A $10 billion diesel engine manufacturer had been using the same standard-capacity HEPA filters for years. The AAF partner supplying the filters realized the plant was missing opportunities for energy savings. They worked with an AAF representative to uncover potential savings with an upgrade in filters and AAF’s Total Cost of Ownership (TCO) Diagnostic program.
All air handling units at the customer’s plant are equipped with variable frequency drives. Most units run at 100% of the supply VFD to receive the required airflow — and the standard HEPA filters the plant was using had very high initial resistance values. The standard filters were physically bulging under the stress of the airflow.
Based on AHU.R.09 system readings, the supply kW was 44.8. At $0.06 kW/h, that added up to $23,547 per year in energy costs!
AAF and the filter supplier recommended replacing the standard HEPA filter with a MEGAcel l eFRM filter. The high-performing MEGAcel filters feature a uniquely durable FluoroResin Membrane and combine ultra-high efficiency with extremely low-pressure drop. The lower initial resistance significantly reduces energy consumption which can lead to substantial energy savings and cost benefits. The customer agreed to install the MEGAcel I filter in AHU.R.09 on a trial basis.
A thorough air filter audit of your HVAC systems is the first step that AAF takes, in order to provide you with HVAC energy analysis for cost savings. In this way, we identify how your filtration system can optimally perform. Contact us to find out more about lowering your HVAC cost.
Compared with micro fiberglass media, eFRM membrane media provides superior benefits, including inert chemical properties, more uniform fiber distribution, smaller fiber diameters, and smaller pore size. As a result, reduced resistance and higher filtration performance provide substantial energy savings.
Targeted to your HVAC total cost of ownership, TCO Diagnostic provides clear insight to find the best filtration options and tailor them to your specific needs for a comprehensive clean air solution – improving air quality, energy savings, and operational flexibility while reducing your life cycle costs.
