At Colo4, your equipment and data are protected in an ideal environment with truly redundant HVAC. Temperature, humidity and airflow are continuously maintained and monitored. Cooling is supplied by 30 industry-leading Liebert 22-30 ton downflow units. Unlike many data centers that use one or two chilled water plants to supply cooling to each unit, Colo4 uses an individual roof mounted condenser for each CRAC unit. Our comprehensive approach to cooling far exceeds the reliability of most systems and is only possible in a single-story building.
