Why Hire a Ventilation Service Professional?

Ventilation in your office building is one of the most important aspects of an airtight and environmentally friendly facility. It can help to control the moisture level in the home and to provide energy efficiency, comfortable and healthy place to work. Many people don’t understand just how important it really is. Not only does it eliminate bacteria and disease, but it also allows the exchange of outdoor air with indoor air. Ventilation minimizes odors, moisture and indoor pollutants. Poor ventilation can lead to the growth of volatile organic compounds, radon and formaldehyde in your business. Even high levels of moisture can raise the humidity level leadings to mold growth and structural damage.

When ventilating your business, a professional company such as Corporate Mechanical can make sure that your building is accommodated at a rate of .35 air changes per hour. Proper ventilation should be able to accommodate the best quality of indoor air. The standard ventilation rate is 15 cubic feet per minute. As you can see, it’s important to hire a professional who is used to these calculations and can ensure the proper ventilation is used in your particular building.

It’s also critical that the company you hire for this service understands the basic functions of ventilation before a plan is devised. The ventilation system created should be able to draw in air from the outside, which can consist of less pollutants as well as water vapor. Corporate Mechanical offers a complete ventilation solution using the most updated equipment for your next project at your business. For a properly ventilated business, choose a professional company that is properly trained, experienced and insured. Serving Minnesota residents, they believe in providing a quality service experience to each of their customers time and time again.

Common Problems With Commercial Air Conditioners

There are several reasons that a commercial air conditioner may not function properly. These could include a faulty thermostat. A bad thermostat could cause the air conditioner to come on or shut off more often than it should. It could mean that the air conditioner is not doing the job as well as it should be and that it is ultimately costing more money to run. This is typically a simple fix but could cause a great deal of problems for the proper use of the unit.

Another possible and common issue relating to an air conditioner is if the unit is not properly ventilated. If there is too much around the air conditioner and it isn’t getting enough air, it could malfunction or overheat. Making sure the area is clear of all items that could stop the air conditioner from working properly is important. This also includes the indoor ventilation system that runs to and from the air conditioner. Vents that are not properly set up, that are blocked by items or that have filters that are full of debris can cause the unit to work poorly.

An air conditioner that has a great deal of debris, has not been oiled and cared for and has not been tuned up can stop working as efficiently. This can be easily remedied by having a professional such as those at Corporate Mechanical come in regularly to service the unit. This also gives us a chance to see if there is any potential problems headed your way with the unit and address them or repair your air conditioner unit before it gets out of hand.

If an air conditioning unit is working too hard to heat and/or cool a space, it can cause it to be less effective. This could happen if the space it is trying to move air in is too big. Making sure that you are using an air conditioner that is appropriate for the commercial space it is in will help it to work better.

The Benefits Of Hiring a Commercial HVAC Maintenance Company

If you own a business, you will certainly understand the importance of keeping it well maintained. Many businesses overlook their HVAC systems and this leads to problems later down the line. For example, you may not realize that your air conditioning isn’t working until a heat wave strikes the area. Your employees will overheat and they won’t work to their maximum ability. This can all have an impact on your business so it really helps to have an HVAC maintenance company on-hand if you want to keep your business operation at a high level of efficiency.

What an HVAC Maintenance Company Can Do For You

An HVAC maintenance company can work with you to make sure that your air conditioning, heating and ventilation systems are in full working order. They can also help you to fix any problems as soon as they arise, and this can help you to save money at a later date. You will also find that by hiring an HVAC professional you can make your systems last much longer and this is a great way to cut back on cost at the end of the year.

An HVAC company will also be able to tell you how energy efficient your systems are. For example, if your systems are not very energy efficient then you could be wasting money from the start of your business day to the moment it closes up for the night. Over the year, this can really add up but it is something that you might not even be aware of. An HVAC professional will be able to help you with all this as well as advising you accordingly so there are certainly many benefits when you hire one for your business.

8 Tips to Save Energy at the Office

It seem energy bills keep getting higher and higher in both the residential world and the commercial world. By switching to more energy-efficient practices, not only will your wallet benefit but also the environment. Take a look at some of these 8 tips to save energy at the office. Some of them are quick fix, change of habit take the tips, as others are going to take some research finding new energy efficient technologies.

8 Tips to Save Energy at the Office


Use Energy Efficient Appliances. Look for appliances that have the Energy Star label on them. This is a movement from the federal government that specially marks high-rated energy efficient appliances.

Do Not Use ‘Standby’ Technology. When leaving the office for the day, be sure that everything is turned completely off and not left on standby mode. Standby keeps the energy flowing into the equipment even when it’s not being used.

Install Window Coverings. The use of blinds or shutters on the windows will help minimize the heat of the sun directly beaming in during the summer. Allowing your AC unit to not have to work harder to keep the air cool. On the flip side, open the shades in the winter to allow the heat and the sunlight in.

Install Motion Sensor Lights. Using a motion sensor type of lighting system in the office can help eliminate energy use from people leaving lights on. This is most practical in break rooms, bathroom and anywhere that would be easy for a turned on light to go unnoticed.

Install Water-Saving Fixtures. Saving water is also another way to conserve energy. Installing water saving faucets can help improve the amount of water used. Also, the use of low-flush or even dual-flush toilets can help keep the water use to a minimum.

Set the Thermostat. Setting the hours and temperatures on your thermostat will help monitor the temperature in your office. While you are present, have the temperature set for what you desire but when you are absent, turn the thermostat down. This will help keep your electric bills down from your heater or AC unit.

Hire a Green Energy Company. There are many utility companies that generate electricity from wind and other green alternative sources. By switching to one of these companies your electric bill may decrease and you will also be helping the environment.

Use Laptops. Your average laptop versus a desktop computer will use less energy and can be more efficient. The idea is to buy the quality computer laptop over and less expensive one.

Taking note of your energy use in the office will help you to better assess the areas in which you can improve. By slowly changing some equipment and habits, you can start to lower the costs of your office energy bills month by month.

What To Know About Eddy Current Testing

Eddy current testing is a way for those who work with specialty metals to test for imperfections, such as cracks or gaps. These flaws are detected by electromagnetic induction. It can catch these flaws on the surface of the material, but also in the sub-surface. Not only that, but eddy current testing can also be used to measure the conductivity and thickness of a material. Here are some things that you might find interesting about eddy current testing.

Nondestructive Testing (NDT)

Eddy current testing is categorized as a nondestructive testing method. This means two things. For one, the system is reliable, safe, and cost-efficient. The other is that the testing is conducted without causing harm to the material or any parts connected to it. It will also do nothing to affect the use of them in the future. There are several NDT techniques, including simply using the eyeball test, and eddy current testing is one of the most important.

It is Vital in Everyday Life

It may surprise you to hear that eddy current testing is an important part of our lives, but it is absolutely true. Eddy current testing is used in many industries and for many of the products we interact with daily. As an example, eddy current testing is the preferred method to use for testing oil and gas pipelines, chemical manufacturing, nuclear reactors, and our local water systems. There is portable equipment for eddy current testing to perform inspections on site, such as on bridges. Public safety is greatly enhanced by using eddy current testing, which makes it important to us. Not only can it be used for those large components, but it can also be used for smaller parts that also have an impact on safety.

Different Probes Depending on the Mode

ECT uses test probes that come in several styles and sizes. They do not just have different shapes, but also have varying modes of operation. Take, for example, an absolute measurement probe. This probe creates eddy currents by using a coil. These currents then track any changes in the current field. Another probe has two coils, so that the operator can use comparisons to find flaws. If there is a coil lingering over an imperfection, and the other is over a good spot, then the operator gets a signal.

There are Several Factors That Can Affect Eddy Current Testing

Eddy current testing equipment generally comes with several settings. There is amplitude, frequency, and sensitivity, among others. These all need to be considered when performing ECT. That said, there are other factors in play as well. You must consider anything that might affect the flow of the currents, such as any properties of the material you are testing. If there are obstructions, then an adjustment to the settings may be required.

Magnetic permeability is one of those factors that can affect how easily the currents flow through a material. When measuring permeability, there can be interference created when using ferrous materials. That makes it hard to use eddy current testing for accurate results. To get over this, technicians can use magnetic saturation or different coil arrangements to get accurate readings.

When it comes to interference, even ambient room noise can cause problems for eddy current testing. The best option is to try to filter out any noise in the environment to get a good signal. There can also be issues if the part or material being tested has sharp or geometrical edges. Technicians can use a special scanning technique to overcome this.

The eddy current testing procedure is used on several materials, such as tungsten and molybdenum rods. It is an effective way to inspect materials for damage, cracking, fractures, and pitting.

A Guide to Pneumatic Control Systems

You may have heard of pneumatics before, but may not really know what it means. At its most basic, pneumatics involves using pressurized air or gas. A pneumatic control system helps to control an HVAC system by using compressed air. Here is how a pneumatic control system works.

Process

The compressed air used by a pneumatic control system is pushed through plastic and copper tubes. It starts from a controller, and travels to a controlling device, which is most often a damper or a valve actuator. There are sensors attached to the lines that measure any changes in temperature, humidity, static pressure, and other factors. In effect, the compressed air is the method by which all of this data is communicated. A thermostat will be connected to these lines and will regulate the air accordingly.

Actuators

Pneumatic actuators are the motors that drive the whole system. They control the valves and dampers. They are extremely durable and reliable, and are very cost-effective. There is no need for regular maintenance on these actuator types, either. In just about every factor, whether it be durability or affordability, these actuators are superior to electric actuators.

Modular Control Components

The components that make up the system provide excellent performance and versatility. These components, such as receivers, thermostats, and pneumatic relays, can be custom configured to fit your building’s needs. No matter what, they will relay the necessary data accurately regardless of how the system is configured.

Limitations

Despite it being an uncomplicated system, there are some limitations to pneumatic controls. Because of its simplicity, building managers often overlook or forget the need for quality preventative maintenance. It is not a process that can be handled by just anyone. The air supply should be checked regularly to make sure that it is clean and dry. Also, a regular maintenance program is required to inspect all components of the system. Every two years or so, components should be adjusted to make sure there is no shifting of the setpoint.

Maintenance and adjusting are best handled by professional contractors who know the ins and outs of pneumatic controls. They will make sure that your system is running smoothly and efficiently at all times.
