ABSTRACT:
A heater blanket for use in soil remediation utilizes a rigid construction which isolates the heater elements from air, water, and contaminant vapors which could act to oxidize, embrittle or otherwise degrade the integrity of the electrical heaters. A rigid structural frame is constructed from a support frame of parallel members which are rigidly connected to a series of support tubes perpendicular thereto. The support tubes enclose and protect the heater elements. One or more heater modules thus constructed may be easily transported to a selected site.
