What is a fire damper?

Fire dampers can be found in ducts, air transfer openings, and most places where fire-rated constructions like floors, walls, or other fire obstructions are constructed. If fire dampers are not installed, the fire can easily spread, causing serious damage to property and people present in that environment. The reason behind the concept of compartmentation is to stop the fire from spreading to nearby locations. This method helps a lot in limiting the outburst of fire and therefore reducing damage to property and people. So, in a nutshell, a fire damper is a tool used to stop the outburst of fires. If you’re looking for installation, the best aluminium and technical engineering factory –Tecnalco in UAE can help you in making the appropriate decision and install the Fire Dampers most appropriately to avoid the spread of fire.

Why do we need fire dampers?

One of the most harmful hazards is an outburst of fire that has the potential to be even life-threatening. In uncontrolled situations, fire can roll out through ventilation ductwork and can install systems that are efficient enough to control the fire. It is important to furnish your ventilation ductwork with superior and sturdy fire dampers that can stop smoke from outspreading and hence ensure safety for escape way out.
Fire is not the only hazardous thing in such cases. Gases and smoke released from this fire can pose a real threat to the environment and respiratory health of the people present. There are different chemical reactions taking place in our environment and the smoke and gases can be really dangerous for our ecosystem, destroying its balance in many ways. These gases travel at a high rate and even the smaller amounts can be highly fatal for human beings and animals. Fire dampers can be fitted with special seals that will help in restricting fire along with these gases thus, saving the environment and mankind in many ways.

Operation of fire dampers

Fire dampers can be operated in a very simplified way. They are very convenient and systematic as they close the moment temperature rises above the threshold limit to restrict the fire outburst. The fire dampers aluminium technical engineering factory- Tecnalco in UAE makes installation for the special quality of fire dampers fitted with a fusible link that can be selected according to the desired temperature. After this temperature is crossed, the damper automatically closes.

Fire dampers are very versatile as they can be pneumatic, electrically activated, or manually operated. Electric and pneumatically activated dampers are fitted with fusible tube links that release and block operating voltage to the spring return motor, permitting the spring to close the damper blades. They will open automatically on the change of the fire and the motor is re-established with the operating voltage. In the case of spring-operated dampers, a fusible link will release, permitting the spring to close the damper blades. The fire damper requires to be reset manually when the fuse is changed.

Installation of systems by Fire damper manufacturers in UAE

The installation process should be carried out by trained professionals only. Besides the knowledge about the installation, they should know about the usage of the building’s HVAC and the wiring system. Fire dampers require a proper strategy to be fitted. The location of installation for these devices is very specific to make sure the fire dampers close the moment the outburst starts and prevents it from spreading.

HVAC dampers help to monitor air volume by conducting systems and regulate them. In the ductwork with low to medial airflow velocity, control dampers are normally mounted. It can be used to produce positive shutdowns and also to monitor HVAC low-leakage systems automatically.

Dampers are often used in zoning and zone control systems. Air dampers are used to regulate material movement in industries that move gases and liquids through pipes and pipes.

Air Control Dampers come in a variety of sizes and shapes, including square, circle, and rectangular backdrafts, and it is critical to choose the right one for the task. The position, configuration, and function of a damper decide the form of the damper. Zero leakage bubble-tight dampers, volume control dampers, motorized volume dampers, and so on are examples of such dampers.

In this blog, we will discuss volume control dampers.

The Volume Control Damper is a device that regulates airflow through an air duct. Complete manual quadrant or motorized actuators are available with this unit. Volume Control Dampers are ideal for systems requiring air control and can be made of galvanized steel, stainless steel, or aluminium. If you are familiar with the characteristics of volume control dampers, it will be simple to choose from the huge list of dampers offered by VAV manufacturers in the UAE. The size of the volume damper and the area where it will be installed are often the most important factors to consider when selecting one.

The Volume Control Dampers help regulate the volume of airflow to the other sections of the device. These dampers can be fixed within the duct itself and can be manually or automatically. In determining individual HVAC technologies and entire systems, an understanding of the interdependence of HVAC technology between them, as well as other electric loads and maintenance and operational practices is fundamental. As with lighting, HVAC systems have broad and varied technology and potential configurations.

These dampers can be immovable or fixed within the air conditioning system. The volume control dampers’ doors can be opened and closed manually to change them. The ash-pan is also accessible through the volume damper, which allows for the removal of accumulated clinker and the removal of ashes.

From their wide range of products, motorized volume control damper suppliers can fabricate and supply a number of sizes and styles of quantity dampers. Volume Control Dampers made of stainless steel and aluminium sheet are recommended because they have a higher inherent resistance to corrosion and abrasion.
They are ideal for places where there is a lot of moisture and hydration because of the material and construction.

These dampers are simple to adapt to the surrounding temperature and humidity, making them effective at reducing power consumption. The use of the proper volume control damper lowers energy bills. They are effective at lowering the pressure in zone controls, which increases HVAC performance.

Volume control dampers are available for either parallel or opposed blade operation, with each design having its own set of characteristics depending on the type of operation. Parallel blade dampers are designed for all blades moving in the same direction and parallel to one another. When the damper has two positions, open and close, the parallel blade orientation is used. Opposed blade dampers are used on dampers that modulate airflow and are built with blades that pass in opposite directions. When it comes to the location of the dampers within the air conditioning system, they are either fixed or immovable.

The door of the volume control dampers can be opened or closed manually. They even make it possible to empty the ash-pan and dispose of the clinker that has accumulated. The volume control damper’s primary role is to:

• Control airflow inside a duct.
• Aid in the maintenance of a set temperature. A volume control damper is important for the heating and cooling of the building in the HVAC system. It controls the temperature.
• Maintain the necessary pressure.

The dampers consist of several plates, blades, axles, coils, blade fasteners, and other components adapted to the particular application of the damper. The damper’s actuator is used to control the damper’s location using signals from the building automation system, thermostats and controls, pressure switches, and relays. The capacity of the actuator to sufficiently open and close the damper, as well as the amount of torque it can provide, are used to determine which actuator to use. This is usually determined by the following factors:

• Dimensions of the damper.
• Air velocity through the damper.
• The static force acting on the damper.
• Form of damper blade – parallel or opposed

Always check the seller’s certification label, positive customer reviews, and company credibility before purchasing a damper. Leading volume control damper manufacturers, such as Technalco, are known for producing high-quality products at a reasonable price.

The fire dampers are key passive fire safety devices and are used in the sector of air conditioning, ventilation, and heating. Generally, a fire damper operates when heat from a fire causes a room’s normal temperature to increase by 165°F, i.e., it is designed to close heat automatically. The fuse connected to the damper melts allowing the door of the damping door to close. In particular, they are situated in a duct at the intersection of the fire barriers in building zones, such as divisions at the point of penetration of the duct, to maintain a wall or floor fire rating. The fire damper guarantees the safety of the current lock.

The fire damper protects the current barrier, preventing fire penetration until temperatures exceed the barrier’s fire-rating level. Its main purpose is to prevent fire from spreading from one side of a fire-rated barrier to the other. The damper is built to withstand high temperatures for as long as possible, and it is manufactured to a high standard of integrity.

When room temperatures reach about 165 degrees Fahrenheit, the fusible component in the fire damper melts, allowing the door to shut. This helps to keep the fire from spreading and causing as much harm as possible. Property owners should be aware that rooms that are regularly heated to 165 degrees or higher would need fire dampers with higher melting point fusible connections.

By preventing the spread of fire by heating, ventilation, and air conditioning ducts, the damper aids in preventing a fire from spreading throughout the home. They also help prevent smoke from spreading through the ductwork in the event of a fire.

In a residential environment, there are two types of fire dampers to choose from. Dynamic and static fire dampers are two types of fire dampers.

Dynamic Fire Dampers

These dampers are built with a spring-loaded design and continuous fan use as vertical barriers. The air pressure generated by the ventilator helps to unlock a loaded door system, enabling the ventilator to stay in operation quickly.

Static Fire Dampers

In contrast to dynamic fire dampers, static fire dampers are installed as horizontal barriers with a curtain-like structure. If a device with static fire dampers is triggered and the door of the damper is decaying due to the weight of the damper, the HVAC fans are set to turn off. Whatever these systems are in use, owners of the property shall contact HVAC technicians to inspect the dampers and remedy any harm at the earliest opportunity.

Fire dampers should be checked and maintained on a regular basis due to their vital safety features. On models with fusible connections, all that is needed for fire damper maintenance is to check that the fusible connection is still present and not covered in grime and dust. Fire dampers with circuits should be tested more frequently. Even if the tests are positive, the dampers should be physically inspected on a regular basis.

Sand Tra犀利士 p Louvers Filter

Sand trap louvres are normally located at the first point of the air intake and are an essential part of any air handling device. Sand trap louvres, as their name implies, prevent sand from accessing the air intake unit or equipment rooms, preventing damage to the equipment’s moving parts. In desert or sandy areas, they are also used for ventilation in parking lots, warehouses, generator rooms, and fan rooms, among other places. In the presence of high dust concentrations, it has a high degree of sand and large dust particle separation. The sand trap louver installation is maintenance-free thanks to the vertically arranged blade parts and holes for sand drainage. It is made to separate big sand and dust particles from the airstream at low speeds, preventing unnecessary dust loading in traditional filters. It is not meant to be used in place of traditional filters. Sand trap louver installation specifically to remove sand and dust from the air. It is efficient and appropriate to use for air handling unit ventilation and inlet ducts. Since it comes with a complete aluminium extruded profile unit, the assembly is corrosion-resistant and suitable for different weather conditions. For sand trap louver installation, filters and dampers are available as options.

We need the means to include the free area and First Water Penetration in a meaningful way to better assess a louvre’s capacity. Since the ultimate goal is to get maximum air via the louvre, we want to determine the permissible air volume through the louvre (cubic feet per minute or cfm). The AMCA Standard 500-L Laboratory Methods for Air Louvers Testing for these concepts are protected by the test methods.

The following example compares two louvres with different performance characteristics for a 48″ wide x 48″ high wall opening:

We could conclude that Louver 2 is better than Louver 1 for getting more air through the louvre because it has a larger free region.

For a 48″ wide x 48″ high wall opening, Louver 1 has a 45 percent-free space. The gross free area is 7.2 square feet (45 % x 16 square feet of wall opening). For this louvre, the tested First Point of Water Penetration is 1190 feet per minute-free area velocity. We should account for any difference in the airflow through the louvre by using a safety factor – we have selected a 25% safety factor. With the safety factor, the geometry velocity will be 25% less than 1190 fpm, or 893 fpm (1190 x .75). By multiplying the louvre-free area by the design velocity, we can now calculate how much air can be safely passed through the louvre ( 7.2 sq ft x 893 fpm). Louver 1 has a volume of air of 6424 cfm as a result.

When we do the same calculations for Louver 2, the result is just 4781 cfm (with a 25% protection factor). The amount of air passed into the same opening size is 25% lower. Louvre 1’s a safer option because we can deal with the pressure drop at higher airflow rates!

The majority of manufacturers list the airflow resistance of their louvres on their websites. Based on the blade and frame shapes and angles, each louvre will have a slightly different resistance.

Most louvres do not deviate significantly from the graphs, unless they are built for extremely high air velocities, such as wind-driven rain louvres. We can measure the resistance for each louvre at the design velocities and see that:

Louver 1 – at 893 fpm-free area velocity, will create 0.090 inches w.g. of static pressure

Louver 2 – at 563 fpm free area velocity, will create 0.055 inches w.g. of static pressure

The two values must be suitable to the design of HVAC systems, and our Louvre 1 is the best option, even if the area is less free of charge. For most applications, a reasonable thumb rule is to remain below 0.2 inches w.g. static pressure.

The property owners recognize the importance of adequate steps or measures against fire damage. Fire damper manufacturer in UAE can install the equipment in different areas at home or in a commercial building. Although the damper is not the only product to look for, it is important to inspect the different other parts of the system to work efficiently in the misfortunate event of a fire. The latest HVAC air distribution products in UAE include the fire dampers as the pre-installed system. It is important to get the periodic inspection and repaired and understand their working.

How do they work?

Fire dampers begin the operation when the room temperatures go up to 165°F. This is the point at which the fuse of the fire damper will melt and the door closes automatically. The property owners need to understand that the places at which the fire dampers are installed usually do not get this temperature and have higher melting points than 165°F.

What is the necessity?

It is important to incorporate the fire safety equipment in the ductwork of any house or office. The exhaust valves exporters in UAE give different options to choose from and install the equipment to spread fire during an accident. The fire spread is retarded to spread to the rest of the home and the smoke doesn’t travel through the ductwork in any fire event.

Fire Dampers in Ventilation Systems

The fire damper manufacturer in UAE intends to install the systems in ventilation areas as the cut-off baffles that separate the fire zone from the rest of the building. The major function of KWP type of fire dampers is to restrain the fire spread, temperature, and smoke. It additionally uses the actuators for use in the mixed ventilation systems. There are fire dampers available for vertical and horizontal installation that is used in walls and ceiling-fixed AC systems.

A fire damper is constructed, manufactured, and tested as per the standards for Ventilation for Buildings. The sensitivity of the equipment is checked by the tests following the guidelines for the testing and service installation. The usual construction of a fire damper consists of two bodies manufactured using the galvanized steel that is separated by the insulated dividers with a thick fire-resistant material. Fire dampers are manufactured for use in chemically aggressive surroundings, such as laboratories, the food industry, the chemical industry, or similar platforms. In this case, the steel components are replaced by acid-resistant steel that doesn’t corrode or wears away soon.
