Belimo Non-Spring Return Actuators

Extensive torque offering (18 in-lb to 360 in-lb), with direct coupled, linear or rotary actuators that can handle many applications.
All non-spring actuators use brushless DC motor technology, which is controlled by an Application Specific Integrated Circuit (ASIC).
Minimum torque guaranteed over entire specified operating range; no loss in performance due to temperature, supply voltage or speed.
Electronically protected against over-load.
Low power consumption provides higher efficiency and smaller transformer sizing.

Applications

Belimo actuators are designed for use in a wide variety of HVAC damper applications. With our comprehensive torque range and ability to direct mount or mount to a jackshaft, solutions are available for control dampers, air handlers, economizer units, VAV terminal units, fan coil units, fan shutters, and unit ventilators.
