Cabinet air cooler

Protecting electronics from high external temperatures while maintaining sound levels of only 60 dBA at 3 feet, this compact air conditioner features internal muffling and an external sleeve for added insulation. It stands 5.2 in. high for mounting in confined spaces. The mini-Cabinet Cooler incorporates a vortex tube that cools ordinary compressed air to 20°F, providing a constant purge of air to keep the panel free of dust and contaminants. It installs quickly through a standard electrical knock-out and will maintain NEMA 12 integrity of the enclosure. Applications include cooling programmable controllers, CNC panels, camera and laser housings and computer cabinets. EXAIR Corp, Cincinnati, OH. Free info--Circle 760. http://www.OneRS.net/106df-760

Modular Enclosures for Process Control in Manufacturing

Enclosures surrounding equipment for monitoring, measuring and controlling continuous industrial manufacturing processes must be flexible and expandable to adapt to constantly changing requirements. Modular units with flexible features and accessories allow such versatility in dynamic configurations.

The TS8 modular enclosure system uses a patented 16-fold frame that lends torque-resistance while twin columns allow bi-level mounting on the inner and outer levels of the frame. A 25mm hole pattern facilitates depth configuration flexibility for vertical mounting panels, allowing dual panel installation. The continuously-welded dual-tube frame can handle more than 1500 lbs of equipment.

Modular plinths underneath the enclosure allow space for cable management. Removable cable base sections facilitate cable tray installation. Additional accessories, such as cable ties and clamps, are available to manage cables for high-density I/O devices. In earthquake-prone environments, standard models for these plinths provide 330 lbs siesmic Zone 3 protection; enhanced plinths are certified for Zone 4 at 400 lbs. Additional stiffners, corner gussets and diagonal brackets increase Zone 4-certified weight capacity to 1100 lbs.

Clear viewing doors keep I/O visible for troubleshooting and diagnostics. Rated for UL Type 12 and NEMA 1, 12, and 13 protection, these cabinets provide integral continuous electrical bonding and roof-mounted eyebolts for grounding and EMC protection.

Climate control accessories range from air conditioners and heat exchangers to filter fans. These can be mounted at various heights on front and rear doors to provide cross-ventilation; such horizontal cooling techniques avoid short-cycling problems common with roof-mounted cooling devices. Shallow 1.75-in. deep fans maximize usable space within the enclosure.

These versatile enclosures are also used in heavy industry as well as dense server network applications.
