Detailed description
The FLEXATEX 1027U is an explosion-proof floodlight intended for explosive atmospheres. It covers zones 1 and 21, that is, locations where an explosive gas or dust atmosphere is likely to occur in normal operation, as well as zones 2 and 22, where it only occurs accidentally. Its certification was issued by LCIE Bureau Veritas.
Applications
- Oil sites, refineries and hydrocarbon depots.
- Classified chemical and petrochemical installations.
- Silos, flour mills and powder handling installations, where the risk comes from dust.
- Treatment plants and anaerobic digestion units.
- Exposed outdoor areas, the operating range going down to -40 °C.
Technical highlights
- Covers zones 1-21 and 2-22: the classification determines whether the equipment is admissible. A luminaire designed for zone 2 only cannot be installed in zone 1, whereas the reverse is possible. This model covers both risk families, gas and dust.
- Yellow anodised aluminium body and 316L stainless steel clips: anodising protects the aluminium and 316L resists chlorides. In a refinery or by the sea, it is often the fixings that degrade first on a poorly specified luminaire.
- Surge protection from 6 to 12 kV: large industrial sites are exposed to transient overvoltages, especially on overhead networks. On equipment installed in a classified zone, an electronic failure is not handled like an ordinary breakdown.
- IP66 and IK10: tight against dust and powerful water jets, with the highest level of mechanical resistance in the series.
- Range from -40 °C to +50 °C and CREE LEDs: the range covers unheated outdoor installations as well as process areas where the ambient temperature rises.
- Power from 50 to 200 W, flux from 5,400 to 21,600 lm: from local lighting of a control station to general lighting of a unit.
- Dimensions from 270x220x103 mm to 350x280x104 mm depending on the power.
The choice of a luminaire for an explosive atmosphere is not settled on photometry alone. You must start from the zoning established for the site, check that the equipment classification covers the installation zone, then size the flux within what remains admissible. Any change to the zoning during operation requires this check to be repeated.
