EC-Flow Technology™

EC-Flow is a proprietary algorithm developed by US Draft Co in an effort to improve upon the current PID technology used for controlling vent pressures. EC-Flow utilizes predictive algorithms to achieve set-point faster during transient operation, and maintain smooth operation during steady state operation. EC-Flow is designed to operate electronically commutated motors, VFD’s and damper actuators.
