November 30, 2008 - Vortec introduced its UL listed, Vortex A/C cooling systems for electrical enclosures. Requiring only a compressed air supply to operate, the Vortex A/C quickly installs on electrical control panels to maintain enclosure temperatures within a range of 80° to 90°F (27° to 32°C). The 5000 BTUH Vortex A/C model features dual vortex tube cooling units, each with its own reliable mechanical thermostat to provide two-stage levels of refrigeration. To conserve energy, the first stage offers 2500 BTUH cooling capacity and, if needed, a second stage activates to double the supply of refrigerated air to the enclosure.
At a fraction of the size and cost of a refrigerant-based air conditioner, the Vortex A/C provides reliable, below-ambient cooling in environments up to 175°F (79°C). The “no-downtime,” maintenance-free units incorporate vortex tube technology to convert filtered compressed air into a low pressure, refrigerated air stream distributed throughout the enclosure. Refrigerated air entering the cabinet provides a light positive purge to seal out contaminants, while hot air is expelled through a relief valve. Even when the Vortex A/C cycles off, a “purge-air port” can be opened to create a slight positive pressure in the cabinet to keep out dust and dirt.
As with other cooling capacity models, the 5000 BTUH unit is suitable for NEMA Type 4 and 4X rated electrical cabinets, and can be mounted on the top or side of the enclosure.
