Description
The Belimo CQB24-SR-L is a high-quality 24V non-spring return (NSR) damper actuator engineered for precise modulating control in commercial and industrial HVAC applications. Featuring a normally open (N/O) fail position and a 75-second runtime, this actuator delivers reliable, repeatable damper positioning to support efficient building automation and air distribution systems.
Built to Belimo’s exacting standards, the CQB24-SR-L is designed for straightforward installation and long-term dependability in demanding environments. Its modulating control capability allows for accurate proportional damper positioning, making it an ideal choice for variable air volume (VAV) systems, economizers, and other applications requiring precise airflow management.
