EVNL-B LED ATEX/IECEx – Zones 2/21/22 – Highbay / Projecteur
Cortem Group presents the lighting fixtures and floodlights of the EVNL-B series, suitable for plants in zone 2, 21 and 22, keeping cost reductions at the foreground, improving the quality of the product and increasing the lighting solution specifications. The advantage of the EVNL-B lighting fixtures is the implementation of the “Ex nR” version combined with the “Ex op is” which classifies the equipment as a restricted breathing device with certified optical safety. The careful design, together with the meticulous choice of materials to seal the lighting fixture, limits the entry of flammable gases, vapours or mists during normal operation of the lighting fixture. The particular design of the body in aluminium alloy allows quick and easy dispersion of the heat generated during normal operation of LED lights. Furthermore, the geometric structure of the cooling fins has been designed to minimise the deposits of combustible dust and allow air or water present in the surrounding area to exert a cleaning action on the fixture. The EVNL-B series can be supplied with 10°, 20° and 40° optics (60° and 80° optics are also available for the EVNL-60B series) fitted directly on the LED board, which modify the photometry allowing different concentrations of the light beam. An advantage provided by the LED floodlights of the EVNL-B series is the assurance that lighting will never fail. In fact, if one LED stops working, the others will continue. Furthermore, during the activation stage, the light reaches its maximum power emission immediately.
