Restricted-breathing LED high bay for Zone 2 gas and Zone 21/22 dust areas, in two sizes from 20 W to 200 W.
EXP-HB is an LED high bay for hazardous locations. Its gas protection is restricted breathing, Ex nR IIC Gc, which suits Zone 2, and its dust protection by enclosure, Ex tb IIIC Db, suits Zones 21 and 22. The die-cast ADC12 aluminium body carries a tempered-glass cover and seals to IP66.
Two enclosure sizes cover 20 W to 200 W: HB1 from 20 W to 80 W and HB2 from 100 W to 200 W. The temperature class depends on wattage and site ambient, from T6 / T80 °C up to T4 / T130 °C for HB2 at 200 W and +60 °C, as tabled in certificate IECEx TPS 24.0067X. Four optics (30°, 60°, 90°, 120°) and six colour temperatures from 2700 K to 6500 K are offered.
