Chillers & Central Cooling Plant installations at Hamad International Airport (DOH)

The chilled-water plant is the heart of every Gulf terminal and the single biggest lever on its energy bill. This sub-category covers water- and air-cooled centrifugal, helical-rotary (screw), scroll and oil-free magnetic-bearing chillers, plus the BMS/controls (e.g. Metasys, Tracer SC+) that sequence and optimise them. The defining requirement is high-ambient performance: machines that hold rated capacity and efficiency against 48–52 °C apron air, where standard 35 °C-rated chillers de-rate sharply. Buyers compare IPLV / kW-per-ton, magnetic-bearing vs conventional drivelines, low-GWP refrigerant transition (R-1234ze / R-513A), and AHRI certification. Specifiers also weigh plant resilience, N+1 redundancy and the option to buy chilled water from a district utility instead.

Hamad International is what happens when a state airline designs its own cathedral. Opened in 2014 and already expanded twice, it serves as Qatar Airways' global spine and routinely tops Skytrax's best-airport rankings. 2024 traffic hit 52.7 million passengers and cargo cleared 2.6 million tonnes — both records. Phase C, now in tender, will lift capacity beyond 70 mppa and add a second passenger processing hall.
