Overview: Volume control dampers are specially designed for use in heating, ventilating and air conditioning systems for volume, and flow and pressure control of air within the ducts. Volume Control Dampers allows even distribution and flow control of air at high duct pressures and are suitable for various type of HVAC applications. Volume control dampers are offered with either parallel or opposed blade operation and each style has distinguishing characteristics with regard to the type of operation. Parallel blade damper are constructed so that all the blades are moved in the same direction and are parallel. The parallel blade orientation is used when the damper operates in two positions open or close. Opposed blade dampers are constructed so blades next to each other move in opposite direction and used on dampers that modulate airflow. If we talk about the position of the dampers inside the air conditioning system is either immovable or fixed. They can be adjusted manually by opening or closing the door of the volume control dampers. They also provide access to remove out the ashes collected in the ash-pan and eliminate the clinker accumulated. The basic function of volume control damper is
- It regulates flow of air inside a duct.
- Temperature control: It helps in maintaining the desired temperature. A volume control damper is an essential part of HVAC system that regulates the temperature and provides efficient heating and cooling service to your building.
- Pressure control: It maintains the desired pressure.
The dampers are designed and are constructed from a variety of frames, blades, axles, bearings, blade linkage and other parts to suit the particular application for the damper. The actuator in the damper is used to control the position of the damper based on signals from the building automation system, thermostats & controllers, pressure switches and relays. Actuator selection is based upon the ability of the actuator to adequately open and close the damper and the amount of torque the actuator can supply. This typically depends upon the following:
- Overall damper size.
- Velocity of air through the damper.
- Static pressure against the damper.
- Damper blade type – parallel or opposed
KAD’s volume control dampers are designed to balance air to individual areas and it is considered as one of the prominent and renowned volume control dampers manufacturers in the competitive market of the UAE and these volume control dampers can be manufactured with galvanized steel, stainless steel and aluminum materials.Tags: Volume Control Dampers Manufacturers
