Chilled water is used to cool and dehumidify air in mid- to large-size commercial, industrial, and institutional facilities. Water chillers can be water-cooled, air-cooled, or evaporatively cooled. Water-cooled systems can provide efficiency and environmental impact advantages over air-cooled systems.

Regular Maintenance Keeps Chiller Efficiency High. To help today’s high efficiency chillers maintain those efficiencies in the field, their major components — tubes, oil, compressor, condenser, refrigerant, and starting equipment, to name a few — need to be inspected and maintained regularly.

Industrial Chiller Maintenance Checklist. Inspection of all water inlets and outlets for leaks should be done routinely. All components of the compressor unit should be inspected including checks for oil levels, leaks, vibrations, operating temperatures variations. Electrical contacts should be inspected and cleaned.
