Difference between Diffusers and Grille/registers
Grilles and registers are completely different from diffusers. They have different functionality. Grilles/registers are placed to obstruct the entry of unwanted materials like dust, dirt and other particles into the HVAC system while the purpose of diffusers are to uniformly dispense air towards different directions of an area. Through air diffusers air quality can be maintained.
Ensuring a uniform HVAC airflow
By regulating the flow of air you create a comfortable environment in the places where your stay. This not only makes the working of HVAC system effective and efficient but also reduces your utility bills.
Few step to be taken for ensuring an even distribution of air through HVAC system:
Monitor and understand the temperature of different rooms – By identifying which rooms are too cold and too warm you can rectify the air distribution easily.
Install HVAC diffusers – if it is already installed check if it is functioning correctly. Also check whether it is obstructed by anything.
Adjust the diffusers – according to requirement adjust the modes of the diffusers for ensuring good distribution of air.
Use of Essential oils
Essential oils can work well with HVAC system. If essential oils are used along with air diffusers then more comfortable ambience can be maintained. Air diffusers spread the properties of essential oil throughout the room, thereby reducing the growth of moulds and improving the smell of the area.

While designing an air handling unit, it is important to consider the parameter of humidity. A range of 45% – 55% relative humidity level should be maintained for the comfort. At the times of summer or winter, the humidity level of the air goes down, causing discomfort to the occupants inside. This is where we find the importance of a humidifier in an AC system. The humidity of the air can be increased or decreased using humidifier or de- humidifiers.
There are various types of humidifiers available such as,
Spray Type humidifier, which got a header and spray nozzles that spray water with a pressure of 15 psi.
Steam Grid Type Humidifier, which has holes on its pipe for steam distribution. The water is conditioned to avoid odor discharge to the room.
Steam Pan Type Humidifier, which has a pan and a heating coil to heat the water in the pan. This increases the humidity level of the room.
In HVAC systems, different types of air distribution devices are available such as grills, registers and diffusers. Diffusers are of various types such as,
Ceiling Diffusers
These diffuser types come in round, square and rectangular shapes. They consist of inner cones made of vanes, which are arranged in different directions. A square diffuser is more common for supplying air. They are normally mounted at the center of the conditioned space and provide shorter throw for conditioned spaces with low head space. The air is discharged in all directions through the concentric air passages. The deflecting vanes change the air distribution pattern.
Slot Diffusers
Slot diffusers are mounted on the sidewalls or in the ceiling. Linear slot diffusers are used for supplying both the supply air and return air. They are suitable for large open- spaces.
Jet Nozzle Diffusers
They are suitable for supplying heated and cooled air in large areas. These can be adjusted to make the airflow in any direction. They have advantages for long distance air supply, low noise levels and come in various sizes and colors. They can be installed anywhere like a sports hall, airports, and shopping centers or at indoor markets. Contact Tecnalco for a professional jet nozzle diffuser installation anywhere in UAE.
So what will you prefer; a humidifier or diffuser?
Humidifiers increase the humidity of a room or a building. They are used in medical facilities like ventilators to make patients comfortable. Humidifiers are large and are connected to a HVAC system. It is really helpful at dry or hot climates, when the humidity level goes down.
Diffusers are used as return air vents to make conditioned air in to a space, evenly distributed and with minimum noise. HVAC diffusers reduce the velocity of the airflow from outside and direct to ensure an effective mixing with maximum benefits and less noise. So rather than a humidifier, diffusers can add the benefits of air conditioning for a space.

The word ‘dampers’ refers to products set up in HVAC ductwork to keep flames from propagating in the ductwork. From a safety point of view, it is essential to stop the occurrence of smoke or fire spreads at commercial buildings. As a Aluminium Technical Engineering Factory Tecnalco -UAE, we know how significant it is to use the product commercially as well.
Installed in HVAC system ducts, automatic fire dampers would automatically shut one or more doors in the damper when a rise in temperature is detected. This will keep smoke or fire from spreading through the ducts to the other areas of the commercial building, which uses this passive fire protection device. The importance of using this product is evident from how it works. Nevertheless, in the capacity of being a Aluminium Technical Engineering Factory Tecnalco , we will take a closer look at this topic.
Reasons to Use Fire Dampers at a Commercial Setting
Active fire protection products such as sprinklers can reduce the speed of spreading fire and help with occupant evacuation. However, those forms of fire protection devices alone cannot keep gases or smoke from spreading. For your information, one of the leading causes of unnatural death in commercial fire occurrences is the act of smoke or gas spreading. Operating passive fire dampers do not require the utilization of electricity. Instead, in the case of an increase in temperature, a thermal element or core would melt to allow for spring-operated damper doors or blades to close. You may want to go for horizontal or vertical damper options, according to how these shut the ducting system. Each damper type suits different applications.
It takes only a few seconds for a tiny flame to just grow and be a major occurrence of fire. Cutting off all the possible passageways where flames can travel will allow containing the situation to a single location. This will help to ensure that a building is fireproof. Being fireproof means that you will have one less thing to worry about even on holidays.
On the other hand, the utilization of motorized smoke fire dampers is to prevent the propagation of smoke through the ventilation system of a building. The dampers are typically situated in the ductwork and work by shutting off at the time of smoke detection. As with a fire occurrence, smoke is also likely to propagate fast through a commercial building. In a fire incident, one of the leading reasons for death is smoke inhalation. It is important to keep smoke inhalation from happening to keep your building occupants safe at the time of evacuation. This is where motorized smoke fire dampers have a big role to play.
Install The Best Fire Dampers Today for Your Commercial Building
Are you planning on building an HVAC or ducting system? If so, be sure to add fire dampers to your plans. When you have any doubt about which damper variety to choose, consider contacting a Aluminium Technical Engineering Factory Tecnalco as well. For instance, we offer high-grade fire and safety products as well as have competent staffers to help you pick the right damper for your building or application.
A sound attenuator is also called a sound trap, duct silencer, or muffler. It is a noise control system of the Heating Ventilating and Air-Conditioning (HVAC) network that is designed for the reduction of noise through the ductwork that gets either from equipment in any building or occupied spaces.
There are different designs and types of HVAC duct silencers and sound attenuators in a system offered by Aluminium technical engineering factory- tecnalco. You may select from a wide range of customized or standard sound attenuator systems for residential or commercial industries that satisfy the needs of the application. The noise caused by HVAC systems becomes too high and the ventilation areas of buildings, enclosures, and equipment rooms become very noisy. The controlling measures include silencers and louvers into the system design that makes the space free from any additive noises. HVAC systems are noisy with the sounds of the electrical and mechanical devices. There are rectangular and circular sound attenuators available for absorbing the sound in the air stream and removing the HVAC noise. The sound produced by HVAC systems is very distractive and the proper installation of sound control systems can ensure the smooth and noise-free working of systems.
Cause of Noise
There are ample reasons for which HVAC systems can become noisy. These systems have an in-built sound absorption technique embedded for keeping the sound low. There are millions of air pockets contained in the Sound Attenuators Manufacturers in UAE. that reduce the noise with the absorption of the passage of acoustic energy. The fans also produce noise with the air vibration and movement of fins. The pressure drop causes the air changes in the system that is a cause of producing the annoying noise. The loose fixing of bolts and nuts even produces a loud noise.
Types of Sound attenuators for HVAC Systems
Cylindrical attenuators: These are fitted in the ducts for silencing the noise from inside. These come with a spinning head with a tail that has the shape of a cone. The circular attenuator has two walls.
Rectangular attenuators: These are fitted over the HVAC system for noise reduction. These include dissipative silencers delivering acoustic energy with sound-absorbing media installed inside them.
In the interior wall of the sound attenuators is the insulation made for reducing the sound to a minimum level. The noise is reduced and the pressure changes in an HVAC system are maintained for making the system flow with ease.
Working of a Sound Attenuator
Sound attenuators are used as an important part of the HVAC system and these are installed to get the best effects for noise cancellation. The Sound attenuators are suggested to be installed by aluminium technical engineering factory-tecnalco, at the time of installation of the HVAC system. The insulation varies in thickness depending on the frequency of the sound produced. Sound attenuation is increased by the enhanced length of the attenuator that controls the HVAC system pressure. Regular maintenance of the system is carried out for reducing the noise and maintaining a check that there are no loose fittings in the maintenance systems.
The silencers are backed by independent testing systems in the laboratory and have applications in the following areas:
Commercial, Institutional or Industrial HVAC duct systems
Air handling units
Cooling towers
Fan Inlet and Discharge

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 Trap 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:

Free Area for 48″ x 48″ (square feet)
First Point Water (fpm)

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.
