Industrial Air Curtains

The idea of having an invisible barrier across the doorway to enable unimpeded access yet effectively prevent temperature flow, dust, odours and insects to cross, is appealing in itself but add to this the cost-saving in reducing energy use and the idea becomes more compelling, especially as air curtains are relatively inexpensive items.

Appropriate for industrial applications

Keeping warm air out of insulated cold stores or refrigerated facilities is the Number 1 objective yet a mockery is made of this premise when freezer of chiller doors are left wide open and, in some cases, chocked open to facilitate the movement or storage of perishables.

Self-generated pressure evolves from a non-circulatory type of air curtain as the jet induces ambient air into the stream. When the air curtain is installed on the outside of a cold room, the air spills back into the room and continues to do so until the pressure builds up to such a point that the air stream deflects to the outside.

Pressure Form Stack

The pressure-form-stack effect evolves when the cold air in the room is denser than the warmer outside air. The higher the ceiling, the higher the pressure becomes inside the cold room. The velocity of the air curtain should therefore be high enough to compensate for the outward pressure at the lower part of the cold room.

Wind pressures occur because of the conversion of the velocity pressure in the wind into static pressure. Of particular significance is the stability of the air curtain, which is directed by its outlet momentum. The curtain of air must be able to withstand pressure variations between the inside and the outside of the cold room. The outlet momentum should be sufficiently sustained and strong enough to stabilise the air at the floor. It is therefore essential to incorporate controls in the design of the air curtain to increase the strength of the velocity and ensure a stiff curtain of air and to decrease the velocity to prevent unnecessary heat and moisture transfer at the door.

Refrigeration Applications

In refrigeration applications, a high volume of turbulent air hitting the floor tens to form ice on the floor of freezers – this is not desirable or necessary so air flow needs to be adjusted so that it barely hits the floor. This can be accomplished by adjusting air louvers or fan speed to obtain the desired velocity. Drafts are eliminated by ensuring that air flow is vertical. The air curtain may be mounted on either the warm or cold side of the cooler with equal effectiveness.

The volume of air flow varies according to temperature difference between internal and external air and air exchange is therefore caused by thermal temperature differences. Using known values for the indoor and outdoor temperature difference, the densities, pressure differences and ultimately the air flow through the opening can be calculated.

Properly installed air curtains cut cold air loss and reduce humidity, thus reducing the load on refrigeration or air-conditioning plant and thereby saving energy by reducing compressor running time, maintenance, gas and recharging intervals. These units are an alternative to fast-acting roller doors and PVC slat curtains, and can be situated above or to the side of industrial doorways to create a powerful seal across the opening, keeping cold air in while providing complete visibility and access. This means that forklift drivers don’t have to get out of their cabs to open and close doors so that moving from one area to another is a lot easier and productive. Unlike plastic slat curtains, which quickly become opaque with use, an air curtain provides 100% visibility at all times. Units have been installed in loading bays, factories, hangars and production facilities, such as food processing and pharmaceuticals, where differential temperatures are encountered overseas.

Canadian Air Systems Co. is a well known designer and manufacturer of industrial and commercial air curatain systems and environmental air barriers.

For special applications Canadian Air Systems offer tangential air curtains to achieve high volume alminar air flow – to create permanent environmental air barriers.

Industrial Floor Fans

There are many industrial floor fans available on the market today. It may be difficult for you to chose from the various styles and colors available. The most common ones are black, metal or white. Some can go close to the floor and some are on stands. You need to be sure that you pick the type which fulfills your needs.

One thing to consider is the size of the area you want to cool. If it is a larger area then you may need to purchase a stand to put it on. If you have a smaller room then a small floor industrial fan is more appropriate. You must also consider safety and place the fan in a location where mishaps are unlikely to occur.

Industrial Fans Manufacturers

There are also many manufactures who produce industrial floor fans. This should also be selected with caution. Be sure you pick a manufacturer who is well known and has good feedback. If purchasing a fan made by an unknown or not so popular manufacturer, do some research to find out the type of support they provide. Make sure you check to see what is covered by warranties.

Choosing an Industrial Floor Fan

When picking out your industrial floor fan, make sure you see what can of noise is generated. This aspect will not make a difference if the fan is located in a garage or another area that is not used often. If the fan makes a lot of noise in a heavily used area, it can become an issue, especially in the workplace. It can take away concentration from work. Of course, the larger ones will be noisier only because of the size. Some make a lot of noise because of how they are designed. Others are designed to be quiet and do the job efficiently. Don’t only go by looks. Make sure you look at all of the product specifications.

Select a model that generates as little noise as possible. It won’t be possible to get one which is silent, but get one which won’t affect daily activities for your business.

Why are these industrial floor fans used?

One main reason for getting an industrial floor fan is energy efficiency. Typical air conditioning for a large area will run up bills. A fan is more economical and provides cooling. Another reason is to dry interior decoration such as carpets as well as floors. Dampness and flooding can be eliminated through the use of an industrial fan. This recovery method for water damange is very economical.

Industrial floor fans are useful because of the more economical approach for cooling and don’t require fuel to operate. They are helpful all year round and not just in higher temperatures. Fans help to allow air to circulate evenly since heat rises. You can find an industrial floor fan either online or offline. If you are researching for a new fan, then looking online will be your best bet.

Proper Operation of Axial & Centrifugal Blowers and Fans

Proper Operation of Axial Blowers and Fans

In axial flow fan the air must blow in line with the axis of rotation and there must be blades with space between them. With few exceptions, the axial blower or fan must not have a lot of back pressure and will work a lot better if the blade is shrouded. One obvious exception is the turbine compressor used in jet engines, but this requires very tight fittings and very high speed so the air is being rammed in against the outgoing air much faster than it can move – it uses a lot of power and makes a lot of noise. Shrouding works better because the greatest loss in an unshrouded fan is the air coming off near the tips and immediately turning out and back circulating only through the fan and not through the room. The most common shrouded fan people see is muffin style fan in computers. An axial blower can have multiple sets of blades and the blades can even over lap so light is not visible through the fan. Fans are used most often for moving large quantities of air between spaces at atmospheric pressure.

Centrifugal Blowers

Centrifugal blowers come in a number of forms of which the most common is the squirrel cage blower. The common factor is the air is moving perpendicular to the axis of the part that is moving the air. Typically, the air is drawn in through the side of the unit, turns at low speed to encounter the inside of a spinning cylinder with ribs or vanes around the wall of the cylinder which fling the air out and away where it is captured and aimed through an outlet much smaller than the inlet. Think of taking an open tin can, drilling a hole in the center of the bottom to take a bolt as an axle and cutting slots up the sides, bending the material of the slots in, then spinning it with a drill. A variation looks like a plate with ribs running from the center and increasing in height toward the rim, the air being thrown off the rim. The name squirrel cage comes from the appearance like the tread wheel small rodents use for exercise – I suspect it is not called a hamster tread wheel because that is too precise – or childish. Blowers can have higher output pressures, but not a lot higher and they lose capacity rapidly with increasing pressure.

Common Blower Uses

Aside from the small squirrel cage blowers used on some electrical equipment, the most common blowers of this type are the units used for drying carpet after cleaning or a fire, the blowers used for leaf sweeping and the unit hidden inside a vacuum cleaner.

Industrial Blower Installation

Caution is necessary in selecting blowers for series installation. It is generally accepted that most pre-engineered blowers are capable of withstanding twice their catalog rated static pressure. In other words, where two blowers are installed in series the second blower housing should withstand the higher pressure. There is, however, a need for concern when the combined pressure exceeds twice the rated static pressure for one blower. In series applications involving three or more blowers, or in any system in which positive or negative pressure exists prior to the consideration of the blowers, special housing reinforcement may be necessary.

The fan offering provides competitive replacement fans to Garden City, Lau, IGE, Alloy Fabricating fan models; repairs, re-build & balancing;
Unique high temperature water-cooled motors for operation up to 2300 F.

High Temperature Blowers & Fans

Fans with ambient air cooling systems handling hot airstreams must have sufficient airflow and be kept in operation until airstream temperatures cool below 120 F to prevent damage to the fan unit. The Tubeaxial fan ambient air cooling system is only effective while fan is operating.

There are two major types of high temperature fans – centrifugal and axial:

Centrifugal Wheels:

Multiblade forward curve wheel. This type of wheel is usually specified where there is a necessity for large volumes of flow against low to medium static pressure requirements. The forward curve blade is that it delivers the same volume of air as either the backward or radial blade wheel, at a lower fan speed, which is important due to wheel stresses at elevated temperatures. This fan is the most common type used in all types of heat treatment operations except where a buildup of material on the blades could occur, as wheel unbalance would result.
Radial Blade, paddle wheel type fans. This type of wheel is usually specified where there is a necessity for medium volumes of flow against medium to large static pressures. The paddle wheel is considered a self cleaning type of wheel. It could be used where there are various materials or dust in the air stream. Due to its structurally strong design, it is used in many heat treatment applications at very high temperatures where maximum fan longevity is desired.

Axial Blade Wheels:

The axial blade wheel is usually specified where there is a need for very large volumes of flows against low static pressure. Axial wheel like the multi-blade forward curve type wheel could cause an axial fan to deliver different air volumes at the same static pressure, if the total pressure requirement of the fan system was underestimated. This type of fan is ideally suited where a large volume of flow is required with a minimum of duct work and is used extensively for small and large furnaces, such as aluminum annealing.

Fans handling hot airstreams must have sufficient airflow and be kept in operation until airstream temperatures cool below 120 F to prevent damage to the fan unit. The Tubeaxial fan ambient air cooling system is only effective while fan is operating.

Industrial Fans and Blowers vs Commercial Fans & Blowers

There is a difference between industrial and commercial grade fans construction. Industrial equipment is specifically designed and built to stand up to the rigors of an industrial application. The differences are concrete and easy to spot…if you know what to look for. Canada Blower designs and builds equipment strictly for industrial applications and has been doing it that way for over 100 years. Industrial fans and blowers are constructed of heavier duty materials and with higher quality components than their commercial counterparts. When properly applied, industrial equipment can withstand vibration, high and low temperatures, fumes and corrosive gases, materials in the airstream, and many other situations in an industrial environment. The equipment is built to provide longer service life, thus decreasing the need and frequency for replacements. Because industrial fans are expected to last longer, they are designed to be easy to install and maintain.

Industrial Blower Fan Features vs Commercial Blowers Fans

The best way to see the difference between an industrial product and a commercial product is to compare them feature for feature, including product weights. In the below example we’ll look at commercial panel fans versus Canada Blower industrial panel fans. The commercial grade panel fan has sheet metal, riveted blades, and a riveted hub. Canada Blower industrial panel fans have a solid, one-piece cast aluminum airfoil propeller or a cast aluminum adjustable pitch propeller. Lighter fans sometimes have balance weights clipped, bolted, or welded to the back of the fan blades, which can fly off during operation. Canada Blower cast aluminum propellers are precision ground and balanced, and therefore require no balance weights.

Industrial Fan Aerodynamic Design

Another difference between the commercial and industrial fan is in the aerodynamic design. Canada Blower originally developed the air seal venturi to improve performance. With this design, the propeller is larger in diameter than the venturi opening, thus creating an air seal. This design eliminates back flow of air pressure and increases air delivery by 10% or more. The way most other panel fans are designed, the propeller is smaller than the venturi opening. This type of fan is easier to manufacture, but significantly less efficient. The basket fan provides even less value because of the air that is lost around the sides of the fan. A Canada Blower venturi design fan pushes the air velocity from the blades out the front of the fan for increased spread and throw versus a commercial type fan.

Industrial Fans for Shipment

There are also installation differences to consider when purchasing a panel fan. Many commercial fans are shipped in parts. The motor and accessories may be shipped loose and must be assembled to the fan when received. In addition the commercial fan shown on the previous page has no provision for panel mounting or for accessory mounting. This means holes for bolts and mounting hardware must be drilled even before it can be completely assembled or installed. Canada Blower panel fans are shipped completely assembled and ready to install. A large selection of industrial fans are available from the stock program for quick shipment, including panel fan ventilators. You can be sure that Canada Blower equipment will provide many years of continuous service in your industrial air moving environment !

Industrial Blower Fan Ventilation

Aeration involves moving air through either a solid or fluid medium bed and is used for various purposes. Depending on specific material being aerated, our fans are utilized for moisture control in applications such as grain bin storage, and also provide oxygen and control moisture/temperature in composting applications. Due to varying environmental conditions, fans used in aeration systems often require special construction such as fiberglass, alloys and specialty coatings.

Industrial Fans for Ventilation

The treatment of wastewater can result in a variety of unwanted and hazardous gases, such as H2S and SO2. As the application specialists, Northern Fan has the expertise needed to supply the proper air moving equipment that is specifically designed for resisting the corrosive nature of these compounds. In other pollution control systems, our fans are installed on the clean side, which offer a higher efficiency design for moving gases into a scrubber or other device. One of the major challenges in wastewater and sewage treatment plants is controlling the odors that are emitted. These plants are often located in residential areas and forced to adhere to strict codes and regulations. These odors are caused by gases such as hydrogen sulfide and ammonia. To reduce odor emissions a variety of systems have been found effective, such as thermal oxidation, chemical scrubbers and biofilters. The fan requirements in these processes are similar in that they require special alloys, coatings or fiberglass construction.

Proper Industrial Blowers & Fans

Through decomposition, landfills produce syngas, a combination of methane carbon monoxide, and other hazardous gases. To avoid dangerously high levels of these gases, forced draft fans are used to drive fresh air into the landfill mass. Induced draft fans are also used for pulling noxious gases out of the landfill for safe disposal or for collecting them as a fuel source. The fans used in these applications often require special materials or coatings along with spark resistant construction. Depending on your specific needs, Northern Industrial Supply Company Fans & Blowers will work with you to select the proper air moving equipment.

High Volume Industrial Blowers and Fans

High volume, low concentration or non-condensable gases refers to gases that are in concentrations below their explosion limit. These gases are drawn through an induced draft fan and then processed with a RTO (regenerative thermal oxidizer) or incinerator that ultimately burns the gases for safe disposal. HVLC gases are often corrosive and at elevated temperatures, that is why we provide a number of fans that are corrosion resistant. In addition, we offer leak-tight construction to avoid emitting these toxic, flammable gases into the environment. In the case that these gases are above their explosion limit, Buffalo Blower supplies a full line of non-sparking fans that allow for the safe movement of hazardous gases. Based on your specific requirements, our fans can be constructed with aluminum and monel materials.

Large Industrial Ventilation Fans

In a manufacturing environment, vacuum systems are used to move and transport waste material. Sawdust, metal shavings, and other waste is easily transported away from work areas to a specified collection point for simplified clean up and removal. Vacuum systems are also used to provide suction for the manipulation of components, various materials and forming processes. These systems usually consist of long runs of relatively small diameter pipe or ducting. This results in the need for high pressure low flow fans.

Boiler Application Industrial Blower Fans

Boilers are used in a variety of industries for producing heat and energy. Many boiler applications will burn fuel readily available on site, such a byproduct from the given process. An example of this is Bagasse, which is a fibrous matter that remains after sugarcane is processed to extract their juices. The bagasse is a biofuel used for many boiler applications. Fans in boiler applications are forced draft, induced draft, over fire air and combustion air.

Large Industrial Fan Characteristics

At this juncture it is prudent to reiterate that a fan running at a particular speed can have an infinite number of operating points all along its characteristic curve. The fan will interact with the system to produce an operating point at the intersection of the system curve and the fan curve. Note that it is the system in which the fan is installed that will determine the operating point on the fan curve. Thus it is vitally important that the system designer accurately determine the system losses in order to ensure that the actual air flow rate is as close as possible to the design air flow rate.

Industrial Fans and Blowers

Industrial Fans & Blowers

Industrial electric fans clearly do not use as much electricity as an air conditioner, circulating air and cooling it at a fast rate for a large space. With high-powered, energy-efficient motors, the larger motor of an industrial fan is actually guaranteed to save energy costs.

Industrial Pressure Fan

Air conditioning can often become too large of an expense for industrial areas, but the good news is that an industrial fan can bring some much needed relief in this case. Industrial electric fans can be quite helpful for places where heat stratification, dampness, and stagnant air become frequent problems. Also, for high static pressure an industrial fan is what you need. Also known as an industrial electric blower, these units replace air as well by blowing out the old and stagnant air for a wide area that otherwise would collect this air without replenishing it in entirety.

Large Industrial Fans

Industrial warehouses, especially profit from these large units because the fans can support a higher CFM rating without the vibrations of a smaller fan. Most electric industrial fans have blades of a higher more durable construction, usually consisting of some kind of metal. This allows the blades to move more air at one time without all the force being applied to the fan and making the motor work harder.

Industrial Fan Types

Industrial fans include several types such as duct fans, roof and ceiling ventilators, wall mounted fans, pressure blowers, and freestanding units with different mounting options. For extreme conditions and plants, drum fans can be used to move even larger amounts of air. These types of fans come with wheels attached and can be rolled to the area that circulation is needed the most. Some manufacturers even sell just the fan heads for a more freedom and a reduced assembly and cost on the company.

Industrial Fan Motors

Powerful motors for reducing excessive noise are used in industrial fans. The motor will not be working at its top speed to produce the necessary airflow, therefore it will be quieter. Industrial electric fans are also very versatile; there are floor fans, wall mounted fans, and pedestal fans that all come in industrial grades. If you plan on a very large space, a pivoting fan is a good choice as you can manipulate the direction of the air and direct it to where it is needed most. Some even come with stands to make these larger fans easy to roll from place to place.

Electric Industrial Fans

These motors are designed to change a large amount of electrical energy into useful fan work. Often as electric industrial fans are in operation for an entire day period, opposed to a home fan which is turned on only when people are home, or in a specific room, the industrial fan needs to be energy efficient for this extra use. These motors can handle more heat than a normal motor meaning less heat waste is produced. If you think you need an industrial fan for your business area, chances are that you do! Make the choice today for comfort and health and consider an industrial fan purchase.

Centrifugal Industrial Blowers and Centrifugal Fans

Centrifugal Industrial Fans and Blowers

The majority of industrial centrifugal fans and blowers can be grouped into three broad categories; custom engineered, pre-engineered and OEM. All are supplied to the same exacting standards.

Centrifugal blowers and fans

Canada centrifugal blowers and fans are found throughout the world operating in industrial processes where performance, reliability and maintainability are of paramount importance. Ranging in diameter from 12″ to over 96″, and with a variety of impeller designs, control systems and layout options, they form a comprehensive series of centrifugal fans to satisfy virtually all industrial applications.

Industrial Centrifugal Fans

Canada Blower pre-engineered centrifugal fans are selected aerodynamically from a range of standard sizes and configured mechanically to meet the customer’s requirements. This allows to provide a cost-effective solution to moving air or gas where the additional cost of a custom engineered fan is not justified either by higher efficiency or mechanical strength. Centrifugal fans store significant amounts of energy when running, and if the fan is not correctly matched with the operating conditions the consequences for the plant operator can include excessive power consumption, noise generation or mechanical failure, resulting in a significant loss of revenue.

Industrial Centrifugal Blowers

Each of Canada blower designs has been exhaustively tested, aerodynamically and acoustically. The mechanical design is supported by modern analysis techniques, such as finite element analysis. Many options are available in terms of drive arrangement, output control, layout and auxilliary equipment, to give flexibility to the plant designer. All major impeller configurations are supplied including aerofoil, backward curved, backward inclined and radial tipped blade designs.

Centrifugal Fans

Canada Blower custom engineered centrifugal fans are designed specifically for each contract which allows us to apply a combination of experience, advanced design techniques and a knowledge of the operating conditions to select the optimum fan in terms of capital cost, running cost, maintainability and reliability. Large centrifugal fan rotors store significant amounts of energy when running. If the fan is not designed and manufactured correctly, and matched with the operating conditions, the consequences for the plant operator can include excessive power consumption, noise generation, vibration and mechanical failure, resulting in a significant loss of revenue.

Centrifugal Blowers

Each of centrifugal blower or fan designs has been exhaustively tested, aerodynamically and acoustically. Empirical design formulae that have been validated over many years are backed up with modern analysis techniques, including finite element analysis, dynamic response analysis and computational fluid dynamics.

Heavy-duty Centrifugal Blowers & Fans for Industrial Applications

It is this combination of knowledge and experience that has resulted in Canada Blower becoming a global market leader in heavy-duty centrifugal blowers and fans.

Centrifugal Blower Design

A centrifugal blower is a fan designed to move air or gases in a confined area. The centrifugal blower has a number of blades mounted around the hub, which turns on a shaft that passes through the housing. The gas enters the side of the fan wheel and by use of centrifugal force(hence the name) accelerates over the fan blades. A centrifugal blower is usually used in factories or large open places that need air flow.
