How to appropriately size a Belimo damper actuator 

 

Determine the type of damper: 

Choose the appropriate damper type, such as an air damper, fire damper, or smoke damper. Different damper types demand different amounts of torque. Utilised to control the flow of air ventilation systems through the damper. It is an electric actuator with remote control capabilities that may be used to open or close dampers or valves, changing the flow of fluids or air in response to external factors or human inputs.  

 

 


Calculate the torque requirement: 

Find out how much torque is needed to operate the damper. This can be accomplished by taking into account the air pressure, damper size, and other application-specific elements. The required torque is commonly expressed in inch-pounds (in-lb) or Newton-meters (Nm).

 

Consider the control signal: 

Find out what kind of control signal will be utilised to activate the damper actuator. A variety of control signal alternatives, including on/off NM24A, modulating (analogue) NM24A-SR, or digital communication protocols like BACnet & Modbus are available for Belimo actuators. Select an actuator that works with the controls you have.

 


Select the appropriate actuator series:

A variety of damper actuator series with various torque outputs are available from Belimo. Examine the Belimo-provided technical details and torque ratings for each actuator series. Make sure that the torque rating of the actuator you select is equal to or higher than the torque requirement determined in step 2. 

 

Consider additional features: 

Check to see whether you need any additional actuator features or functions, such as feedback control, spring return (fail-safe), or programmable stroke settings. Choose the characteristics offered by Belimo that best fit your application from the alternatives available.

Consult Belimo's technical documentation: 

For further details on each actuator model, consult the product catalogue, datasheets, and technical literature from Belimo. To assist you in making an informed choice, these sites will offer you specifications, measurements, wiring diagrams, and other pertinent information. 

 

Seek expert advice if needed:

Consider speaking with a Belimo representative or an experienced HVAC specialist like iACS for advice based on your unique application if you are unclear about the sizing process or have specialised requirements. Keep in mind that a damper actuator's proper sizing is essential for optimal performance and effective use.
