Patlite has introduced explosion-safe AR070 and AR-078 LED stacklight towers for Zone 2 and Zone 22 application environments. Each model is rated IP65 without alarm/ fl ashing and IP54 with alarms/fl ashing and features a glass fi ber-reinforced polyester base, a 1.5-meter cable and a sealed cable exit. The towers can be wall or direct-mounted and stacked fi ve high in red, amber, green, blue and clear to suit varied application needs. AR-070 models are 40mm in diameter and have an optional 1/2” NPT, and AR078 models are 60mm in diameter and have an optional 3/4” NPT. Both models offer colour coordinated wiring to correspond with the stacklight colour, which it is claimed simplifi es installation. They also feature interchangeable LED modules that remove the need for rewiring.
