During the elevated heat treatment process, when the heat level within the structure has been elevated to lethal temperatures for the pest, the structure can be pressurized by opening the Modulated Air Inlet Gate to draw some fresh air from outside the heated structure to pressurize
the structure causing the heat to penetrate the opening where the pests might be taking refuge from the heat. The fresh air is blended with the heated air and discharged at the set point temperature. This same process can be used in the water remediation process with some simple changes, the
discharge temperature might be reduced and when the recirculated airflow becomes warm and moisture laden, a window is opened to purge the warm moist air from the structure. The Modulated Air Inlet Damper is lowered into the injection chamber to increase the purging air volume.
