Regular review of your compressed air energy efficiency is critical for achieving optimal performance and reducing the need for expensive repairs and downtime. It will help you get the most out of your system, improve business operations, and save on utility bills.

Methods like producing your own nitrogen can help you keep energy efficiency down. Below are five reasons to review compressed air energy efficiency on an annual basis:

Establish Your Baseline Numbers

The energy consumed by your compressed air system is measured in two different units:

  • Kilowatts (kW), which is the raw amount of power consumed
  • Kilowatt hours (kWh), which is the standard unit for understanding consumption

When you understand the energy being consumed in these units, you can establish how much energy is required to power your operations under normal conditions. If the baseline number is not close to the manufacturer’s recommendation, there may currently be a problem within your compressor system that needs to be addressed.

As the cost-per-kilowatt has increased since 1980 and increased sharply in 2020, it is important to assess these costs and make changes based on them.

Observe Changes In Production

If the energy expenditures don’t rise and fall with production levels, it might be time to make some changes. For example, your compressor doesn’t need to be working as hard if overnight or weekend production levels aren’t as high as they are during the day. This is a sign that your compressor is working hard at times that it doesn’t need to be.

If the schedule changes seasonally, or has grown due to demand, it is time to re-evaluate your energy needs.

Upgrading Or Sizing New Equipment

If you’re considering upgrading compressor equipment, it helps to know current energy expenditures so that you can better determine the needed equipment. Data loggers can provide a snapshot of operations to remove the need for guesswork or assumptions. Having a clear understanding of your energy needs is important as you look to make changes to your system.

Preventative Maintenance Benefits

Energy efficiency reviews can help address issues early on, before they lead to larger problems. This reduces the risk of costly breakdowns or repairs and can reduce downtime to the system. Understanding the energy efficiency of your system and making sure it’s optimized can extend the lifespan of your air compressor.

Increased Productivity

An efficient air compressor provides a reliable air supply. This allows for higher output and reduced production bottlenecks. Predictability within the system allows for more informed decision-making and more productivity. Regular energy efficiency reviews can help you keep your air compressor working as efficiently as possible.

Routine Compressor Maintenance Is A Must

Your air compressor is an important investment in the productivity of your company. It’s important to keep up with preventative maintenance so that you can get the most from that investment as possible.
