We have many years of experience with VAV and DCV and know how critical it is with regulation reliability and accuracy. The damper motors must respond to everything from varying temperature, carbon dioxide levels, presence but also be optimised in case of pressure drops in the system. Hence they regulate very often. Our damper motor has an infinite life span as it is based on stepper motor technology and not a DC motor with carbon that wears down. It also solves a good regulatory accuracy with very good resolution.
