Take the Steps: Installing Intermediate Storage

Published on by jasonkirbyLeave a comment

Air compressors depend on electricity to generate compressed air, making it essential to enhance the efficiency of your compressed air system. EXAIR offers six straightforward steps that can assist in lowering electrical expenses, minimizing overhead, and boosting profitability. This blog will focus on the fifth step, which involves the intermediate storage of compressed air close to the point of use.

Intermediate storage plays a vital role in managing pressure variations that can arise during production processes. When materials are transferred from one stage to another, sudden changes in pressure can negatively affect the quality of the product. By incorporating intermediate storage, manufacturers can create a buffer that helps stabilize pressure fluctuations. This stabilization ensures that the materials remain consistent before they move on to the next stage, thereby preserving their quality and integrity. Ultimately, this careful handling supports better overall outcomes in the final product, leading to higher customer satisfaction.

In some cases when only one or a few applications need air sporadically, using a properly sized storage receiver can be very helpful. Placing this storage receiver near the point where air is needed most can improve efficiency. It is essential to include a check valve and metering valve with the storage receiver. The check valve ensures that air does not flow back, while the metering valve controls the rate of refilling which is another strategy for reducing overall load on a compressor.

Receiver tanks play an important role in providing compressed air for tasks that require a lot of air for a short time. By placing these tanks in the right locations, users can ensure a steady supply of air without always depending on the compressor. This setup allows for more efficient operations during peak demand periods. Properly sizing the tanks is crucial, as it ensures they can deliver the right amount of air when needed. Overall, receiver tanks enhance the performance of compressed air systems and help meet varying demands effectively, and with a more consistent result.

Step Five of our Six Steps To Optimizing Your Compressed Air System: Use intermediate storage near the point of use.

EXAIR provides a 60-gallon receiver tank that is ready for immediate use. This tank is designed for applications that require a lot of air for short periods. The model 9500-60 can be placed close to where you need extra compressed air. By having this tank nearby, you can ensure that there is enough air supply when demand increases. This setup helps maintain efficiency and performance in your operations.

Saving Money with our Super Air Knives

Published on by Al WooffittLeave a comment

Here at EXAIR we are confident that there is a lot to gain from using our products. Two of the biggest benefits of our Intelligent Compressed Air Products are a reduction in noise, and a reduction in Compressed Air usage. The latter will often lead to big money savings. Many times the savings our products offer will pay for the product itself! What is my Return on Investment going to be?

So, how do you calculate your ROI? The easy answer is that you don’t have to! You can use our Air Savings Calculator to calculate your savings for you. If you know your current air consumption (in SCFM), the new air consumption (SCFM) and the cost of the product, our calculator will turn that into monetary savings, as well as the calculated payback time in days.

Another option if you would rather not do the calculations yourself, is that you can send the item in question to our Efficiency Lab Testing. The Efficiency Lab Testing is a free service that we offer to show you the possible savings by switching to one of our products. We will calculate the savings for you and send you the results of our findings.
The final option – my favorite by the way – is that we can do the math right here:

For a simple example, I’m going to show the ROI of replacing a drilled copper pipe with an EXAIR Super Air Knife for a blowoff application. The calculations will be as follows:

Copper Pipe (1/4”): 3x 3/32” diameter drilled holes uses 9.4scfm per hole (28.2scfm total) at 80psig.

3” Super Air Knife: uses 8.7scfm at 80psig

Calculation:

For the yearly consumption, we need to find how many minutes in a year the blowoff will be operated:

For the Copper Pipe:

For 3” Super Air Knife

The difference between these two:

At this point, if you know your facilities cost to generate 1,000scf, you can use that to calculate how much you would save. For this example, we will use $0.25 to generate 1,000scf, which is used by the U.S. Department of Energy to estimate costs. This gives the following yearly savings:

With an investment of $273.00 (at the time of publishing), you can calculate the time it would take to pay off the unit:

From these numbers you can see that after 117 days, the 3” Super Air Knife will have paid for itself.

As you can see, it doesn’t have to take long for the knife to pay for itself, and then continue to contribute toward your bottom line.

Conducting A Compressed Air Audit

Published on by jasonkirbyLeave a comment

The primary objective of a compressed air audit is to establish a strategy for enhancing energy output in relation to system efficiency. According to the U.S. Department of Energy, approximately 50% of the compressed air produced is lost. Additionally, it is estimated that leaks within the system can lead to a 25%-30% increase in compressed air consumption. Conducting a compressed air audit can enhance system reliability, prolong the lifespan of equipment, and reveal areas for potential improvement.

To conduct an air audit, you need to systematically assess a compressed air system by identifying and measuring air leaks, checking air filters, evaluating air quality, analyzing system operational data, performing visual inspections, and ultimately creating a plan to optimize energy use and identify areas for improvement within the system; this typically involves using tools like flow meters, pressure gauges, leak detection devices, and dew point monitors.

Create Checklist: To initiate your checklist, it is essential to first establish the scope of the audit. Identify the specific elements of your compressed air systems that require evaluation, including the compressor, dryer, receiver, filters, piping, and end-use equipment. Subsequently, determine the depth of detail and the type of data necessary for collection, as this will form the foundation of your checklist.

Review Data: Gather information regarding the compressed air equipment, encompassing compressor specifications, usage patterns, maintenance logs, and air quality metrics. Furthermore, it is essential to examine the installation, operation, and maintenance manuals of the equipment to verify adherence to the manufacturer’s recommendations.

Visual Inspection: Perform a visual examination of the equipment and its environment. Utilizing your compressed air audit checklist, assess for any leaks, damage, corrosion, or signs of wear, and evaluate these findings alongside other equipment. This process guarantees that safety mechanisms, including pressure relief valves and gauges, are properly installed and operational.

Air Quality: Assess the air quality within the compressed air system. Investigate for the presence of oil mist, water, and particulate contamination in both the system and the product, and verify that air treatment devices, including dryers and filters, are properly installed and operating effectively.

Operating Procedure: Examine your operational protocols and optimal practices with equipment operators. Assess potential avenues for decreasing air leaks, enhancing air pressure efficiency, and reducing energy waste. Furthermore, contemplate the adoption of an energy management system to oversee and regulate compressed air consumption.

Prioritize Needs: The maintenance and repair requirements of the compressed air system should be established based on the audit results. It is essential to prioritize the identified concerns and formulate a strategy for their resolution. Subsequently, responsibilities should be allocated to appropriate personnel, and timelines for completion must be set.

Review: It is essential to regularly review and update your compressed air audit checklist to ensure it accurately represents any changes in the system and the facility’s operational procedures. Adjustments should be made in response to findings from prior audits as well as input from equipment operators and maintenance staff.

If you must use quick connects, the 1/4 turn claw type (left) is the least restrictive. Push-to-connects (center) are likely to starve your product, unless you oversize them (right) like we do in our Efficiency Lab.

To ensure optimal performance of your EXAIR Intelligent Compressed Air® product, it is essential to provide a consistent flow of compressed air at the ideal pressure. Factors such as the output pressure of the compressor, the airflow rate, the inner diameter of the piping, the internal smoothness of the pipes, and the type of connectors all play a significant role in determining performance.

In manufacturing applications, it is crucial to evaluate both the air pressure and airflow generated by the air compressor that supplies all tools. An air compressor may deliver sufficient supply pressure for an EXAIR product, yet it might not provide adequate airflow for prolonged use of the product.

A properly engineered compressed air distribution system can enhance efficiency by as much as 30%, resulting in significant annual energy cost savings. Hoses, tubing, and fittings play a crucial role in any compressed air system, similar to the pipes that convey compressed air to its final destination. Typically, these components are utilized between the compressor and the piping or between the piping and the application. Although they constitute a minor portion of the overall system, they often receive insufficient consideration, which can lead to pressure loss at the point of use if not appropriately chosen or maintained. To avoid unnecessary pressure drops and potential production losses, it is essential to take into account several key factors when selecting hoses, tubing, and quick disconnect couplings.

A pressure drop is when there is a reduction in air pressure within an air compressor system. The pressure drop can happen anywhere between the compressor discharge and the actual point of consumption. The pressure drop varies on the type of industry and application of air compressors. The extent of this pressure drop increases with smaller pipe diameters and longer lengths. Additionally, fittings can considerably affect system performance by decreasing the effective flow area.

EXAIR products are designed to improve the overall efficiency of your operations. If you need help and have questions, please contact any of the Application Engineers. There is no risk to trying our products as we have a 30-day Guarantee for all of our US and Canadian customers.
