Rittal's enclosures now meet all the requirements of standard EN 60079-0:2009. With their innovative silicone foam gaskets, the stainless steel enclosures can be used in Zone 1 (gas, vapours, and steam) and Zone 21 (dust) hazardous areas. The new enclosure designs in IP 66 are ATEX and IEC-certified. In terms of temperature range, Rittal goes a significant way beyond the basic requirements of -20° C to +40°C. The explosion-protected enclosures are approved for use at temperatures ranging from -30 to +80 °C and they have the highest temperature class - T6. Further advantages of the new seals are the improved long-term protection they provide from the ingress of water and other sources of damage.
