Data Centers

In the fast-paced world of data centers, reliability, efficiency, and security in power distribution are paramount.

The power corridors of the cables (in-door) and feeders (outdoors) demand a high degree evaluation of the external thermal environment of the system. Since the early 2000, Geotherm has been offering thermal and electrical resistivity testing services, selection of thermal backfills and designing thermal duct-bank concrete as well as low strength Fluidized Thermal Backfills (FTBTM).

Our clientele ranges from internet and telecommunication companies, software firms and electrical utilities. With a portfolio of 300+ data center projects, our extensive experience ensures reliable results for our clients. Using our proprietary thermal testing equipment and ability to deliver on time, every time.

Over the past few years, I have had the great pleasure of working with you and the Geotherm team on multiple projects. Many times, I have leaned on your deep understanding of the heat calculation/engineering process, that is critical to the success of these large scale datacenter projects. It is evident that you and the Geotherm team are on the cutting edge of this interesting cross section of applied physics, and megaproject civil & electrical engineering. Additionally, your team has always reacted swiftly to the challenging timeframe demands that these projects often entail. I also find it invaluable that your team will reach out and ask questions immediately on any missing information or clarifications that are needed, instead of waiting until the last minute or allowing deliverables to push. These projects that I’ve been involved in would not be successful without your team’s partnership on this process. I am looking forward to continuing to work closely with you and would recommend to anyone who needs highly knowledgeable, professional, responsive, services that deliver on demanding timelines.
