Requiring only a compressed air supply to operate, Vortex A/C installs on electrical control panels to maintain enclosure temperatures within a range of 80 to 90°F (27 to 32°C). The 5,000 BTU/hr model has dual vortex-tube cooling units, each with its own mechanical thermostat to provide two levels of refrigeration. To conserve energy, the first stage offers 2,500 BTU/hr cooling capacity; if needed, the second stage activates to double the supply of refrigerated air to the enclosure.
