non spring return damper actuators

How Non-Spring Return Damper Actuators Work?

Without a recurring spring action, this type of actuator offers more precise, continuous damper modulation for a more fine-tuned climate control. They also provide reliable performance for high torque applications and controlled environments. Since there’s no constant clash against the spring mechanism, the actuators can offer benefits, including:

• Reduced power consumption for energy efficiency 
• Lesser maintenance for longer service life
• Cost-effectiveness for suitable applications

Applications Where NSR Damper Actuators Are Critical

Compared to spring-return actuators, non-spring models hold their last position when power is lost. That’s why they are suitable for applications where the damper's position is not required to default to a safe state during a power outage.

Many HVAC systems use non-spring return actuators, including: 

• Air volume control: Air handling units, variable air volume (VAV) boxes and zone dampers
• Smoke extraction: Specific smoke control applications and fire ventilation systems
• Modern building automation: Commercial, industrial and advanced residential settings
