Enclosures for hazardous locations
Pentair's Hoffman brand Zonex, IECEX- and ATEX-Certified Enclosures are designed for applications where increased safety is needed to safely house electrical components in hazardous areas.
Pentair Technical Products' line of Hoffman brand Zonex IECEX- and ATEX-Certified Enclosures has been released. Zonex hinge-cover and screw-cover enclosures are designed for use in applications where “increased safety” protection (Ex e), as defined by the ATEX Directive 94/9/EC, is acceptable to safely house electrical components in Zone 1 and Zone 2 rated areas. These enclosures are not intended for use in explosion-proof or flame-proof (Ex d) applications.
The expansion of the Type 316 stainless steel ZONEX platform includes new inch-based offerings in an extended range of sizes, including hinge and screw cover versions. All Zonex models are now offered with enhanced customization options including: material changes, size changes, paint options, holes and cutouts, population of any ATEX-certified terminal block, stopping plug or drain, mounting bracket changes and other modifications. Hinge cover models are ATEX, IECEX, and AEx certified. Screw cover models are ATEX and IECEX certified.
New inch-dimensioned hinge cover enclosures are available in sixteen standard sizes from 12 x 12 x 6-in. to 36 x 24 x 8-in. and come standard with NEMA-style mounting feet on the top and bottom, a full size bottom gland plate and a one-piece continuous gasket on the door and gland plate. Hinge cover models feature a 10-mm brass internal/external bonding provision, a quarter-turn latch with a 3-mm double bit insert and the required panel and bonding hardware. Side mount brackets, a high-temperature silicon gasket, gland plate changes from zero to four and enclosure dimension changes up to 60 x 36 x 18-in. are available upon request.
Screw cover enclosures are available in five sizes ranging from 4 x 4 x 3-in. to 10 x 10 x 5-in. These enclosures feature welded-on, full-width top and bottom wall-mount brackets, a 6-mm internal/external brass bonding provision, stainless steel cover screws, a one-piece continuous gasket and required panel and bonding hardware. A high-temperature silicon gasket is available upon request.
“The Zonex enclosure family now features European ATEX and global IECEX certifications on all products, as well as American AEXe certification on the hinge cover products,” said Greg Quick, Hoffman product manager. “We have expanded the Zonex Enclosures line to include small screw covers and inch dimensions, as well as expanded and enhanced modification and population capabilities, to better meet the needs of the marketplace for enhanced capabilities with short lead-times and the required certification.”

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
