E2S Warning Signals has developed a range of LED beacons for use as warning beacons and status indicators for systems installed in hazardous areas and industrial environments. According to the company, the LED units, using a multiple array of high-power white Cree LEDs, offer significant advantages over traditional Xenon strobe technology. The typical light output level from the LED units is a very bright 338 candela, higher than the 120 candela effective intensity of a 5J Xenon tube unit.
SWEP’s new 250AS model is specifically developed for high-efficiency air- or water-cooled reversible chiller applications. Large ports and asymmetric plate design enable an effective operating range of 80-250 kW (23-71 tons).
E2S Warning Signals has added visual signals to its explosion proof and corrosion resistant GNEx family. Suitable for all Zone 1, 2, 21, and 22 hazardous location signaling applications the GNEx beacons have extended temperature range with IECEx and ATEX Ex d approvals. For high-ambient light or long distance signaling the GNExB2 beacon is available in 10, 15. and 21 Joule variants producing up to 902cd.
