This project incorporated the replacement of three existing Liebert precision cooling units in Kalamazoo County’s data server facility. The two new, 8.5-ton Liebert units were installed to maintain a strict temperature and humidity set point in the growing data center. Kalamazoo Mechanical worked with county employees to make sure the construction process would not compromise the valuable server equipment. The climate needed to stay within a tight tolerance. Precautions included tarping systems, portable cooling systems, and exhaust fans. This was a challenging project because the new ceiling units were much larger than the existing units, and much care had to be taken while maneuvering the new units into position.
