones 2 and 22 and in rough ambient conditions with high mechanical load, humidity or dust. The tough enclosure, an impact-resistant protective glass up to IP66 and a large operating temperature range permit use in applications such as oil refineries, chemicals and petrochemicals installations, shipbuilding or other industrial sectors. Typical applications for hazardous dust areas are found wherever flammable dust arises, for example in the cereals or flour industry, mills, sugar production or wood processing industry.

The light is designed with type of protection “Ex nR” and may optionally be implemented with an aluminium or stainless steel enclosure. High pressure discharge lamps with a maximum output of 400W are used as illuminant to provide the appropriate illumination density. For the design with an aluminium enclosure, it is also possible to have a symmetric or asymmetric lamp structure.For the electrical connection, an M20x1.5 cable gland is provided, approved for the explosion protected area.An adjustable swivel bracket makes the light suitable for wall and ceiling mounting at a medium or high suspension height. An adapter for mounting on a pole is similarly available.
