An oil-free compressor with a 400-ton/1,400-kW nominal capacity rating received the Product of the Year Award at the 2022 AHR Expo in Las Vegas. The variable-speed, magnetic-bearing centrifugal compressor utilizes a hybrid compression design that is optimized for use with low-GWP refrigerant R-1233zd.

The Danfoss Turbocor VTCA400, which is suited for water-cooled chiller applications, also was named the winner in the Cooling category. The chiller design uses a combination of mixed flow and radial impellers. As a result, the VTCA400 reduces footprint and weight by up to 50 percent compared to traditional designs, which the company says gives users the advantage of a more compact chiller design and more mechanical room space. Other benefits include the ability to incorporate multiple compressors in a single chiller for built-in redundancy and improved part load performance. 

A panel of third-party ASHRAE member judges selected the winning product from this year’s 10 AHR Expo Innovation Award winners. Danfoss has now been recognized more than 30 times over the 18-year history of the Innovation Awards program.
