Types of Damper Actuators

The damper actuators produced by our company mainly include the following types:

Non Fail-safe Damper Actuator

Non-Fail-Safe Damper Actuator (also called Non-Spring Return or NSR) is an electric motor for HVAC dampers that stays in its last position when power is lost, requiring continuous power to move but not to hold, making it efficient for normal operation in air handlers.

Spring-return Damper Actuator

Spring-Return Damper Actuator is a fail-safe device that uses an internal spring to automatically move an HVAC damper to a preset safe position (like closed) upon loss of power or control signal, ensuring system safety, often used for outside air dampers to prevent smoke/gas spread or freeze damage.

Standard Damper Actuator 4_6Nm Mondulating
Standard Damper Actuator 2Nm ON/OFF

Fast-running Damper Actuator

Fast-running damper actuator is a high-speed HVAC component that quickly opens and closes air dampers for precise airflow control, crucial in environments like fume hoods, cleanrooms, or labs needing rapid response for safety or room pressure.

Smoke Control Damper Actuator

Smoke Control Damper Actuator is an electromechanical device that automatically opens or closes dampers in HVAC ducts to manage smoke movement during a fire, either by closing to block spread (containment) or opening to exhaust smoke and pressurize safe areas (exhaust/pressurization), ensuring occupant safety by preventing smoke inhalation.

 

Advantages of Damper Actuators
 
 
 

Precision Control

Electric actuators provide accurate control over damper positions, ensuring optimal airflow and temperature regulation.

 
 

Energy Efficiency

By precisely controlling damper positions, electric actuators help reduce energy consumption and improve overall system efficiency.

 
 

Reliability

Electric actuators are known for their durability and long service life, making them a cost-effective choice for commercial HVAC systems.

 
 

Ease of Installation

These actuators are relatively easy to install and integrate into existing HVAC systems, reducing downtime and installation costs.

 

 

 

Applications of Damper Actuators

Cooling Units

Damper actuators regulate the airflow from cooling units (CRAC units or CRAH units) to specific sections of the data center, ensuring that critical equipment receives adequate cooling.

 

Hot and Cold Aisle Containment

In data centers with hot and cold aisle containment, damper actuators control the airflow within the aisles, preventing hot air from mixing with cold air and improving cooling efficiency.

 

Supply and Return Air Ducts

Damper actuators control the airflow in supply and return air ducts, allowing for precise adjustment of airflow to different zones within the data center.

 

Fire Suppression Systems

In some cases, damper actuators can be integrated with fire suppression systems to automatically close dampers in the event of a fire, helping to contain the spread of smoke and fire.

Installation Precautions for Damper Actuators

 

 

》When using metal gaskets, the load must be uniform to avoid the influence of temperature and deadweight or the stress generated by welding to bring additional pressure to the valve, causing the valve flange and pipeline to deform.


》When the valve is installed in a place with a long pipeline, a support frame should be installed.


》When installing the valve, pay attention to the flow direction of the medium so that the opening direction of the butterfly plate is consistent with the flow direction of the pipeline medium, which is conducive to the self-cleaning effect of the medium flow rate.


》Strengthen the protection of the overall insulation layer of the pipeline network so that the pipe wall temperature is above the dew point, which can reduce the accumulation of low-temperature adhesive dust.
