UV500 ATEX
The UV500 ATEX has a IP 65 stainless steel enclosure with an air purge system Ex pxb to work on hazardous areas classified Zone 1 where a risk of explosive atmosphere is present like refineries or chemical plants. Two alarm contacts are provided if the pressure inside the enclosure drops below the adjustable setting points. This alarm can be used to switch off the power of the enclosure. The analyser is designed to work up to 60°C of ambient temperature to avoid the use of vortex cooler.
