GTI Companies, Inc.

Scope Of Work

GTI specializes in high-quality, scalable geothermal (ground-source) heating and cooling for any application.

We have installed more than 85 commercial geothermal systems in configurations including pond loops, horizontal slinky systems, and vertical well systems that have ranged from 30 to 1,100 tons.

These photos show a project GTI completed for the Stearns County Service Center in Waite Park, Minnesota. This project involved one of the largest horizontal closed-loop "slinky" systems in the Midwest, which included over 100,000 feet (nearly 19 miles!) of piping below the water table.
