About Nexjen Technologies

Our story begins in the small town of Oberlin, Ohio, where two best friends, Robert Kretchmar and Mark Fridenstine, shared more than just a childhood — they shared a vision. That vision would eventually become the foundation of our company.

After pursuing their respective degrees — Robert in Chemical Engineering from Auburn University, and Mark Fridenstine from The Ohio State University — the two reunited with an amazing idea, created by Robert.

After nearly 10 years of being an engineer in the metalworking industry, Robert generated the idea for the C-Thru Separator, a product that would go on to revolutionize how our customers manage and visualize fluid separation processes. What began as a single innovative product has grown into a full line of industrial solutions, continuously refined and improved through two decades of hands-on experience, customer feedback, and engineering excellence.

Now, with over 20 years in business, our company remains rooted in the same values it was founded on: trust, transparency, and a relentless drive to innovate. From the C-Thru Separator to our expanded lineup of industrial technologies, we’re proud to support operations across a wide range of industries with products that are built to perform — and built to last.

At the heart of everything we do is the same friendship and passion that started it all.
