WHAT IS THE DIFFERENCE BETWEEN A REGULAR ECONOMIZER AND CONDENSING ECONOMIZER?
The difference is the temperature range in which the economizer is operated. Our units may look identical in outward appearance, but can be used in a condensing application if originally design to do so. A traditional economizer is operated in a hot environment, the tubes and the flue gases are over 200F. A condensing economizer operates in a cool environment, where the tubes and flue gasses may be well under 200F. A large savings increase occurs when the flue gas temperature is decreased to under 135F, but this is only effective when burning natural gas.
