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.

HVAC with Industrial Blowers and Fans

Heating, Ventilation and Air Conditioning (HVAC) is a system that provides warm air or cool air depending on your climate needs. HVAC systems are esteemed for their energy-saving abilities. They are installed by certified HVAC trained technicians only. Because of its awesome benefits, along with its pollution control feature, more homes are being installed with HVAC Indianapolis systems each year.

Another benefit of having an HVAC system installed at your home is its ability to clean and improve the air’s quality. Studies show that the quality of indoor air is way worse than outdoor air because indoor air is congested. The polluted indoor air, in turn, worsens allergies and causes colds to stay longer. With an HVAC system, the air indoors will constantly be exchanged with filtered fresh outdoor air.

It is true that the initial cost of an HVAC system is quite high. In fact, it is higher than the typical gas furnace. However, in the long run, each month you will feel the difference through your energy costs. Also, with HVAC systems, you won’t have to buy separate systems for heating and cooling and since there is only one machine, home space will also be saved for other important things. In addition, some HVAC systems run on renewable energy via solar panels. Plus, a non-chlorine-based coolant is used. You are actually saving the Earth too!

One major problem of most homeowners is moisture retention. Whether your local climate changes every few months or stays constant, moisture stays in your home. Indoors, air does not circulate properly without decent ventilation. Because of this, outside air cannot be able to circulate with the indoor air. When this happens, molds are more likely to grow inside walls, under floors, and even on your clothes. To avoid this, you need to dehumidify your home. An HVAC Indianapolis homes use can help you circulate indoor and outdoor air for less moisture in your home.

Moreover, HVAC systems increase a property’s value. In the case that you decide to sell your home in the future, your HVAC system will aid in appraising your home’s value. Compared to having an old-fashioned gas furnace which can be a potential fire hazard, an HVAC system is more convenient, appealing, and, not to mention, safe. Surely, most potential buyers will choose HVAC systems over old gas furnaces.

Consult your local heating and cooling Indianapolis based company about the things you need to prepare and are concerned about when planning to buy an HVAC system.

How to Improve Air Flow Ventilation

Improvement the air circulation in the building makes a huge difference because the faster the air moves through your home, the easier it is to maintain a temperature within your home. The heating, air conditioning, plumbing, and electrical service shops can help you to choose the different methods which will make this possible. The good news is that most of these methods will allow you to not only have more consistent temperatures throughout your home. They will also help you to be able to spend less money to get the results you are looking for.

There are three methods you can try for improving the circulation in your home. One of the ways is to make sure that you are getting the right amount of air flow through the ventilation system in your home. You can also make sure that you are regularly changing the air filters. You can also make sure to use electric zoning so that you will be able to get constant temperatures throughout your home. The more you are willing to invest in the different methods for circulating the air throughout your home, the more comfortable your home will be.

Improving Air Flow in the Ventilation System

There are many different ways in which you can improve the amount of circulation that you get. One way is to install duct fans. These are blowers which will help to force the air through the ventilation system and into the different rooms of the home. These are especially useful when you notice that certain rooms of the home are harder to ventilate or affect the temperature than others. They work remotely, but in conjunction with the HVAC unit so that they will only operate while the system is on.

Change Your Air Filters

Improving indoor air quality is possible by making sure to change the air filters regularly. Not only does changing the air filters help to improve health by improving indoor air quality. It also helps to make sure that the air is able to flow easily throughout the house. This will help to make sure that you are getting the right kind of ventilation so that the entire home will be as comfortable as possible. Try to invest in air filters which will filter out different kinds of allergens.

Maximizing Temperatures through Electronic Zoning

When you have better ventilation, you might also want to invest in electronic zoning. This is when you use different thermostats throughout the home to control the temperature in different zones. The greater control will allow you to be able to make sure that the right amount of hot or cold air is getting to where it needs to be. You will no longer have to rely on one thermostat to control the temperature for the entire home. This will improve circulation greatly.

Industrial Propeller Fans and Industrial Blowers

Electrical generators require the most reliable equipment for their air-cooling and ventilation needs. The fans used in these systems are mounted onto gas-turbine generator packages for use in power plants as well as on cruise ships, oil rig platforms, and mobile generators. These systems are loaded onto tractor-trailer rigs or barges and moved to a site to generate power for events like the Super Bowl and concerts. Manufacturers of these gas-turbine generators are realizing it pays to have the right fan for the job from the start and are turning to Buffalo Fan to provide these unique solutions.

Resilient Industrial Blowers

A key requirement for these applications is that the fans need to be exceptionally corrosion resistant to withstand these severe environmental factors.

Noise attenuation is a major issue for power generators, both to protect workers’ hearing and to keep operation at the quietest level for any surrounding residential or business communities.

High Performance Fans & Blowers

Power generation is a complex process. The power generation fan / blower equipment should be tough enough to avoid operational failure and to minimize installation and repair work. The rugged, high performance fans Buffalo Fan provided to a state-of-the-art hybrid energy center, were ideal for the task. Aerovent was chosen for this project because of their reputation for building large custom fans for extreme industrial applications. The energy center’s primary requirement was that its chosen vendor be able to design and build a set of the most rugged, efficient roof ventilators within budget. Most roof ventilator fans last between 10 and 20 years when properly maintained. Because of the permits and cost involved in performing maintenance work on the roof of a power plant, they wanted their fans to have a longer life span (up to 40 years). This lifespan requirement meant that the fans had to be constructed using industrial grade materials and components.

Propeller Fans

Northern Fan propellers provide equal airflow in both directions. Other companies’ fans have a standard-exhaust one-direction propeller and are run backwards for the supply mode, producing about 40 percent of exhaust-mode airflow. ABuffalo Fan blowers produce 100 percent airflow in either direction. Aerovent also produced an integrated electrical control system guaranteed to work with its fans instead of the power plant having to acquire a separate system from another source. The system features an onboard starterdisconnect switch, which boosts the motor’s start and can be easily disconnected.

Industrial Blower Safety

Fire safety is a challenge in any environment, and especially so in a power plant. In case of a fire, the first priority is to ensure the safety of employees. Another goal is to be able to salvage expensive equipment in the building. With ventilation fans, if the motor fails during a fire, it is more beneficial if the fan’s dampers automatically fail in the “open” position, and allow smoke to escape.

Custom Industrial Fan Design

Northern Fan’s expertise in custom-building fans for complex applications, like this energy center, allowed them to design and construct a special fire damper for the fans. When the motorized damper is activated, a metal linkage arm attached to the damper blades moves to open or close the damper.

Northern Fan Co. custom made damper features a fusible linkage arm with a “soft metal” section in the link. When temperatures reach 212 degrees (as in the case of a fire), the soft metal plate fails, breaking the linkage, and a heavy counter weight swings the damper into the “open” position.

High Temperature Blowers

Northern Industrial Co. offers new temperature blowers and fans for various industrial applications to 2200 F. This was achived by using extremely high strength stainless steel alloys for the fans impellers, that allow for higher safe speeds at elevated temperatures.

The Northern Industrial high temperature oven fans line now include:

Operating up to 2200 F, centrifugal, axial and plug fan types;
Pre-engineered and custom made fans for all types of applications with variety of impeller types and accessories;
Canada Blower engineers provide a professional advice and recommend a right fan for every application & oven / plenum design;
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 Fan Ventilation Importance

VOCs, or volatile organic compounds are emitted by a wide array of products and processes. Paints, lacquers, cleaning compounds, printing, and a host of other substances found in industrial environments release pollutants into the air that have adverse long and short term health effects. VOC pollution is especially hazardous in the high concentrations found indoors.

Industrial Blowers Fans Applications

Northern Fan Co. custom engineers effective process gas exhaust systems for industrial applications, considering factors such as:

VOC loading of the gas stream;
Regulatory requirements;
Solvent recovery needs;
Lifecycle costs.

Industrial Fans and Blowers Features

Ability to treat nitrogen containing organic compounds without the formation of NOx,
VOC control while consuming less energy due to lower operation temperatures.

Industrial Pressure Blower Safety

Due to NFPA standards and a growing awareness of workplace health and safety hazards, industry has seen an increasing demand for effective explosion protection systems. The flammable gases and combustible dust resulting from many industrial and manufacturing processes create a serious threat, which necessitates dependable explosion prevention. Protection is also needed for potentially explosive environments that include functions such as:

Conveying – Elevators, Pneumatic Ducts, Separators, Vapor Control;
Processing – Coaters, Cookers, Dust Collectors, Dryers, Paint Booths, Sanders;
Pulverizing – Ball Mills, Cage Mills, Flakers, Granulators, Grinders, Shredders;
Storage – Bins, Cyclones, Flammable Liquid Storage Areas, Hoppers, Tanks.

Many explosion prevention measures will comprise an explosion protection system, as well as measures to contain or mitigate potential explosions.

Industrial Blowers and Fans Ventilation

To obtain a reasonable degree of personnel comfort in hot weather, there are three basic factors that should be provided for in the ventilation and cooling system of a commercial or industrial building. The first step toward controlling the hot air problem is to provide for the removal of excessively hot air from the building. This superheated air frequently mixes with the air in the cooler areas of the building to produce an overall temperature increase. As superheated air is frequently localized around heat-producing machinery, it should be exhausted from the building near its source.

Inline Centrifugal Exhaust Fans & Blowers

Industrial Blowers and Fans — About Air Handing Fans

Since July 1, 2003, equipment manufactured for operation in potentially explosive environments has been required to comply with the European Directive 94/9/EC. This directive, commonly referred to as the ATEX Directive, applies to all countries in the European Union (EU) and the European Economic Area (EEA). The ATEX Directive is a collection of EU directives outlining equipment installed and operated in potentially explosive atmospheres. The ATEX directive coordinates various technical and legal conditions throughout Europe to ensure a high level of safety for the end-user by reducing the explosion risk through established design methods. The European Committee for Standardization (CEN) published EN 14986 as a standard specifically for the manufacture of fans for use in hazardous areas. This standard is a guide specifically for fan manufacturers to comply with the ATEX Directive.

Industrial Blowers & Fans – Air Handling Units

Air Handling Units (AHU) combine a fan (or several fans) with other components such as heating and/or cooling elements, filters, and dampers as a means to collectively condition the air in a building. AHU is a general term comprised of many specific types of air handlers including: Make-Up Air Units (MAU), Packaged Units (PU), Rooftop Units (RTU), and Energy Recovery Units (ERU). Air handlers range from very small, low CFM light-duty construction to very large, high CFM heavy-duty construction, and are used in many types of buildings that require air conditioning such as office buildings, hospitals, universities, schools, manufacturing facilities, and data centers. Typically, air passing through an AHU is clean and varies in temperature depending on the specific application. Energy consumption and noise are often important considerations when selecting a fan for an AHU. Plenum fans and DWDI fans are commonly found in these units, but are not used exclusively. To accommodate the various applications these units are used for, Canada Blower offers the most diverse and efficient fans in the industry to meet the need of any air handling unit.

Building elevator shafts require proper air moving equipment to provide smoke control in the event of a fire. Pressurization is used to prevent smoke from migrating through elevator shafts to other floors, similar to how fans are used to control smoke in stairwells. Today’s elevator pressurization systems are designed to allow elevators to be used by firefighting teams. However, some systems are designed for the evacuation of handicapped individuals. While small amounts of smoke in an elevator may be tolerated by firefighters, smoke in an elevator and its entry and exit paths is unacceptable. Canada Blower’s complete offering of smoke and heat exhaust fans are relied upon for elevator shaft exhaust/pressurization in emergency situations.

Electrical bus systems are used for conveying large volumes of energy within power generation facilities. The efficiency of an electrical bus is a function of temperature. The cooler you are able to keep the bus the more efficient it will operate. Power plants utilize large electrical buses and Buffalo Blower provides fans for cooling these systems. Typically this involves clean air which is circulated through a closed loop system.

Air supply and filter houses provide the clean supply air for large scale paint booth applications. The supply air is conditioned and filtered to the precise temp and humidity for the given paint system. This supply air is sent to the main paint booths, curing ovens, electro polishing rooms and pre-treatment areas. Buffalo Blower offers a variety of efficient airfoil fans to meet the stringent requirements of any customer.

Emergency smoke exhaust systems are designed to remove smoke and heat from buildings in the event of a fire. These systems play a crucial role in increasing occupant safety and allowing rescue personnel to safely enter burning buildings. Canada Blower offers a full line of smoke and heat fans capable of withstanding a minimum temperature of 500°F for four hours or 1,000°F for 15 minutes. Our inline smoke and heat fans are also available in a vertical roof mount configuration featuring a discharge cap with butterfly dampers and an optional fusible link designed to stay open in the event of a fire.

Industrial Fans

Energy recovery systems have become a popular way to heat and cool homes as well as commercial buildings. Energy recovery applications typically use two fans that provide air through a heat exchanger that “treats” the air by heating or cooling it before it enters the building. Canada Blower’s plenum and forward curved fans are typically used for energy recovery applications and offer a wide range of performance and flexibility.

Inline Exhaust Centrifugal Fans

Generator rooms require a wide range of fans to optimize the performance of generators and other equipment. Exhaust fans are used to prevent heat buildup within the generator room, while supply fans are used to provide fresh air for combustion and efficient generator performance. Room size, space limitations, and mounting capabilities will determine the exact type of fan needed for each specific application. As a leading manufacturer of air moving equipment, Canada Blower offers numerous fan types for meeting any generator room specification.
