Description
EMHB 1 Ex luminaire is designed to illuminate, among others:
- industrial halls and spaces classified as zones 1, 2, 21 and 22 of the explosion hazard of dust, gases,
- vapors and mists of flammable liquids,
- auxiliary rooms with high dustiness with the possibility of splashes of water, i.e. boiler rooms, hydro junctions, baths, garages, shelters, warehouses in open and closed areas,
- workstation process lines, among others: chemical, petroleum, petrochemical, gas and wood
industries, processing of loose mine, construction and food materials, - places with increased temperature.

[1] According to the table of execution types – point. 3.1; Rated power with a tolerance of ± 5%
** At 230VAC and 160W luminaire power;
*** When using a cable gland with a lower IP or a narrower operating temperature range, the parameters of the entire luminaire are reduced – see point 8.2 in instruction manual
Design and operation
- body – aluminum alloy,
- back cover – aluminum alloy,
- pressure ring – aluminum alloy,
- toughened glass,
- LED light module,
- as standard, the luminaire has two Ø20mm holes with a M20x1.5 cable gland and with an M20 stopping plug. Other configurations others on request,
- pass-through clamps enabling the use of wires from 1mm2 up to 4mm2,
- mounting eyelet,
- luminous flux adjustment via 1-10V or DALI interface according to versions.
Advantages
- solid, compact structure,
- simple, easy and quick assembly,
- high resistance to industrial corrosive environment, very high luminous efficiency,
- high-quality power supply and LED diodes,
- very high tightness IP66 / 67,
- resistant to UV radiation.
