The Condenser: Electric Actuation

The Condenser - Electric Actuation

In this Condenser article, we discuss the benefits of electric actuators. Achieve full automation of your louvers and dampers with electric actuation!

Electric Actuation

Electric actuators can fully automate your louvers and dampers, when tied to an HVAC control system.

Control dampers and adjustable louvers will come with a manual actuator, requiring an operator to adjust the blades by hand. This setup would only work if you could easily access the actuator to make these adjustments. Your louvers and dampers won’t be easy to access. They will be installed all over your building in hard-to-reach places. You'll need actuators that work remotely.

Electric actuators automate blade action. They utilize an electric motor to rotate the driving blade axle, which turns the other blades connected via the linkage. These actuators will require a constant power source to operate. You will need an electrician to professionally install and wire them.

Electric actuators can also be tied to an HVAC control system for fully automated control. Once connected, the system can signal the louver or damper to open and close as conditions change. Blades will open and close remotely, as needed. Sit back, relax, and let your electric actuators control the flow.

Choosing an Electric Actuator

Standard electric actuators will rotate the blades to fully open or fully closed. However, modulating electric actuators can set the blade to rotate to an angle between the two standard positions. Modulation comes in handy if your application requires fine-tuned air flow. Make sure the damper or louver is designed for blade modulation before choosing this option.

Know what you need before selecting an electric actuator:

  • Actuator Voltage - How much power will your actuator need? Will your system have the right power?
  • Modulating - Do you need to modulate blade rotation? If so, how many
  • Power Loss Action – If the actuator loses power, should the blades default to open or closed?
  • Mounting – Will your actuator need special hardware to be installed on the louver or damper? Will the louver or damper fit in its opening with the actuator installed?
