Industrial Fans – Chemical Industry

Biomass boiler packages service the wood industry—burning waste products ranging from excess wood, wood chips, coconut husks, or even cocoa bean shells to create steam that can then be used to generate power. Fans serving these types of industrial applications need to have a rugged construction to be able to handle the harsh operating environment introduced by the high-temperature biomass boilers, and Canada Fans fans continue to stand up to the test. All housings are continuously welded using heavy gauge, reinforced steel, and suitably braced to prevent pulsation. Wheels and blades are manufactured with a heavy-duty, robust design.

Radial Blade Fans

In addition, the range of products used in the boilers means that the fans must handle often-dirty airstreams. In these cases, straight radial blade designs are used to alleviate the potential operational problems that can be caused from buildup on the blades from materials coming through the fan. Canada Blower also understand the importance of designing a product that could meet the needs of varying climates and other environmental challenges.

Axial Fans & Axial Ventilators

Canada Fans fans are the finest quality blowers available for efficient movement of corrosive, humid, or polluted air, gases, and fumes. These fire-retardant and corrosion-resistant plastic fans are specially designed and especially suited for hostile applications where coated metal blowers typically corrode. Canada Fans fans are proven thoughout the world and clearly recognized for superior quality, reliability, and efficiency.

Axial Flow Fans

The axial flow fans are widely used for providing the required airflow for heat & mass transfer operations in various industrial equipment and processes. These include cooling towers for air-conditioning & ventilation, humidifiers in textile mills, air-heat exchangers for various chemical processes, ventilation & exhaust as in mining industry etc. All the major industries use large number of axial flow fans for operations, such as:

– Power Generation Facilities

– Petroleum Refining & Petrochemicals

– Cement Industry

– Chemicals & Pharmaceuticals

– Fertilizer Production

– Institutional Ventilation, etc..

Fiberglass Reinforced Plastics (FRP) provide the desired non-corrosive quality to the fan blades, resulting the operation of fans even in the very aggressive environment. Lightweight FRP fans also ensure a low moment of inertia, minimum wear & stress on motor, bearing and drive system.

Hollow FRP blades reduce material & installation costs and possibility of damage to the fan & drive during sudden stops. Composite structural design can be tailor made by using glass fibres in various forms (woven mat & rovings) in right direction while moulding the impeller with resin thus imparting the desired mechanical strength by improving its structural stability and enhanced mechanical properties.

Aerofoil design of fan impellers ensures higher efficiency, lower noise levels & less power consumption. The aerodynamically designed impellers of fans, fabricated by composite material can be an excellent alternative to ensure enhanced efficiency & appropriate energy savings apart from a wide gamut of critical advantages.

The FRP fans offer certain critical advantages as mentioned hereunder:

– Optimal aerodynamic design of fan impellers to provide higher efficiency for any specific application.

– Reduction in overall weight of the fan, thereby extending the life of mechanical drive systems.

– Require lower drive motor rating and light duty bearing system.

– Low power consumption resulting in appreciable energy savings.

– FRP fans fabricated by compression moulding/resin transfer moulding technique would have uniform dimensions and consistent quality.

– Lower flow noise and mechanical noise levels compared to the conventional metallic fans.

– Longer life of fans due to improved mechanical strength.

The potential of FRP composite for various applications is very wide. In view of the crucial need for developing indigenous capability in composite technology the main advantage of FRP fans is their utilization and application of composite as an important performance material in various sectors and to improve upon the laboratory-industry linkages towards development & commercialisation.

Ventilator Fans – Methods of Building Ventilation

When straightforward breeze conditioning system is possible, the rate of air velocity method outlined above should be the basic method used. However, there may be rooms or areas within the building that will require special treatment. If so, one of the other methods, such as spot cooling or zone cooling, may be combined with the basic method to achieve the over-all objectives.

Air circulators

Air circulators may be effectively used to boost air velocity through large buildings that have a flow pattern difficult to control. Air circulators are also used to redirect air into occupied areas near floor level. Air circulators are also effectively used in locations where adequate exhaust and supply air fans may be lacking. Air circulation alone may provide heat relief and cooling comfort to individuals in the area. Northern Fan’s Type CABL fan is ideally suited to this application. For many installations, fans like this may be positioned 8′ to 10′ above the floor and at approximately 50′ intervals to obtain a continuously circulating column of air across a room or building. To broaden the column of air, fans should be located abreast of each other 15′ to 20′ apart. Fan locations and positions are easily adjusted to the requirements of the area.

Although an accurate, intelligent calculation of the required air volume for a breeze conditioning system has been made, there are practical limitations in most buildings that may seriously affect the final results. By giving these limitations proper consideration in the planning stage, the system can usually be modified to compensate for them. Some of the more common limitations are listed here.

Air Flow Restrictions due to interior partitions

It is obvious that interior partitions restrict and interrupt the flow of air through a structure. The effect of these partitions on the system must be analyzed and solutions found. In buildings with very high ceilings. the cross-sectional area factor may become unrealistic in calculating the required air volume. In most instances, inexpensive baffles can be installed across the building width to reduce the effective cross-section to an area 10′ or 12′ above floor level. Machinery, raw materials and finished goods that obstruct air circulation. These obstacles, like interior partitions, must be considered and methods worked out to overcome the problems they create to the proper circulation of air through the structure. Frequently, the location of heat-producing machinery will seriously interfere with the preferred pattern of air circulation. This situation can destroy the effectiveness of the system. An alternative plan to overcome the problem is essential.

Another limitation of the very high ceiling or roof is the difficulty of maintaining the air velocity near floor level. The baffle method just described is usually the best way to reconcentrate the air flow along the floor level where it will be effective in providing personnel comfort. In large buildings, baffles may be required at l00-foot intervals to keep air flow near the floor level.

Operations within the area frequently require wall openings or loading doors that will drastically interfere with the desired airflow pattern. In some cases, individuals may open windows that should remain closed to maintain effective air circulation. A remedy for each of these problems is required. For maximum efficiency and economy, a good layout will avoid the restricted intake opening. The type of exhaust equipment normally utilized is most economical and efficient if static pressure in the system is 1/8″ or less. To obtain this condition, air velocity through intake openings should not exceed 1,000 feet per minute, a lower figure is usually desirable.

Industrial Fans Uses and Applications

Fans have helped to create safer and more pleasant internal environments for hundreds of years. The invention of mechanical fans is found in the industrial revolution and the first commercially viable electric fans were made available to the US public early in the 1930’s.

Fan Manufacturing and Ventilation Solutions

Today the technology behind fan manufacturing and ventilation solutions have sky-rocketed to create fans for virtually every use from cooling devices in a server room; to ventilation in a manufacturing plant; to keeping a bathroom clear of damp air.

Generally speaking, fans and their accessories can be divided into 3 main usage categories: domestic use, industrial use and commercial use.

Industrial Fans will often have a very robust requirement and it is essential to involve experienced engineers with the installation of such ventilation. Other than just determining whether the fans will be required for air supply or for exhaust functions (i.e.: as an extractor fan) the engineer or installation technician will need to be keenly aware of both the working temperatures of the units as well as any thermal protection qualities of its associated housing or frame.

Some industrial fans will come with controllable speeds which can be very handy in a changeable internal environment, especially with regards to saving on ventilation costs at times when the air regulation needs of an area are reduced. Special features such as built in monitoring and systems integration come in handy when working in a potentially hazardous environment for example when chemicals or volatile substances are involved. Generally speaking, fire resistance and corrosion resistance are both ‘plus’ features for any industrial ventilation setup. Above the ‘plus’ one will need to consider the health and safety requirements of your region such as vibration or noise control and air quality regulations related to worker health.

Commercial Fans

Commercial Fans would not have as robust a requirement but the overall integration of fans into the building structure and management system is key to efficiency. Automatic ventilation in refrigeration units or in rooms that will typically contain many people at the same time will keep areas safe and comfortable. Operational areas such as server rooms (also known as data rooms) and elevators will need to provide adequate ventilation, usually in the form of extractor fans, to remove excess heat generated by the operating machinery which often runs continuously. Commercial ventilation also acts as a barrier to unwanted external influences such as insects, pollution and natural allergens.

Domestic Fans

Lastly domestic fans find their main purpose in providing less costly air quality solutions. There are two ways to cut costs with a domestic ventilation solution. You can invest in a ‘cheap and cheerful’ unit from the beginning resulting in a smaller initial cost or you can install a slightly more costly fan and ducting system with operational features that help you save on heating and ventilation costs in the long run. There are a wide variety of low energy extractor fans and ventilation units are now available for kitchens, washrooms and living rooms. In addition heat recovery units now help you to use the heat from stale air that is being extracted to warm-up fresh air that is being pulled in by your system.

***

Commercial Extractor Fans

Today there are a wide range of commercial extractor fans available on the market to cover just about every application imaginable; from large commercial applications, such as restaurant kitchen extractor systems, to quiet airflow systems that are virtually silent in operation.

While a commercial kitchen extraction system, commonly made in stainless steel can cost several thousand pounds to buy and install, a large vent-axia through wall extractor fan may be fine for a small hot food business such as a shop making toasted bacon sandwiches.

The new quiet airflow extraction systems are proving popular as they have a high airflow, yet can barely be heard running. This helps keep environmental noise down, and this is often important in an office workplace.

Commercial Inline Fans

Commercial in-line fans are available that sit above the ceiling, often some distance from the room they are actually extracting the air from. They are connected to vents in the ceiling by ducting, which then connects to the inline fan, and then expels the air through more ducting to a grill in an outside wall.

This type of fan has to be used in certain “classes” of environment by law, whereby no electrically powered unit can be placed within a certain distance of damp areas, such as shower rooms as an example.

When buying a commercial extractor fan, you will have to take more into consideration than when purchasing a domestic extractor fan. The reason for this is that whilst a domestic fan may be cheap to buy and install, and can be replaced at a low cost if it breaks, the same cannot be said of a commercial extraction system.

Large Commercial Extractor Fan Installations

Most large commercial extractor fan installations will cost several thousand to buy, and will need professional installation. So given the investment you may make in one, you need to be buying with a reputable supplier, as you may be installing it in an environment where you may have to stop work if the extractor fan system breaks down, such as in a commercial kitchen.

If this happens, you need to know that someone can come out and fix your extractor fan very fast, as if you have to close your kitchen down, you will be losing money until it is fixed. So you need to do some research about the company you are buying your fan from, and ensure that they can provide a fast call out, and that they carry sufficient spare parts.

Blower Fan Ventilator – Air Make Up Fans

Lack of make-up air in a building can cause serious problems. Many times the problems are not even recognized and show themselves in ways that most people do not think about. A properly designed and installed ventilation system provides environmental control by avoiding negative pressure. Uncontrolled infiltration of air through window sashes, doors and walls leads to many undesired results. In this article we will discuss a few of these problems and inform you about the cost of make-up air.

The signs that You need Make-up Air Fans include:

1) Poor paint finishing due to dust, moisture or fumes. Exhaust fans will compete with each other for the available air. They are going to pull air from anywhere they can. Paint booth fans may lose out in the competition causing the paint to retain moisture and collect dust that is not removed by the exhaust fans.

2) Walls have moisture being pulled through. This shows that your plant is under negative pressure. Cement walls have small cracks that allow water to penetrate. Fans pull from every place air can get through. This includes walls. When fans pull air through walls, water from rain and other outdoor sources will also be pulled through. This will cause firring strips to rot, ruin wall coverings and paint jobs.

3) Smoke, haze and dust floating in the air. As you look across the factory is it hazy? You should be able to see clearly from one end of your factory to the other without the view being blocked by haze and smoke. If the area clears when a window or door is opened, it is starved for air. This indicates that the exhaust fans are competing for air. Welding, molding, metal cutting or many other processes can generate fumes that need to be exhausted or the factory could become hazy.

4) Stacks and exhaust fans take up a large portion of your roof. If this is the case, you are a prime candidate for make-up air. The number of stacks and exhaust fans on the roof is an easy way to gauge the amount of makeup air needed. The area of inlet air should be equal to or greater than the area of exhaust air. The hoods seem to have a downdraft rather than the normal updraft. The fumes from hoods are supposed to go up the hoods, but if the fan is starved for air the fumes will be found in the plant. This is also true for gas hot water heaters, boilers, furnaces and unit heaters or any other process that has a flue on it.

5) Fan motors also work harder when they are required. When a fan attempts to move air that is not there, it causes the load to rise. This causes the insulation to break down and shorten life. Motors should last 7 or more years. When every exhaust fan in the plant is fighting for the same air, all the motors are going to have decreased life.

6) When walking through the plant, odors seem to linger. Weld fumes, paint fumes and dip tanks all need to be exhausted. These fumes can cause undesirable mixtures of odors that linger and cause burning, watery eyes, sore throats or sinus trouble. This contributes to an Locker room, bathroom and other odors seem to creep through the plant and office. People’s clothes smell like the production line. Processes like oil mist, boilers, roasting ovens and paint booths have odors. All these aromas require ventilation. If the ventilators cannot provide the required number of air changes in the room, your plant is short of air.

7) Doors that are hard to open or doors that will not shut on their own are a sure sign that the plant is short of air. Inward swinging doors are easy to open and hard to close. Drafts through the door seals and knobs that are hard to turn add to the problem. Outward swinging doors are hard to open and “slam” shut, damaging seals and wearing hinges. Hydraulic door closer settings are set high to pull doors closed without slamming.

8) Shutters on the exhaust fans are not 100% open. Automatic or balanced shutters are not open. These shutters should be 100% open when the exhaust fans are running. If the exhaust fan is not getting enough air, the shutter will not open all the way. The shutters should gradually close when the fan is turned off. They should not slam shut.

9) Steel near the fume hoods is corroding due to fumes that should be exhausted. Many corrosive liquids require their own hood. Typically the hood is a stainless steel and will not deteriorate from the fumes. If the air is not going up the hood and fumes are being pulled through another exhaust fan that is not designed to handle the corrosive atmosphere, the fan and any nearby steel will also corrode and decrease the life of the unprotected equipment.

10) Cracks under the doors collect leaves, dirt or gum wrappers. The threshold of the door will collect a substantial amount of debris during the day due to the exhaust fans trying to grab air from anywhere they can get it. Part of grabbing the air will be the collection dirt and trash.

11) Cold walls. The walls should not be cold. The wall can act as an insulator if the air is balanced. Insulation will prevent some drafts, but no insulation will prevent all the air from coming through. With negative pressure, however, the drafts through the wall will be cold regardless of the amount of insulation. These cold drafts will cause absenteeism and help spread colds and illness throughout the building. People will constantly fight over the thermostat setting. Fuel will be conserved with proper ventilation. Without make-up air, cold conditions near the building perimeter and overheated areas in the middle of the building lead to installation of more inefficient unit heaters. These heaters work overtime to heat the air, which in turn gets pulled to center of the building thus adding to the overheating problem.

12) Pilot lights go out and the area smells of flue gases. The flue gases from the unit heaters must go up. When makeup air is needed, these gases do not go up the flue but back into the building. Unit heaters are not necessary with the proper makeup air units. The heat for the plant will come from the makeup air unit and the unit heaters will not run.
