District Cooling & Energy Transfer

Across the Gulf, many airport campuses no longer run their own chiller plant — they buy chilled water by the ton-hour from a district cooling utility. This sub-category covers the utility supply itself and the building-side interface hardware: energy transfer stations (ETS), plate-heat-exchanger skids that hydraulically separate the district network from the terminal loop, BTU/energy meters, and pumping skids. District cooling shifts CAPEX off the airport's balance sheet, removes plant maintenance and central refrigerant risk, and concentrates efficiency at utility scale. Buyers evaluate connected-load contracts, approach-temperature and delta-T performance, metering accuracy for cost recovery, and the resilience of a single bulk supply versus an owned N+1 plant.
