Duro Dyne adds Large Selection of Fire Dampers, Insulated Access Doors and More
Slideshow: The NSI-owned company made their new offerings a centerpiece of their booth at the 2023 AHR Expo
Duro Dyne marked their entrance into the fire damper market with a wide selection of fire, smoke and opposed blade dampers earlier this year – neatly packing the new products in one display on the 2023 AHR Expo floor.
Gina Marx from Duro Dyne says they deployed the intellectual property behind the designs in the New York market “to get things rolling. But now we’re going national.”
Duro Dyne has sold contractors round duct access, grease trap and other fabricated sheet metal doors for years now, but expanded their offerings by acquiring the rights to fire damper designs following NSI’s purchase of the company in Nov. 2021.
The HVAC mainstay Duro Dyne has since benefitted from its parent company’s robust distribution model – priming the acquisition for growth. The more than 15 new duct dampers range from static and dynamic systems to fire/smoke dampers. Duro Dyne is also offering new access doors, all from the NSI Industries website.
“We have a 4 in.-deep fire damper, we have an A style damper where the blades are in the airstream, then we have a B style damper where the blades are 100% out of the airstream, allowing for free airflow. And then we have a C-style damper, which is a square to round damper for round ducts,” Marx says. “We also have a ThinLine damper for your 2 in. ducts, where we put mounting collars on it for your registers.”
Various dampers are available at either a 1 ½ hour or 3 hour fire rating. Duro Dyne is also offering opposed and parallel blade dampers, where the standard model can include a manual hand quadrant, and the low leakage model meets AMCA Standard 500.
