Did you know that at Enertech we manufacture all of our geothermal systems right here in the United States? To help you get to know us better, we are giving you a behind the scenes look at our manufacturing process with our new blog series “Made in Mitchell.” For the first installment, join us for a “tour” of our sheet metal bending station; no plane ticket required!  

You’ll find our manufacturing facility in Mitchell, South Dakota right past the world’s only corn palace and endless span of rich American farmland. This is where we build incredible geothermal systems, test them, and ship them to contractors across the U.S. and Canada. It’s also where you will meet Dylan, Aaron & Riley, our dedicated employees who operate the press brake machines we use to build our geothermal system cabinets and other sheet metal components.   

A press brake, also known as a brake press, is a large machine used to bend sheet and plate material, most commonly sheet metal. It forms predetermined bends by clamping the sheet metal between a matching punch and a die. 


At Enertech, we use press brake machines to bend all of the sheet metal parts for the all new YT multi-position vertical packaged and VS/VT compact vertical packaged models, as well as the WS water-to-water models. We also produce some of the sheet metal parts for the WD dual compressor water-to-water and Cold Climate units. The use of these sophisticated machines allow us to reduce our reliance on sourcing pre-bent cabinets and structural components. 

The sheet metal is first cut to shape using a turret punch press machine. Then the operator feeds the trimmed sheet metal into the press brake and aligns it over a special die(s). The machine lowers a punch to force the metal into the die(s). This creates the first bend. The operator then repeats the process to make the other bends necessary to complete the part. 

Being able to bend our own sheet metal allows Enertech to keep costs lower for our distributor and dealer partners, without sacrificing quality. You can count on Enertech to continue to look for ways to streamline and improve our manufacturing processes to increase the reliability of our equipment, while keeping costs under control.
