R. STAHL has developed a new cost-efficient design, series 8150 for “increased safety”-protected sheet steel enclosures for a wide range of applications. The enclosure layout has been optimized, thus creating a balance between cost and function for Zones 1 and 2. As of now, the enclosures are available with a complete ATEX and IEC certification for hazardous areas. UL and CSA approvals will follow by the end of the year, thereby providing worldwide certification. The enclosures, including all built-in components, are certified ex works. All suitable terminal equipment has been thoroughly specified in order to provide maximum safety. In order to test compliance with Ex e requirements, R. STAHL carries out in-house computer calculations and tests in climate chambers, which simulate long-term use in extreme environments. The enclosures not only fulfill all requirements concerning shock resistance, maintenance of IP protection etc.; their mechanical layout and equipment configuration have been designed to ensure practical functionality.
The door, which is equipped with robust hinges, has a 130° opening angle and can be fitted with an optional camlock, thus ensuring fast and easy access. The sealing strip below the lid is protected by a drainage edge which drains water below the seal. Thus, the sealing material is never in contact with standing water even during constant spray exposure. In addition to continuously welded edges, the enclosures also feature welded hinges, which rules out weak spots caused by screws. Cost-efficient models in a wide range of standard sizes are available direct from stock. If required, the enclosures can also be manufactured with customer-specific measurements.
