1 Preferred Utilities Manufacturing Corp Preferred Utilities Manufacturing Corporation 31-35 South St. Danbury CT www.preferred-mfg.com Oxygen Trim Overview

2 q Introduction q Combustion Experience q ZP Oxygen Analyzer q PCC-III Multiple Loop Controller q Pricing q Summary

3 In-Situ Oxygen Probe No separate analyzer, one less item to mount Field replaceable probe Only one conduit to stack.

4 q Proven Reliable n Sensing element has been proven reliable in 100s of installation over the last 10 years q No Reference Air n The probe uses ambient air as a reference. n Competitors use instrument air and run the risk of element cracking due to water q Automated, menu driven pushbutton calibration. q Fully automatic calibration package available. In-Situ Oxygen Probe

5 q Thick cell n Avoids premature cell failures q Ceramic heater n provides reliable long life q Complete detailed diagnostics q Automatic impedance checking n Alarms when time to recalibrate n Alarms when reaching end of cell life q Optional fuel gas temperature element / T/C input In-Situ Oxygen Probe
