Does IBM use CFC refrigerants?
IBM does not install new chillers that use chlorofluorocarbons (CFCs, e.g. CFC-11, CFC-12, etc) as refrigerants, but it does use CFC refrigerants in its existing building chillers and cooling systems. However, as new and less ozone depleting refrigerants become available, and where feasible, IBM locations are phasing out of CFC-based chillers. Chillers are close-loop systems. If maintained properly, only a small percent of a chillers charge would leak under normal operating conditions. IBM locations are required to maintain their chillers in good condition and preventive maintenance must be conducted.
