Louvre Cooling Tower
Louvre Cooling tower or air inlet shutter is one of the common components of cooling towers, which functions primarily as an inlet valve for cooling air. The Louvre is commonly seen in the form of shutter-like vents in most cooling towers. The air inlet in cooling towers depends on the type of device (cross-flow or reverse flow) from both sides or from all four sides. Of course, in both cases, louvers with certain specifications are used in the form of multi-blades in various types of fiberglass cooling towers. The Louvre has different types of cooling towers and is divided into two general categories. The new generation of louvers, as you can see in the picture, is made of aluminum and filtered. The use of this model of louvers has become very common today, and the use of the louver filter model has found many benefits today.
What is the role of the Louvre in the cooling tower ??
The Louvre is a vent to allow dry air to enter the cooling tower. There are different types of louvers and they are used depending on the location and the type of cooling tower. Fiberglass and honeycomb louvers are common types of this product in all types of cooling towers . Fiberglass cooling tower louvers are mostly used in blade models with 2 or 3 blades. Blade louvers are also used in various types of circular or round cooling towers, the main material of which is composite. Honeycomb louvers are often made of PVC or polyvinyl chloride. This model is used only in various types of fiberglass and galvanized cubic cooling towers.
In fact, the Louvre is used in a variety of fiberglass and metal cooling towers that are responsible for sucking the necessary air. Inlet air shutters are classified into different types according to the amount of air required to rotate. Louvre sizes typically increase with increasing refrigeration capacity of the device. The dimensions of the louvers can be produced from a height of 30 to 120 cm and a width of 50 to 250 cm. FRP and PVC shutters, like air conditioner vents, let in dry air. The air escapes from the fan stack or oven (upper throat) by passing through the Louvre after the dehumidification process.
What is the use of using a filter in Louvre Cooling Tower?
The use of metal filters behind the air intake louvers in the cooling tower prevents solids from entering the water cycle. The air that is sucked in by the fan or impeller from the Louvre sometimes contains dust, leaves and things that can sometimes cause problems. The use of a metal pre-filter system (aluminum filters) on the back of the Louvre prevents dust from entering. The use of these filters should be designed in accordance with the suction power of the fan. As you can see in the first image, the filters used in the air inlet port have large holes for air suction and filtration.
Types of Louvre cooling towers
Honeycomb Louvre Cooling Tower
Honeycomb louvers have air inlets with honeycomb-like compartments that are mostly used in different types of upstream cooling towers and only in cubic towers. This model of cooling tower louvers has compartments of PVC (polyvinyl chloride) material with a thickness of 600 to 800 microns. This model of air inlet shutters is produced and designed under a fiberglass frame with galvanized blades. This model of cooling tower louvers is mostly located in the system of cubic cooling towers in the upper part of the pan, and one of its main advantages is that contaminated particles do not enter the cooling tower. These models of cooling tower air shutters have very good air suction with standard speed.
Benefits of Cool Tower Tower Honeycomb
Low static pressure drop and no high pressure on the fan
It has an inlet air filter against the entry of foreign objects
Has a detachable frame and easy to replace
Economical and periodic replacement every 2 years
Ability to wash with car wash jet
Temperature tolerance of 60 ° C
Blade cooling blade tower
This Louvre model has blades that allow air to enter the cooling tower from the space between the blades. Blade louvers are used in various types of cubic and conical fiberglass cooling towers and are often made of fiberglass material and are used as 3 or 4 blades in different types of upstream cooling towers. Cooling towers or shutters are usually installed in the form of large blade panels on both sides of the cooling tower if they are located in cross-flow tower systems. The thickness of fiberglass louvers produced by Damagester Company varies between 6 to 8 mm.
Advantages of a cooling tower blade blade
Fresh air enters and sucks at a certain rate at a suitable speed
Ability to wash with acid and easy descaling
Easy to replace
Lightweight and durable (lifespan over 10 years)
Ability to repair with fibers and resin
With the ability to install metal filters inside
Louvre Cross-cooling tower
In many types of cooling towers that have a reciprocating air intake system, air suction valves or valves are usually placed on both sides. In this model of cooling towers, which are also known as Abara cooling tower , blade louvers with a large number of blades are used. This model sucks a variety of air cooling towers in a transverse flow perpendicular to the water flow through the air inlet valves. The air intake valves of this type of industrial coolers are made of fiberglass material and in most cases their height reaches about 200 cm. Of course, in many types of metal cooling towers, the suction type of these valves with metal materials such as galvanized and aluminum is also used.
Price of Louvre cooling tower
The price of a Louvre, like many types of interior components, depends on a number of factors. One of the important and influential factors in determining the price of the Louvre is the type of Louvre, dimensions, material and materials used in the production of this piece. In fact, fiberglass louvers are far more expensive than honeycombs.
Adding an aluminum air filter on the back of the Louvre also increases the cost of this equipment. In each 1-year period, the Louvre is in need of service and washing due to constant contact with environmental pollutants. The life of fiberglass used in the production and manufacture of Louvre is about 15 years and PVC is about 3 years. The main reason for the short life of the Louvre polymer is that it does not have anti-UV properties against sunlight.
