Did you know that 12% to 40% of a facility’s total energy cost comes from compressed air systems? That makes improving air system efficiency one of the best ways to save money long-term. Beyond basic tactics like leak repair or reducing pressure ranges, here are five powerful strategies to further boost your system’s performance:
1. Recover Waste Heat
Oil-injected screw compressors can recover up to 70% of their energy as heat, and oil-free water-cooled units up to 94%. This reclaimed heat can be used for space heating, water heating, or production processes—reducing the need for additional energy sources.
2. Choose the Right Size Equipment
Improperly sized compressors lead to inefficiency. Ask yourself:
- What is the required flow rate and minimum pressure?
- Is there variation in air demand between shifts?
- Will production expand in the future?
Choose equipment based not just on initial cost but total lifecycle cost, including maintenance and energy usage.
3. Upgrade Your Compressor or Controls
New compressors come with high-efficiency motors and advanced digital controllers. If your current unit is still in good shape, consider retrofitting smart controllers or key components to reduce idle time and energy loss.
4. Use the Right Compressor Type
In industries like food, pharma, and electronics, oil-free air is critical to maintaining product purity and avoiding contamination. Switching to oil-free systems also reduces filter replacements and condensate treatment costs.
5. Add VSD Technology
Variable Speed Drive (VSD) compressors match output to demand, avoiding idle energy use. They can cut energy costs by 35% to 50%—especially effective in facilities with fluctuating air demand.
Summary
To optimize compressed air efficiency, invest in the right technologies, maintain regularly, and choose equipment wisely. At FOOEN Specialty Rental, we’re here to help you find the right solution for high-efficiency compressed air that fits your operations and budget.
