Nitrogen Generators

Nitrogen Generators

Nitrogen Generators. In many applications, oxygen is the enemy. Oxygen can cause food to spoil, rubber to deteriorate and steel to rust. The best way to combat the negative effects of oxygen is to supplant it with nitrogen. After all, the air around you is 78% nitrogen. For many years, the only option was to purchase bottled nitrogen. With the introduction of on-site nitrogen generators, users were able to cut the cord and move away from billion-dollar bottled nitrogen suppliers. This will typically lead to a huge financial savings that often results in an ROI of 18 months or less.

The overwhelming main benefit of an on-site nitrogen generator is the financial savings. Those savings can be experienced as soon as the nitrogen generator is in place.

Dealing with the Reduced Demand of COVID-19

We contacted hundreds of customers many of which are experiencing the same pain points. Those who have stayed open during these uncertain times are experiencing reduced demand/product output. Based on our calls most of our customers have substantially reduced their workload.

As air compressor system experts, it is our recommendation to keep an eye on rapid cycling that can arise from your system operating at a reduced load.

Rapid cycling is when your air compressor rapidly loads and unloads multiple times per hour.

RAPID CYCLING CAUSES:  
  1. Moisture build up in the coolant, ultimately causing the air-end to fail prematurely
  2. Inconsistent plant pressure
  3. Excessive cycling of compressors (multi-machine systems)
  4. Oil carryover in oil flooded compressors
  5. Rapid wear of inlet valves and other mechanical components
SOLUTIONS:

1) Increase effective storage: This is the first and best solution. Most plants do not operate within the guidelines suggested by most experts, which is 3-5 gallons per CFM of storage.
The following would allow for a smaller tank:
  • Steady linear flows in the plant
  • Smaller air compressors
  • VFD, IM or Variable Displacement controls
  • Large pressure band for the compressor system
  • Use of a flow controller
    • Adding differential pressure will also increase the effective storage. Doubling the PSID is the same as doubling the storage. However, this is not as efficient as increasing storage.
2) Purchase smaller air compressor: Our experts will work with you to determine if this is the best solution for your current situation. A properly sized air compressor with adequate storage will prevent rapid cycling.

There are other solutions none of which we would suggest unless we have exhausted the above options. Instead, we suggest you bring in an expert to look over your system and make the proper suggestions. Call today to schedule an experienced sales engineer or technician to look over your current operating status and make suggestions.

Selecting the Best Blower for You

There are three main types of blowers and these are; positive displacement lobe, centrifugal, and high efficiency and depending on the size of the application you can tell which blower is right for your operation. For smaller applications the positive displacement lobe blowers are the right option as their output and pressure can be directly governed by the speed in which you run them at. Centrifugal blowers are used in medium or large wastewater treatment applications. These blowers usually run at a constant speed, but the airflow output can be throttled by the inlet valve. For these small to medium sized operations a Gardner Denver IQ blower package would be the right call, and Best Aire is a certified representative for Gardner Denver.

For the applications that require a large volume of air, you are going to want to use the last kind of blower that was listed earlier and that is the high efficiency blower. These blowers are ideal as they use magnetic bearing that make it super-fast and allow for the fastest payback on investment. When determining the correct blower size, the most important factors to consider are the load, flow, tank configurations, and the specific application you are considering. Once you have selecting your blower you may consider adding a variable frequency device (VFD) to give you better insight and control over your machine.

For more information about blowers or any of the other products and services that Best-Aire may be able to offer you, feel free to reach out to any of our locations spread across MichiganIndiana, or Ohio. You can also find more information online at www.best-aire.com or give us a call at (800) 968-4422.

Use of Air compressors in the Agricultural Industry

This article will be exploring the importance of air compressors, and choosing the right air house for your company if you are in the agricultural industry. Air compressors have a variety of uses on both animals and produce farms. Taking dairy farms as an example, you would use an air compressor to power the pumps for milking cows or other livestock. Some of the other examples of where you might see and air compressor in this industry include the following. Air compressors might be used for water production, fertilizer, pesticide sprayers, or even to help eradicate greenhouse gases that may have built up. Best-Aire provides a line of oil-less or oil-free compressors as well so that your produce don’t risk any contamination. By investing in an air compressor, you are working towards ensuring your farms daily operations run smoothly.

Another Best-Aire product that can be seen and useful to the agricultural industry are blowers. A blower would be need when you are attempting to move a product such as corn or grain horizontally or up into a silo for storage. Another reason that a blower may be necessary on a farm is that you can use the blower to keep the products in the air while in transit from one location to another. By doing this you are keeping the product from becoming either damaged or contaminated and losing the product. For more information on the products and services that Best-Aire could provide whether you are in the agricultural industry or not, feel free to reach out to any of our location spread across Michigan, Indiana, and Ohio.

Air Audits for your Compressed Air System

When a company is trying to identify ways to lower their compressed air system energy what they will do is referred as an air audit or air demand analysis. The goal is to reduce costs and energy consumption by identifying issues within the air compressor system. At Best-Aire, air audits are just one of the many products and services that we can offer to help our clients meet their objectives. The process of an air audit is comprised of five steps and this article will be discussing each of these steps.

The first step is the conducting of a site survey so that you can list and understand all of the equipment in the compressed air system. You do this so that all measurement devices are properly placed, and system dynamics are properly understood. The second step of the air audit process is measure and quantify matters like kW/100 cfm and determining minimum pressure. The measurement period should include nights, weekends or other downtimes to determine non-productive demands. This is referred to as a supply side audit and is also used to detect leaks or other inefficiencies in the compressed air system. The third step is to understand the systems dynamics with the measurements that have been gathered. During this stage you are analyzing the system information and identifying areas of improvement and coming up with scenarios to lower the system’s energy consumption leading to reduced costs. After analyzing the system info, the fourth step is to recommend or implement the changes to the system that will lead to greater efficiency and reliability and save the client on costs of operating the compressed air system. The final step of the air audit process is the verify performance of the updated system through a post audit check.

For additional information about air audits or any of the services Best Aire can provide feel free to reach out to any of our locations spread across Michigan, Indiana or Ohio.

Air Compressor Lubricant - Why Make the Switch to Best Aire Platinum

Why Make the Switch to Best Aire Platinum

Through the work of Summit Industrial Products, Best Aire is happy to introduce you to our very own line of air compressor lubricant Platinum. Platinum is specifically formulated to outperform other synthetic compressor lubricants on the market. A common problem that compressor lubricants experience is due to high temperatures and discharge pressure accelerating the oxidation process to oil can start to form varnish or sludge and hurt the efficiency and performance of the blower. However, Platinum employs a unique base stock that allows for improvements in both oxidation resistance and compressor cleanliness. Platinum has proven capable of eliminating varnish sludge, and carbon deposits better than traditional synthetic base stocks when tested. Platinum has met the challenge under field condition tests with over 12,000 hours of service and beyond in high temperature applications.

Now that you have an introduction to Platinum let’s look at some key reasons to protect your air compressor with this product. Firstly, as was discussed previously the use of platinum provides increased reliability and operational safety. With an oil that is keeping your air compressor running longer and cleaner you will see an increased longevity of your system as well as increased profitability as service and oil are not needed as often. Platinum oil is an environmentally friendly product with extended drain intervals that result in less volume and cost associated with lubricant disposal. A final advantage of making the switch to platinum is that our synthetic lubricants offer significant economic advantage by improving thermal and mechanical efficiency to lower your energy costs.

If you have any questions or would like additional information about Platinum or any of the other products and services Best Aire could offer you we would love to hear from you. Our website is www.best-aire.com and we have multiple branches located throughout Michigan, Ohio, and Indiana.

Maintenance Requirements - Rotary Screw Air Compressors

Essentially, there are four service milestones that need to be completed on your air compressor:

  1.  Weekly
  2. Minor (2,000 hours)
  3. Interm (4,000 hours)
  4. Major (8,000 hours)
The Weekly Service is just as it sounds, should be completed once a week. At this point you want to check all filters and oil level. Additionally you will want an ideal differential reading from sump to delivery pressure of 2 - 6 PSID. If this is greater than 8 PSID then you might have a dirty separator, the check valve might not be opening or you may have a transducer issue.

During the 2,000 Hour Service you will be submitting an oil sample, especially if your air compressor is presently under warranty. If your are running food grade oil, you will want to perform this test every 1,000 hours. Upon your sample being processed, you will receive a report back stating your oil's TAN number, which is essentially indicates the oil life left. Additionally, if this is the first 2,000 Hour Service, you will want to check all electrical connections, as the heating and cooling of the wires may affect the tightness of the connections. 

During the 4,000 Hour Service you will be removing the separator and examining and cleaning the Scavenger line. If this line gets blocked or clogged, it ill carry over oil into the air supply. In addition, you will perform all steps in both the Weekly Service as well at the 2,000 Hour Service.

During the 8,000 Hour Service you will be examining the inlet valve. Anytime you replace the inlet valve you will also be replacing the valve body, spring, check valve and the air filter.  Additionally, you will be performing all steps in the Weekly, 2,000 Hour, and 4,000 Hour Services listed above.

Us at Best Aire would love the opportunity to earn your business. Please contact us to see what we can do to serve you. We have locations in Grand Rapids, MI, Toledo, Ohio, Detroit, MI and Indianapolis, IN.
