Koch Filter saves Dow $156,000 by improving airflow to turbines

Project Scope

Koch Filter Corporation evaluated the turbine operation at a Dow Chemical facility. They determined that
the gas turbine's air intake system was undersized and pre-filters had an initial resistance that was too
high, causing the turbine to be "starved" for air. Koch replaced these filters with a better filter that
eliminated the problem.

Project Summary

Koch Filter Corporation converted the pre-filters on Dow's gas turbine to Koch's Multi Pleat GT-HD Pre-
filters. The lower air resistance enabled Dow to realize energy savings of $156,000 annually. Besides
the energy savings, Dow was able to extend filter-change life cycle time from 3 months to 6 months, and
reduce filter costs by 35%.

•	Energy Savings
$156,000 per year

•	Investment

35% less than the cost of the original filters

•	Financial Return

Immediate - no additional investment costs were required to produce the savings

•	Other Benefits

Extended filter life, reduced labor costs for change-outs, increased production uptime, and
reduced landfill costs

Monitoring & Verifying Energy Savings

Dow has replaced filters at the new change interval, and has determined that the new filters are
performing as designed.

Distinguishing Value

Koch Filter Corporation responded to Dow's need to decrease energy cost and extend filter life cycle. In
addition, Koch has been able to produce subsequent replacement filters in a timely manner, eliminating
costly shut-downs of the gas turbine.
