Designed for maximum indoor cooling at the most efficient operating cost for year-round operation in the demanding equipment shelter environment. The DUAL-TEC operates on both AC and -48VDC positive ground power under normal power supply conditions. If there is a loss of AC power supply, the DUAL-TEC will continue to operate as a free-cooling or ventilation system using the shelter’s DC power. These units supply 100% of rated cooling airflow in free cooling mode with ability to exhaust the same amount through the unit itself without any additional relief openings in the shelter.
Designed to mount in place of existing 3 Ton Supply/Return Footprint units.
