Modern Equipment & Technology
In 2018 we expanded our capabilities with a brand-new, 60,000-square-foot fabrication shop. The new facility includes a 20' coil-fed CNC plasma cutter, a 6-cradle coil line with lining capability, a waterjet cutter for HVAC duct liner and a spiral duct forming machine.
The new facility has allowed us to automate fabrication and speed up production time. For example, the coil line is three times faster than standard ductwork production. We can also run the coil line and waterjet in tandem to product ductwork and insulation at the same time, dramatically speeding up the production process.
Traditional Metal Fab Shop
At Hennemuth, we will never forget our roots. Our new facility includes a complete manual fabrication shop, where custom pieces can be formed by hand, the old-fashioned way.
We brought over the old hand shop and recreated it right in the middle of the new facility. Between the new equipment, hand shop and our expanded inventory of stock duct, GRDs, tools and accessories, we are your one-stop shop for HVAC ductwork and supplies.
Their duct work is always spot on. It's second to none. They are by far the best. Everything always fits the first time. And when I'm ordering, they understand what I'm asking for and catch my mistakes. They make me look like I'm a genius. The end result makes me really look like I know what I'm doing.
