200 to 3000 Nominal Tons (703 to 10551 kW)

Carrier’s AquaEdge® centrifugal

chillers offer:
• The use of non-ozone depleting
refrigerant HFC-134a
• An annual leak rate of 0.1%, one of
the lowest published in the industry
• The ability to store the entire charge
of refrigerant inside the chiller,
minimizing the chance of leaks
during refrigerant transfer for
