Danfoss / Danfoss Turbocor® VTCA400 Compressor

The new VTCA400 from Danfoss offers improvements on traditional centrifugal compressor designs that are large in physical size and footprint, which ultimately lead to higher cost and space constraints for the end user. The VTCA400 solves this problem by using a patent-pending hybrid compression design that uses a combination of mixed flow and radial impellers enabling both high-performance and a compact footprint. In this design, the first stage impeller uses a mixed flow impeller with both axial and radial components while the second stage impeller uses a radial design. The hybrid compression design allows for a compressor footprint that is half the physical size and weight of a conventional radial-only design. It also maintains high efficiency levels —a 10% improvement in full load efficiency and 30% improvement in IPLV above ASHRAE 90.1-2019 minimums when considering a three (3) compressor, 1200-Ton system.
