Compressed air is an energyintensive resource \u2014 one of the most expensive to run \u2014 and it can account for a significant portion of a company\u2019s energy consumption.  <\/p>\n<p>A methodical approach to optimizing an air compression system can yield valuable benefits in terms of energy efficiency, product quality and operational uptime. Conversely, when a system fails to function properly, it can lead to wasteful spending, damaged products, and worst of all, production breakdowns.  <\/p>\n<p>Justin Beckett, field technician and support specialist with ELGi, outlines a smart approach to optimizing <a href=\"https:\/\/www.elgi.com\/us\/air-compressor-products\/\">air compression systems<\/a> for energy savings. It begins with ensuring a system is properly sized and configured for the job at hand and extends all the way through to utilizing smart technologies for maximum system control.  <\/p>\n<\/div>\n<div class=\"elgi-blog-single-item\" id=\"articleTwo\">\n<h2>The cost of a mismatch  <\/h2>\n<p>Oversizing an air compression system is a common mistake. Running a larger air compressor than what is necessary results in excess energy usage. Larger units cycle on\/off more frequently, drawing inrush current each time they start, causing spikes in electricity use. This cycling also causes more wear and tear on compressors, shortening their lifespan and increasing their maintenance needs.  <\/p>\n<p>\u201cEveryone always thinks bigger is better \u2014 it\u2019s not,\u201d Beckett said. \u201cRunning a 100 hp compressor when you only need 50 hp is just doubling up on the energy required to run it. The compressor will constantly load and unload the pressure in the tank, drawing inrush currents each time it cycles. This is more expensive for the company, and it wears out the compressor much sooner.\u201d <\/p>\n<p>Running an air audit to determine the proper sizing of an air compression system is a best practice for ensuring energy efficiency and extending compressor lifespan. For a system already running, ELGi\u2019s controller software can generate utilization metrics that show how often a compressor is cycling. If it loads\/unloads more than 100 times an hour, that\u2019s a red flag for oversizing. <\/p>\n<p>It&#8217;s not just the air compressor that needs to be properly sized. Air receiver tanks also need to be assessed. They store <a href=\"https:\/\/www.elgi.com\/us\/\">compressed air<\/a> and serve as a buffer between the compressor and demand. <\/p>\n<p>Insufficient tank capacity forces an air compressor to work harder and cycle more frequently. <\/p>\n<p>Properly sized tanks provide more stable pressure and lower energy use. <\/p>\n<\/p>\n<\/div>\n<div class=\"elgi-blog-single-item\" id=\"articleThree\">\n<h2>Variable Speed Drives for smarter starts <\/h2>\n<p>Air compressors equipped with variable speed drives (VFDs) match airflow to demand in realtime. They ramp up and down instead of switching completely on\/off. This eliminates the inrush currents that occur during cold startups, thereby reducing electricity spikes.  <\/p>\n<p>\u201cIt\u2019s like when you\u2019re driving a car. A lot of times, you\u2019ll ease up on the gas rather than coming to a full stop,\u201d Beckett said. \u201cIt\u2019s easier on the system and uses less energy.\u201d  <\/p>\n<p>Even when the air compressor isn\u2019t being used for a short period \u2014 like during a shift change, cleaning period, etc. \u2014 the VFD stays on but throttles down to an idle speed rather than completely shutting off. Air compressor with VFDs work particularly well in systems with fluctuating air demands.  <\/p>\n<\/div>\n<div class=\"elgi-blog-single-item\" id=\"articleFour\">\n<h2>The power of multi-unit configurations    <\/h2>\n<p>Some facilities opt for configurations with multiple compressors to optimize their energy usage. A setup like this would include one fixed-speed compressor and one VFD \u201ctrim\u201d unit. The fixedspeed compressor handles the facility&#8217;s steady demand, while the VFD automatically adjusts with fluctuating demand.   <\/p>\n<p>More advanced setups utilize three or more air compressors working together. They adjust to fluctuating demand, or they facilitate more complex production requirements.  <\/p>\n<p>\u201cMulti-unit configurations help companies avoid over-reliance on a single \u2014 and often oversized \u2014 air compressor,\u201d Beckett explained. \u201cIt also helps future-proof their systems by adding flexibility for growth or evolving production needs.\u201d  <\/p>\n<p>Redundancy can also be the goal of multi-unit configurations. When one unit needs service, the other compressors take on demand. Whether it be for system outages or planned maintenance, this helps facilities avoid production downtime and keep operations running smoothly.  <\/p>\n<\/div>\n<div class=\"elgi-blog-single-item\" id=\"articleFive\">\n<h2>Smart control    <\/h2>\n<p>Multi-unit systems are typically operated by smart master controllers that bring compressors on and offline to meet current needs. Master controllers prevent the compressors from kicking on all at once in response to a demand spike. They control timing to smooth load balance and avoid overreaction.    <\/p>\n<p>\u201cSmart controllers can be programmed to select which size compressor is best for a given scenario,\u201d Beckett said. \u201cFor example, it can scale back to a 50 hp compressor during lunch breaks instead of keeping a 100 hp unit running.\u201d  <\/p>\n<p>Air compressor owners can also act smartly, of course. Many facilities leave their air compressors running overnight, even when no one is working. This cycling burns energy and shortens compressor life.    <\/p>\n<p>\u201cSmart systems or simple timers work better than managing systems manually. It\u2019s better to automate and eliminate the risk of forgetting to shut the system down,\u201d Beckett said.   <\/p>\n<\/div>\n<div class=\"elgi-blog-single-item\" id=\"articleSix\">\n<h2>Your next move  <\/h2>\n<p>Efficiency doesn\u2019t just come from buying the most powerful compressor \u2014 it comes from buying the right one.
