Dampers: One of the Most Efficient Parts of HVAC System

Selection of a right damper is imperative for getting assured about the performance of the air flow systems. The dampers help in maximizing the energy efficiency and minimize the cost of installation. Volume control damper, Fire damper, and Duct Damper are the various dampers manufactured.

Volume control dampers and their features

Among the specified dampers, volume control dampers (VCD) are considered to be among the essential requirements in the HVAC systems. A volume control damper proficiently balances the airflow in varying areas.

Being light in weight in comparison to the steel dampers, they are highly resistant to corrosion.

How to know if VCD are of a high standard?

The best volume control dampers have low leakage when closed which impacts the performance of the HVAC system. Apart from this, the damper must be easy to operate and must not create much resistance. The series VCD satisfy the requirements that reflect their performance excellence. These are designed by the manufacturers for smooth, quiet and reliable operation after being engineered and tested.

As the HVAC performance depends on the airflow, the top leading manufacturers design the VCD series that meet the highest standards. These are available in square, rectangular and round style. The rectangular and square style VCD is opposed blade design that controls the airflow with low or no turbulence creation in the duct work. The basic advantage of these dampers is it can be installed in either direction of airflow.

Motorized volume controls dampers and its features

The motorized volume control damper with the opposed blade operation closing system is designed for controlling airflow as well as pressure in HVAC system. In this damper, the blades are formed with single skin construction along with grooved blade tips that produce an interlocking blade closure either manually or automatically. The dampers operated manually are found with standard and lockable quadrant assemblies which allow it for motor operation without adding any other components.

So from the above one can conclude that volume control dampers are the essential requirement of the HVAC systems. HVAC performance depends upon the operation of the volume control dampers as this can be used in the areas having high humidity or in the coastal areas where the steel units are affected easily.
