Tjernlund Products was spun off as a separate company in 1973. The original manufacturing facility had 10,000 ft2 and 12 employees. Since then we have expanded our facility to 75,000 ft2 and have grown to over 50 employees. Our engineering and manufacturing departments feature the latest technology in 3D CAD design and CNC turret presses and brakes.

Tjernlund Products is still owned and managed by Emil's grandsons, Robert and Tom and Emil's great grandson Bob. Over four generations our mission has been to provide quality engineered and manufactured products that solve exhaust, ventilation and heating/cooling problems. Paramount to our success is providing the technical support necessary so that our products are easy to select and install. We are dedicated to serving your special exhaust and ventilation needs.
