Advantages/Disadvantages 6. CONVERT STEAM AIR MAKE-UP UNITS
This emerging technology is the only way to TO NATURAL GAS
get efficiencies in the mid 90% range. Special de-
signs are required, most installations have been
highly successful. Acid formation does not seem 7. REDUCE INFILTRATION AIR

8. SHUT-DOWN ExHAUST FANS
DURING OFF PRODUCTION PERIODS
Standard Practices

3. INSTALL TEMPERATURE SETBACK TO 9. INSTALL HEAT RECOVERY
OPERATE IN OFF HOURS VENTILATORS

10. INSTALL RUN AROUND HEAT
