2. 50F5 Modular Ionizers
Ionizer modules can be rack or flange mounted to fresh air inlet duct or recirculation plenum or duct
Power consumption only 50 watts per module
Oxygen present in air flow over tubes becomes bipolar - ionized and reactive
Ionized air flows via HVAC air distribution ducts to building or enclosure
No ozone produced.

4. Heritage Lift Station San Jacinto River Authority The Woodlands, Texas 77380
A very smelly lift station is positioned within a few feet of the property line of a $1M home
End of pipe systems including chemical drum scrubbers and chemical spray systems did not solve the problem
Trans-Tech custom designed and installed an air ionizer system with positive pressure air feed on April 2, 2001
Within minutes the wet well exhaust was clean and odor free.

11. CONCLUSIONS
Bipolar air ionization provides a simple and cost effective odor control solution
Added value includes corrosion control, health and safety advantages
Recommendation: Do not allow simplicity of concept to be misinterpreted as lack of need for thoughtful system design and engineering.
Total costs - capital plus O&M are less than “end of pipe” odor control system alternatives.
