GTR - Gas Thermal Remediation
ISOTEC is now part of the GEO team implementing Gas Thermal Remediation (GTR) for In-Situ Thermal Desorption (ISTD), Ex-Situ Thermal Remediation, Thermal Conductive Heating (TCH), and Thermally-Enhanced Vapor Extraction (TEVES) projects in North America. GTR units heat by natural gas or propane allowing the greatest flexibility in thermal remediation while being reasonably priced compared with current thermal remediation alternatives. The systems incorporate vacuum extraction (i.e. soil vapor extraction) to recover contaminants. The technology remediates sites contaminated with BTEXs, chlorinated solvents, PAHs, PCBs, pesticides, and coal tar. The patented technologies, including the GTR and GTR+F systems, allow fully scalable In-Situ Thermal Treatments. All energy is provided by mobile propane tanks, meaning no site electrical upgrades are needed, making installations rapid and affordable. The technology can efficiently treat large projects.
