When 143 years of combined company history come together, you can expect the markets to notice.


In an ever-evolving market place, the leaders of two of the oldest sales engineering firms in the business saw an opportunity to fill a need. Our goal is simple: to provide customers a singular place to solve all of their dry bulk storage, handling, & processing needs.


With the merger of The Tennant Company and SPECS completed in October of 2019, the new company formation is now capable of providing a more economical, thorough, and durable solution than ever before.


Capital equipment, equipment & process integration, process studies, spare parts, retrofits and much more. From equipment selection to installation, we have all the tools at our disposal to be able to take our customers by the hand and remove all the guess work from capital projects and efficiency updates.
