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.

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!

Back To The Basics: Process Improvement Basics

We understand that it is more important than ever to realize savings within manufacturing processes. EXAIR can reduce compressed air consumption and provide simple ROI in a matter of weeks in MANY cases.

In the hustle and bustle of the daily grind wherever you are, there are certain processes that become muscle memory for you and certain processes that just work and don’t need any attention. Whether it be a login process for your computer network, the number of steps it takes to fill your coffee cup, or the compressed air applications in your facility.

You know what I am talking about, these items begin to get glanced over and often become overlooked. When going through process improvements or troubleshooting, it is easy to overlook processes which are not causing trouble or that have become “acceptable” because they are producing. EXAIR firmly believes compressed air applications are ripe for improvement, and our product lines are built to replace inefficient compressed air products with engineered and efficient solutions.

When evaluating a process for improvement creating a baseline is the necessary start. With this, we can then start to draw a realistic target of where the process needs to be in order to be optimized and document the changes from our starting baseline.

Much like the 6 Steps to Compressed Air Optimization, which starts with measuring compressed air consumption to provide a baseline.  Sometimes, this may require the installation of a Digital Flowmeter, others it may include taking advantage of our Efficiency Lab service for us to get a baseline of what air consumption and other key performance indicators are for your application.

Looking to “go green?” We can help.

Once we have the baseline and a target, we can then begin to design an improvement process. Whether this is implementing better controls for the air, such as pressure regulators, or implementing controllers such as the Electronic Flow Control, it may even be simply installing an engineered solution.  Once an improvement has been implemented we can then go on to the next testing phase to again gather data to see how much air was saved from the baseline.

EXAIR’s Free Efficiency Lab

Once the performance of the new process is determined then we can take the new cost of ownership numbers and give a simple return on investment back to determine what the actual savings by implementing these process improvements have amounted to.

The below example is from a customer who had already improved their static elimination application by using our Super Ion Air Knife instead of a homemade pipe with drilled holes. They further optimized the application with our Electronic Flow Control.

Pressure Gauges – Why You Need Them & How They Work

There is hardly a day I work that I am not talking about the importance of properly installed pressure gauges.  These small devices can often get overlooked or thought of as not necessary on an installation.  When troubleshooting or evaluating the compressed air consumption of an application, this is one of the first items I look for in the installation.

As Russ Bowman shows in the above video discussing proper piping sizes, you can see the importance of properly placed pressure gauges.  This shows the worst-case scenario where the pressure drop due to improper line sizes gives the false sense to the operator that they are achieving full line pressure when in fact they are not.  In order to accurately measure consumption rates, pressure AT THE INLET (within a few feet) to any compressed air product is necessary, rather than upstream at a point where there may be restrictions or pressure drops between the inlet and the gauge. So how exactly do these analog gauges measure the pressure of the compressed air at the installed locations?

Pressure Gauge Model 9011

The video below shows a great example of pressure increasing and decreasing moving the Bourdon tube that is connected to the indicating needle.  The description that follows goes more in-depth with how these internals function.

Most mechanical gauges utilize a Bourdon-tube. The Bourdon-tube was invented in 1849 by a French watchmaker, Eugéne Bourdon.  The movable end of the Bourdon-tube is connected via a pivot pin/link to the lever.  The lever is an extension of the sector gear and movement of the lever results in rotation of the sector gear. The sector gear meshes with spur gear (not visible) on the indicator needle axle which passes through the gauge face and holds the indicator needle.  Lastly, there is a small hairspring in place to put tension on the gear system to eliminate gear lash and hysteresis.

When the pressure inside the Bourdon-tube increases, the Bourdon-tube will straighten. The amount of straightening that occurs is proportional to the pressure inside the tube. As the tube straightens, the movement engages the link, lever, and gear system that results in the indicator needle sweeping across the gauge.

If you would like to discuss pressure gauges, the best locations to install them, or how much compressed air an application is using at a given pressure, give us a call, email, or chat.
