(Louver damper)

Louvre Dampers are the essential components of many HVAC systems (Ventilation, Heating & Air Conditioning). HVAC refers to the set of processes and technologies related to heating, ventilation and air conditioning. Since adjustable metal blades can be opened or closed to control the airflow, it is commonly used in canalize to adjust the fresh air to buildings, and at the same time prevents unwanted advances and protects very well against inappropriate atmospheric conditions. The technical and specialized team of the Apadana Tower Industries understands the importance of choosing the proper damper type for your specific needs. To help you understand, in addition to the physical presentation of this product, we have collected details on how Louvre Dampers, which we serve.

✔ What is Louvre? 

 On the other hand, louvres are placed in the outer part of the building to pass the fresh air and protect the HVAC system against the penetration of water, soil and garbage, such as rain and leaves. Typically, they are installed on the air input and have stable blades that are not closed. This means that if needed to interrupt the air, a secondary damper is required. For example, the HVC’s NCA S800C model – which is heavy extinguishers Damper?
Damper is a valve that stops or adjusts the air flow inside the duct. There are several types of dampers, each of which are for certain uses. Like fire slippers, preventing fire and smoke in the event of a fire. Other types of sound control slippers help the air flow in the building as part of

the HVAC system. Also, the type of non-returned dampers that opens with the flow of air and are closed by gravity and are used both in commercial and residential places. Other advantages of this type of damper minimize the heat dissipation from the inside of the building when a system is inactive. Dampers without return if properly adjusted do not require a handy engine or input.

Types of Louvre Dampers 

 Dampers are made of metal and are usually square, circle or rectangle. Some industrial slippers are designed to reduce pressure or are recommended for use in specific HVAC systems. Demperators are usually made of aluminum or steel. Loaders may be customizable or suitable for applications that need no noise control. 

 Types of dampers 

 Dampers are categorized as industrial control products, rebuilding, balanced, bubble, isolated or drainers. 

1. Back dampers with galvanized steel frame and airfoil blades are extruded aluminum. These blades provide a better strength by reducing noise and static pressure. 
2. Balanced rear slippers are usually made of galvanized steel. They are designed to meet the applicable requirements based on temperature, pressure or speed. 
3.  Industrial slippers include bubble dampers, rounded insulators and dull drain dampers. 
4.  Bubble slippers in applications that need to be closing. Are used. The ability to shut down in their hard conditions may be eligible for use in nuclear power plants and tested according to ASTM and ASME standards. 
5. Round insulation slippers are made of carbon steel and have a butterfly blade. They create a very low leakage in both the HVAC and process systems. 
6. ⬥Round discharge slippers are also made of galvanized steel, but are designed for use on the drain side of a pivot flow fan. These slippers prevent fan shutdown and can tolerate pressure and speed in multi-fan applications. 

Louver types

 There are four main types of industrial Louvers: fixed, customizable, combination and air measurement. 

1. Loaders Fixed with angular blades or airfoil that may provide weather protection. Sound weakening.
2.  Adjustable loads with airfoil blades are also available.
3.  Combined lines have blades that begin to open at a level of static pressure and completely open at the other level. They may have dorsal damper blades and have a all-aluminum structure for corrosion resistance. 
4. The air measurement leases have vertical blades that prevent water entry.

The important thing here is to pay attention to temperature, pressure, gas chemistry, flow rate and pressure drop and particles. Additional considerations include an environment where the damper is created. Some dampers are better designed for outer environments that rain, cold and heat can affect damper blades and cause obstruction, swamping and failure. 

 And finally, we will have 4 types of Louvre Dampers: 

1.  WG-JZ-S: Louver of external air and multiparty damper with opposite performance blades, both galvanized steel. 
2. WG-JZ-P: Louver of external air and multi-air dampers with parallel performance blades, both galvanized steel. 
3. WG-AL-JZ: Louver of external air from aluminum and multi-air dampers with opposite yield blades from galvanized steel. 
4.  WG-AL-JZ-P: Louver of external air from aluminum and multi-air dampers with parallel performance blades of galvanized steel
