ATEX is a European directive that stipulates standards for equipment used in areas where explosive gases, vapor-air mixtures or combustible dust can occur. It defines how to safely operate equipment in these environments and requires that electrical enclosures meet a specific standard. Unlike the Ingress Protection (IP) ratings of North America, UL HazLoc and ATEX evaluations consider different factors to rate the integrity of electrical enclosures.

This is why it is important to understand the differences between the two ratings. The ATEX classification does not only consider the mechanical risks of the device but also electrical safety, thermal resistance and temperature ratings. The ATEX designation will include a suffix that shows the Type of Protection, Equipment Group, Gas Group and Temperature Class. A further suffix indicates if the device is suitable for Gas or Dust applications.

The EL30 explosion proof actuator is designed for a wide range of applications and features advanced roller screw technology that provides up to 15 times longer travel life than ball screw solutions, as well as increased load capacity. The actuator is rated for UL HazLoc, ATEX and IECEx compliance for use in hazardous locations. It includes two auxiliary dry contact limit switches to confirm valve position and can be fitted with a thermostatically controlled anti-condensation heater.
