⚠️ Centrifugal Impeller Aerodynamic Surge Line (Low Flow / High Head Lift PSI)

Centrifugal Chiller Surge Line Calculator

Model aerodynamic impeller blade stall and catastrophic reverse flow surging in centrifugal refrigeration compressors: calculate the compressor surge boundary line based on compression lift ratio versus inlet guide vane (IGV) refrigerant volumetric flow, size modulating Hot Gas Bypass (HGBP) valves, and chiller commissioning profits.
