Compressed air systems are the backbone of countless industries, powering tools, production lines, and essential processes. To ensure the efficiency and reliability of the generating equipment, it’s vital that your air compressor system is correctly sized. Both under- and over-sized compressed air equipment typically result in increased Hydro and service costs, pressure issues, and compressed air quality decay. Understanding the unique requirements of your business is crucial too. Do you want to expand operations, improve energy efficiency, increase storage, reduce air leaks, or fix recurring issues.
In this article, we’ll explore the key factors to consider, how addressing air leaks and pressure drops can optimize performance, and how tools like the Air Demand Analysis (ADA) can improve your bottom line.
Why thoughtful assessment matters
Equipment failures and energy inefficiencies can slow down production, frustrate your team, and ultimately lead to significant costs.
Picture this: it’s the middle of your production day, and everything screeches to a halt because your air compressor system can’t keep up with unexpected peak demand. Workers scramble to troubleshoot as production stalls. This is a scenario we’ve encountered repeatedly during compressed air audits and discovery visits.
Properly assessing and preparing for “peak demand” ensures your system is ready when needed the most, preventing costly downtime and stress. A thorough assessment also guarantees that your system meets today’s needs while accommodating future growth seamlessly.
Key factors in evaluating compressed air systems
Pinpointing volume and pressure needs
Think of CFM (cubic feet per minute) as your system’s lungs and PSI (pounds per square inch) as its heartbeat. For instance, facilities using sandblasters require high CFM to maintain operation, while pneumatic presses depend on steady PSI for precision.
Misjudging these metrics can lead to energy waste, inefficient operations, or pressure drops. Overestimating air requirements wastes massive amounts of energy. Underestimating risks operational inefficiencies, and more often than not, downtime. It’s all about balance.
Evaluating power supply
Do you know if your facility can support the power your system needs? Larger compressors typically require 575 volts, while smaller setups might run on 230 or even 115 volts. In our compressed air audits, our team ensures that we match your on site power configurations perfectly. Our air compressors are available in almost any power voltage imaginable.
To ensure motor voltage and premium energy efficiency, Air Solutions Canada evaluates available power supply during site visits, ensuring seamless integration and optimal power consumption.
Managing peak demand
Compressed air systems face fluctuating demands, with peak usage often causing strain. For example, one manufacturing client was shocked to learn their system struggled mid-morning during production surges. Using tools like the Sigma Air Manager and ADA, we were able to map their exact usage patterns. By addressing peak demand, they avoided downtime and significantly reduced energy costs.
Planning for ventilation and heat recovery
Compressed air systems generate significant heat, which, if unmanaged, can shorten equipment lifespan and lead to excessive temperature shut down. Proper ventilation is critical — but there’s an opportunity here too: heat recovery.
For example, we helped an automotive client repurpose their heat of compression to warm their facility in winter, cutting gas-powered heating costs and earning an incentive worth $7,000 through an Enbridge Gas incentive. Another heat recovery option is to preheat process water, boiler pre feed H20, and even washroom and shower water. Facilities that integrate heat recovery often see ROI within a year thanks to utility savings and financial incentives.
Future-proofing for growth
Your operations may expand, and your compressed air system needs to keep pace. Modular systems, like those powered by Kaeser compressors, are designed for scalability, allowing for seamless additions without costly overhauls. We discuss future growth early during discovery visits, designing systems with expansion and energy efficiency in mind.
For instance, we worked with a client planning to expand production within two years. By designing their system with modular inputs, adding capacity was as simple as wheeling in a new compressor and integrating it with the existing setup.
The game-changer: Air Demand Analysis (ADA)
An ADA is like a health check for your compressed air system. It's a compressed air audit that uses advanced monitoring tools to uncover inefficiencies, saving you time and money. Here’s how it works:
- Data Collection: Monitors flow, pressure, and energy usage in real time.
- Air Leak Detection: Measures baseline air use during non-production hours to identify air leaks.
- Custom Recommendations: A detailed report, prepared by a P.Eng, outlines actionable steps to optimize your system—from reducing pressure drops, increasing storage, to improving energy efficiency.
During a compressed air system audit, we discovered a client was losing 30% of their compressed air to leaks. By addressing these inefficiencies we were able to achieve thousands of dollars each year in cost reduction and significantly improved system reliability.
Kaeser energy saving system
Using the Kaeser energy-saving system, KESS, we process the data determined by the ADA, and design a compressed air supply for you that can save up to 30% of your operational costs, and possibly even more!
We then compare several possible concepts in order to achieve the best possible efficiency. We take into account the performance of the station during its overall service life. This means that any weak points in partial load operation can be detected in advance and remedied.
Dispelling myths about compressed air systems
“Cheaper Systems Save Money”
The initial purchase price is just 15% of a system’s total lifetime cost. Energy consumption accounts for 70%, making efficiency a top priority. Many clients focus solely on upfront costs without considering long-term implications. Choosing an energy-efficient system, like Kaeser’s energy saving systems, even if slightly more expensive upfront, results in significant savings over time.
“Bigger is Always Better”
Oversized systems lead to waste and inefficiencies. Overbuilt systems consume more energy than necessary. Right-sizing ensures your system meets demand without overconsumption. For example, during one ADA, a facility discovered they were using a 150hp compressor during a weekly printing preparation day. Our ADA exposed that this size of machine was far larger than necessary. Adjusting to a properly sized, 15hp system resolved inefficiencies and cut operating expenses substantially.
“Is Maintenance Necessary?”
Regular upkeep keeps your system running efficiently, avoiding costly repairs or replacements. Neglecting routine tasks like seasonal damper adjustments, or addressing air leaks, can drastically reduce system performance. Scheduling preventative maintenance and monitoring components ensures consistent performance, extends equipment lifespan, and prevents unexpected downtime.
Assessing your compressed air requirements is key
