GeoCube customers should update to the latest TC Module in GLD. Features include improved column recognition; automatic sensor pair selection.

Works with Windows 10 / Windows 11.

This is a free upgrade for all GeoCube owners!

02/2021
There is a new "Booster Pump" option for high-head or high flow testing for extended depth models of the GC3 GeoCube. This is an external booster that can be used for special situations which require higher flows through the test loop..

What is a TC / TRT Test?

Thermal Conductivity / Thermal Response testing is a quantitative technique for calculating the soil thermal properties necessary for designing an efficient ground source heat pump system. Typically, they are performed when designing vertical heat exchangers for commercial geothermal projects.

With the right equipment and software data analysis tools, TC/TRT tests are straight-forward to perform. A TC/TRT test provides invaluable information to accurately and economically design a loopfield.

A commercial design without accurate TC/TRT data runs the risk of being over/undersized. Can you afford to drill an extra few thousand feet because your design did not have accurate TC/TRT information for design calculations? A GeoCube can often pay for itself after only a few uses.
