Damper Actuators and Air Control

Damper actuators are used as an element for controlling air cooling. This can be done either electronically or pneumatically. We decide which kind to use based on the systems specific mechanical functionality. Some of the types include spring return, linear, and rotary actuators, which can be selected based on electrical compatibility.

These actuators can be added onto HVAC systems very easily. The selection process set up by most manufacturers is a fairly simple thing to do with common and consistent wiring and accessories.

It may not be necessary to run the air conditioning system in order to cool an entire building if the outside air temperatures are mild enough and if the building is set up for free air cooling. But since the air conditioner's duct work goes outside, the control system will need to call for free air cooling, which will open the outside air damper and draw in air from the outside.

Conditioned air will then enter the building and force out the warmer air with another outside damper. The actuator will also force out the warmer air as well as keep the cool air inside.

Pneumatic damper actuators are used in multi zone systems, heating, ventilation and other systems. In order to help position the air damper, damper actuators are used in a control system as it receives air pressure signals from the control device. As it gets the signal, the damper will adjust as necessary to allow the flow of air to pass through.

Special mounting kits are used for the damper actuators and are available for many types of units. Usually an internal spring will be used to operate the actuator, allow pressure to build and then complete the air travel throughout the system. Customization is available to adjust the amount of airflow allowed.

Electric damper actuators, which can also be called electro-mechanical actuators, have motors that are used to open and close the damper. Automated systems used these in order to monitor the air flow going throughout the unit.

Electronic actuators use a motor drive that converts to torque in order to control the valve. These are mostly used for multi turn valves. Dryers and ovens are an example of where these can be found. Without this kind of valve system, fresh water and automatic heat would not be available.

Damper actuators often times have a solenoid used to convert energy into motion that will open and close the damper. This makes it easy to control the damper as well as the whole system.

Solenoids are usually made of stainless steel, which helps to fight corrosion and gives it the ability to withstand harsh environments. Most commonly these solenoids are used in commercial HVAC systems.

Damper actuators are very important to HVAC systems. There are many different ways to used them, which makes it fairly easy to find a way to utilize them in most systems. As it is very difficult to say one type is better than another, depending on your application, it should be easy to find one to fit your needs.
