There are many volume control damper manufacturers in UAE. The challenge is to choose from different types of damper systems. That said, this article is for you and can really help you make the right choice.
Buildings with numerous rooms, like offices or schools, may have huge and intricate HVAC systems. To supply air to each of these regions, more than just ductwork will be required. Dampers are used in this situation. Devices with blades enclosed in a square or rectangular framework are called dampers. The style and type of the damper can affect how this design is constructed. For example, some dampers may have a rounded frame to fit into ducting that is rounded. You will also find Fire damper manufacturers in the UAE who are there to provide you with high-quality dampers at a budget-friendly price.
There are several distinct types of dampers, each of which has a particular function despite having a similar design. The five types of dampers that are frequently encountered in HVAC systems are listed below.
- Control dampers
The airflow through the system is regulated by control dampers that are positioned at various locations in the ductwork. These dampers can also be modified for usage in air mixing zones to heat and cool the air. Many times, throughout the day, control dampers will completely open or completely close their blades to fulfil their task.
- Balancing dampers
Rooms connected to the ductwork have balanced dampers installed to control air pressure. Uneven air pressure can result in minor inconveniences for residents like slamming doors or sporadic air rushes, but it can also result in more serious issues for the overall system. An unbalanced space may be harder to heat or cool, which puts an excessive amount of stress on the air handling devices.
Technicians balance dampers by changing the angle at which the blades of the damper are angled while measuring the air pressure in the space. The blades of the balancing damper are locked in place to preserve the required air pressure once the proper air pressure has been identified. You can unlock them for future alterations.
- Backdraft Dampers
To limit airflow to one direction only, backdraft dampers are fitted in particular locations within the duct system. Each blade of these dampers has a shaft attached to one end of it. The blade is transformed into a flap in this design, and it only opens when the air is moving in the desired direction.
The blades of a backdraft damper will close if no air is travelling through them or if air starts to move in the opposite direction. Installing a counterweight in a backdraft damper might help or hinder the opening action. These dampers are not equipped with actuators.
- Multi-Zone Dampers
Multi-zone dampers are utilized in structures with a single air handling unit, such as modest office buildings or single-building schools. These are substantial assemblies of dampers, each of which is connected to a different zone. Multi-zone dampers are duct-connected devices that regulate the airflow throughout the entire system. A multi-zone damper will have several actuators, each of which will control a different zone. These dampers are frequently sold as a whole package with the air handling unit.
- Industrial Dampers
Industrial dampers are made to stand up to extreme air pressures and constant temperatures of over 250°F. To survive harsh environments, they are constructed from thick gauge materials, mainly steel. For ultimate durability, each component is securely welded into place.
These dampers are frequently used in power plants and manufacturing plants, sites with significant airflow requirements. The industrial ones are the heaviest available dampers.
Conclusion
There are various types of dampers available, and each type has a specific function. With the exception of the single multi-zone damper, which is installed with a single air handling unit, your HVAC system may need that all of these dampers work together. It's crucial to understand what each damper works and how it fits into your HVAC system even though you will probably use all of these dampers.
