Variable Speed Drives
Save Money utilizing Variable Speed Drives
When fixed-speed drives are used to meet a variable demand, you risk inflated utility bills and excess energy usage. APenergy collaborates with manufacturing plants and facilities to ensure they get the most out of their systems while maintaining energy-efficient operations.
Variable speed control boxes offer power switching and protection, adjustable speeds, visual control, and security protection for your industrial applications and HVAC systems. APenergy works with industrial manufacturers to ensure their operations utilize the potential of Variable speed drives when applicable.
Last year, an industrial manufacturing facility reached out to us for an energy audit of their three coolant pumps. From this audit, they hoped to identify potential projects or Energy Conservation Measures (ECMs) where energy, resources, and costs have the potential for reduction. ECMs are proposals for individual projects, each requiring individual engineering and project development. The audit also identifies opportunities with the potential to immediately impact the plant with minimal or no cost of implementation.
After performing the energy audit, our highly skilled technicians suggested that the facility should implement new VFDs on their three 100hp pump applications. The facility only operates two of these pumps at a given time. These applications were throttled to 35% and 65% open, and they were pulling full load power. By implementing VFDs, users can control the flow by providing variable speed pump operation. This results in reduced system pressure and function, and maintenance costs will also be reduced.
The total for completing the recommended project came to a cost just under $100,000. This figure represents a simple payback period of approximately 2 years. A comprehensive annual energy reduction of 700,000 kWh/year was achieved through the implementation of the ECM.
Variable speed drives provide many benefits for industrial applications and heating and cooling systems, but only if they’re working to their fullest potential. At APenergy, we partner with industries looking to save money and reduce their facility’s energy consumption.
The APenergy process starts with an energy analysis to determine where there may be gaps or inconsistencies in your industrial applications. After auditing your systems, our energy experts consult with you to develop an implementation plan with quotes on equipment and contractors. But don’t worry—we’re not leaving you there.
We know how expensive changes to your facility’s systems can be. That’s why we find utility and funding incentives for our clients that fund 20% to 100% of the project. Ready to save money and promote a more energy-efficient building? Reach out to APenergy today to get started!
Independent and brand-neutral, our loyalty lies with delivering the best results for the client. Count on APenergy to deliver the solutions to optimize your energy usage.
