Enclosures meet increased safety requirements
Certified enclosures can be used in potentially hazardous locations, per ATEX Directive 94/9/EC.
Anoka, MN – Hoffman announced ATEX-certified Zonex enclosures
ATEX-certified Zonex enclosuresfor use in potentially hazardous locations where allowable protection methods include increased safety per ATEX Directive 94/9/EC. The enclosures are suitable for use in Zone 1 and Zone 2, EEx e, increased safety applications. They also provide the installed components with IP66/NEMA 4X environmental protection.
Hoffman enclosures help prevent igniting gas or dust.
“‘Increased safety’ deals with controlling (limiting) the arc or spark of components installed so as to eliminate the possibility of igniting a gas or dust in the environment, as well as controlling the surface temperature of the enclosure,” says Greg Quick, Hoffman product manager. “Zonex Enclosures that are factory populated with terminal blocks and ATEX Certified have limits on the number of terminal blocks installed. By limiting the number of terminal blocks installed, the amount of heat generated by the wire and installed components is controlled. Controlling the temperature rise maintains the enclosure surface temperature below defined limits, which eliminates spontaneous combustion due to known flashpoints of certain gases and dusts,” Quick says.
The enclosures are made from Type 316 stainless steel , and the silicone gasket offers sealing and temperature performance. Side-mounted, slotted mounting brackets allow one-person mounting and installation. Standard enclosures with either one or three gland plates allow for simple modification and wiring, and a lift-off door provides access to components. Enclosures can be purchased as certified components only, which are standard catalog offerings, or Hoffman can provide certified populated and modified enclosures, configured with ATEX-certified terminal blocks, stopping plugs, and drains combined with customer-specified holes, cutouts, and markings.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
