TerraTherm Gains Certification of Heating System

As an Electrical Engineer at TerraTherm, one of the most interesting (and at times challenging) aspects of my work stems from the following deceptively simple article from the National Electric Code (NEC):

Article 110.2 of the NEC
NEC 110: Requirement for Electrical Installations

The conductors and equipment required or permitted by this Code shall be acceptable only if approved.

Since the NEC is adopted, and in many instances with amendments, by individual states, this one simple article may be expanded to include additional requirements.  For example, in the California Electric Code (CEC):

CEC – Sec. 83-2 

All Electrical materials, devices, appliances and equipment shall be in conformity with the provisions of this Code, shall comply with nationally recognized standards, and shall be certified by a recognized testing laboratory as acceptable to the Chief Electrical Inspector.

In many instances, what this requirement has meant to TerraTherm was that we needed to work with an OSHA Nationally Recognized Testing Laboratory (NRTL) to perform a field evaluation of our heating system and components to the satisfaction of the Electrical Inspector/Authority Having Jurisdiction (AHJ).   This can be a time consuming and expensive process that could often lead to project delays.

In response to this costly and time consuming process, TerraTherm decided to undergo the review process required to achieve heater certification in an effort to save our clients time and money and demonstrate our continued commitment to safety. After completing rigorous testing and inspections by Intertek, one of the world’s largest Testing, Inspection and Certification companies, TerraTherm is happy to announce that we have successfully become the first thermal remediation company in the industry to gain certification of their heating system. Through Intertek, TerraTherm’s patented heater elements have obtained the Electrical Testing Labs (ETL) Mark, a symbol that verifies product compliance to applicable safety standards.

This certification process required tremendous collaborations among all of TerraTherm’s operations groups and would not have happened without everyone’s efforts.  These efforts, along with new investment in our production facilities, allowed us to go through the numerous steps of the process such as component evaluation, data collection on a functioning system and finally, an Initial Factory Assessment that gave us permission to apply the “MARK” such as the ones below:

heater cert  ul499

 

Our heating element is now a Recognized Component meeting the requirement of UL 1030 and our heating system is now certified to meet the requirement of UL499.  Intertek will be conducting unannounced quarterly inspections as part of this ongoing process.

TerraTherm’s patented heaters have been deployed throughout the world and have successfully remediated 50+ sites.  This certification demonstrates our continued commitment to safety and working with our clients and the AHJs for a speedy and efficient implementation of remediation projects.
