Water-Cooled Chiller Type and Size Selector
Match your load and duty to a compressor platform. Bands per industry consensus (scroll ≤200T · screw 100–500T · centrifugal ≥300T).
Guidance tool only. Final selection depends on chilled-water temperature, condenser-water design, redundancy (N+1) and site power. Koven Air engineers verify the load calculation before quoting.
