Want to Know How Much Money you can Save? Use EXAIR’s Efficiency Lab

Growing up as a kid of the 80’s I remember wanting a Nintendo 64. This was very much a want due to the excellent advertising and having friends that got them when they first came out. So, like many kids of the times, I set forth to present my case to my parents and sell them on the benefits to me receiving this 64 bit wonder of the world. These benefits all revolved around me doing chores and “helping” to earn money to go towards the end goal. Thinking back now, I really should have started to learn more about negotiating earlier in life because my parents and older brother really made out on the deal. The point is, I had to make sure that they saw a return on their investment. Mainly, I would be entertained and they would get some stuff done around the house without complaints.

Well, flash forward to today and I still feel as though it is always an easy justification if I have supporting evidence of the benefits and even better, if there is some form of cost savings that will be had by spending money on a project or a tool. Often times the justification is the amount of time spent on a task. Well, here at EXAIR we completely embrace that justification culture and, in many cases, can provide you the information necessary to present to management or budget committee – the simple ROI your company will see when investing in EXAIR products. The best part is, this study is always free.

The way it works is pretty simple, we want to compare your current solution to our engineered products. EXAIR has a simple form that gets filled out (or you can call, e-mail or chat) explaining your application to us. We ask for a few key pieces of detailed information, and for you to send one of your current solutions (the nozzle, homemade device, or open tube for example). Then we run side by side tests in house to determine air consumption, noise, and force at the same pressure you are using at your facility. That’s right, this testing is all done here at EXAIR through our EXAIR Efficiency Lab. We document these performance characteristics and send a report showing a simple return on investment for you if you replace your device with an EXAIR engineered solution.

Optimizing Your Compressed Air System in 6 Steps!

If you’re a follower of the EXAIR Blog, you’re probably well aware that compressed air is the most expensive utility in an industrial environment. The average cost to generate 1000 Standard Cubic Feet of compressed air is $0.25. If you’re familiar with how much air you use on a daily basis, you’ll understand just how quickly that adds up. To make matters worse, many compressed air systems waste significant amounts of compressed air just through leaks. According to the Compressed Air Challenge, a typical plant that has not been well maintained will likely have a leak rate of approximately 30%!! Good luck explaining to your finance department that you’re carelessly wasting 30% of the most expensive utility. To make sure you get the most out of your compressed air system, it’s important to follow the Six Steps to Optimizing Your Compressed Air System.

Starting with Step 1: Measure the air consumption to find sources that use a lot of compressed air. In order to have an understanding of your compressed air usage across various processes and in your entire facility, you have to measure and produce a baseline. Without a measurement of usage, there’s no way to determine your actual costs or evaluate opportunities for savings. To do so, EXAIR offers a range of Digital Flowmeters from stock. The Digital Flowmeter provides a digital readout of the exact amount of compressed air being used. Many companies will install the DFM on each major leg of their air distribution system to allow for constant monitoring and provide a benchmark of compressed air usage.

Once you’ve measured your baseline, it’s time to explore another simple avenue of savings. Step 2 in the process is finding and fixing leaks in your current system. EXAIR offers our Model 9061 Ultrasonic Leak Detector to allow you to locate and fix any leaks within your distribution system. With an unmaintained system wasting on average 30% of the produced volume, this one seems like a no-brainer but is often overlooked. If you can hear the leak without the help of a device like the ULD, it’s a VERY bad leak. These should be located, tagged, and repaired ASAP!

After getting a baseline measurement of the air consumption in your facility of compressed air usage and locating and fixing leaks in your system, it’s time to begin implementing some changes. Step 3 of the 6 Steps to Optimizing Your Compressed Air System covers upgrading your blowoff, cooling, and drying operations using engineered compressed air products. EXAIR manufactures a variety of products that can help to ensure you’re using your compressed air in the best way possible. While it may seem simple, easy, and cheap to use something like an open-ended pipe or tube for blowoff, the fact of the matter is that the volume of air that these homemade solutions use quickly make them more expensive. Look no further than EXAIR when seeking a safe, efficient, and reliable engineered blowoff solution.

EXAIR Intelligent Compressed Air Products such as (left to right) the Air Wipe, Super Air Knife, Super Air Nozzle, and Air Amplifier are engineered to entrain enormous amounts of air from the surrounding environment.

Step 4 may be the easiest of any of the others. TURN IT OFF! You can’t waste compressed air when it’s turned off. By strategically placing valves at various points throughout the distribution system, it allows you to isolate areas of the facility that may not require continuous compressed air usage. It isn’t exactly feasible to eliminate every single leak, so even if you’ve closely followed Step 3 it’s still beneficial to close some valves here and there to further reduce your consumption. In some applications, such as products traveling on a conveyor, it may be possible to utilize a product like EXAIR’s Electronic Flow Controller to ensure air isn’t wasted in between parts on the conveyor.

The 5th step in the 6 steps to optimizing your compressed air system highlights the use of intermediate storage of compressed air near the point of use. Receiver tanks are installed in the distribution system to provide a source of compressed air close to the point of use, rather than relying on the output of the compressor. Compressed air receiver tanks are an integral part to many compressed air distribution systems. Compressed air is stored at a high pressure after drying and filtration, but just upstream of point of use devices. The receiver tank is charged to a pressure higher than what is needed by the system, creating a favorable pressure differential to release compressed air when needed.

Think of a compressed air receiver tank as a “battery”. It stores the compressed air energy within a system to be used in periods of peak demand, helping to maintain a stable compressed air pressure. This improves the overall performance of the compressed air system and helps to prevent pressure drop. They should be placed strategically to provide a source of compressed air to intermittent high-volume applications.

The last step, Step 6, discusses the use of pressure regulators at the point of use. Pressure regulators are available to control the air pressure within the system and throttle the appropriate supply of air to any pneumatic device. As the last of the six steps to optimizing your compressed air system, controlling air pressure so that you’re only consuming as much as necessary can have a dramatic impact. EXAIR sells a variety of systems that will include a suitably sized pressure regulator to ensure you’re operating as efficiently as possible.

Follow these 6 steps and make sure you get the most out of your compressed air system!

EXAIR Digital Flow Meters

A topic that we’ve talked about here on the EXAIR blog discusses the costs of compressed air and how to use it more efficiently. How can you determine the costs of your compressed air? The first step you’ll need to take is to put a number to how much compressed air you are currently using. In order to do that you’ll need a measurement tool such as the EXAIR Digital Flowmeter.

EXAIR Digital Flow Meters

The Digital Flowmeter is available from stock for use on Schedule 40 pipe with sizes ranging from ½”-4” I.D. Sizes up to 8” for Schedule 40 and ¾”-4” for copper pipe are also available. Metric sizes are also available for 25mm, 40mm, 50mm, 63mm, 76mm, and 101mm. With a digital readout display, it’s easy to accurately monitor your compressed air usage throughout the facility. Creating a baseline of your usage will allow you to understand your compressed air demand, identify costly leaks, and replace inefficient air products.

The Digital Flowmeter installs in minutes with help from a drill guide and locating fixture to assist in mounting the Digital Flowmeter to the pipe. Two flow sensing probes are inserted into the drilled holes in the pipe. The meter then seals to the pipe once tightened. There is no need to cut, weld, or do any calibration once it is installed. With blocking rings also available, installation can be permanent or temporary. Below is a easy to follow video on how to install EXAIR’s Digital Flow Meter!

The newest addition to this product line is the Digital Flowmeter with wireless capability. Using a ZigBee® mesh network protocol, data is transmitted to an Ethernet connected gateway. This allows you to mount the Digital Flowmeter in areas that you may not be able to easily access and wirelessly monitor and graph the usage with the EXAIR Logger software. Take a peek at this video blog for a demonstration of the use of a wireless Digital Flowmeter software to compare an open pipe to an engineered Air Nozzle.

Wireless output gives you the freedom to track air usage data from any computer!

In addition to communicating wirelessly with the gateway, the Digital Flowmeters can “piggyback” off of each other to extend their range. Each meter has a range of 100’. Using multiple Digital Flowmeters within the same ZigBee® mesh network, data can be passed from meter to meter to extend the distance over which the meters can operate. These can be installed on each major leg of your compressed air system to continuously monitor usage throughout the facility.

If you’d rather go with a hard-wired data collection method, the Digital Flowmeter is also available with a USB Data Logger. Simply remove the Data Logger from the Digital Flowmeter and connect it to the USB port of your computer. The data can then be viewed directly in the accompanying software or exported into Microsoft Excel.

Two special flow meter options we now offer are the Pressure Sensing Digital Flowmeters, and the Hot Tap Digital Flowmeters!

Pressure Sensing Digital Flowmeters help by generating a pressure and consumption profile of a system can help to pinpoint energy wasters such as timer-based drains that are dumping every hour versus level based drains that only open when needed. Hot Tap Digital Flowmeters offer a way to install a flow meter on a pipe that is currently under pressure. It uses a series of valves and mufflers to maintain a safe working environment for the installer.

If you’d like to get a clear view of your compressed air usage, give us a call. An Application Engineer will be happy to work with you and get the proper Digital Flowmeters installed in your facility!
