ERH vs TCH: How to Choose Your Thermal Remediation Technology (and Why)

“How do I choose between ERH and TCH?”

It’s one of the most commonly asked questions when considering thermal remediation, and in this webinar one of the industry’s leading experts will answer it. Join TerraTherm, a Cascade Company’s Vice President John LaChance as he introduces the basic operational theory and concepts for both technologies. He’ll discuss their application to a set of typical site conditions (e.g., low and high permeability zones in unconsolidated and bedrock formations) and contaminants (e.g., CVOCs), and highlight typical design approaches, assumptions, and the pros and cons of each.

John will share real-life examples of full-scale projects involving electric resistance heating (ERH) and thermal conductive heating (TCH), including detailed breakdowns and comparisons of costs. He’ll also touch on ETDSP^TM, a form of ERH that employs active injection and extraction of water. If you have burning questions about how ERH and TCH stack up, this is your chance to get them answered.
