Willis Carrier invented centrifugal refrigeration in 1922 and today, more than half a century and 25,000 machines later, Carrier hermetic centrifugal liquid chillers still lead the way in comfort air conditioning and process cooling. What’s more, the modern day 19 Series centrifugals are specifically designed to afford significant dollar savings on utility bills, in every way possible. The Carrier 19 Series centrifugal design philosophy has always been to offer a variable line which meets each
