Stay cool this summer with DuroZone from Duro Dyne!

Duro Dyne offers a variety of cable operated dampers to help keep you cool all summer long.

Cable operated dampers are the most convenient and economical way to balance air flow through the face of a diffuser. The damper is installed upstream of the diffuser with the control cable outside the airstream. The air flow is adjusted by simply pushing or pulling on the core wire which changes the damper blade position. Once the adjustment has been made, it is locked by tightening the set screw nearest to the looped end.

Duro Dyne offers a variety of Fire Dampers for all your needs!

Static fire damper applications are where the HVAC systems fans are automatically shut down in the event of a fire and for use in air transfer openings in walls or partitions.

Dynamic fire damper applications are where the HVAC systems remain operational in the event of a fire.

Reduce your costing headaches with the Strut Kit Assembly from Duro Dyne!

Job costing is made easy when you can buy only what you need without having excess left over product.

The Strut Lock Assembly offers a rapid, lockable solution for HVAC and cable management, ideal for suspending various items such as ducts, cable trays, and unit heaters. With pre-fitting capabilities on the ground, it minimizes work at heights, while a threaded release cylinder allows for quick height adjustments, saving time.


Our CEO G.R. Schrotenboer and HVAC Division President John MacQuarrie recently visited our Sealed Unit Parts Co., Inc. facility in Allenwood, NJ, and Duro Dyne Corporation operations in Bay Shore, NY. During their time at each location, they engaged with employees, and most importantly, listened. They heard firsthand about the successes and challenges our teams face as they work hard to deliver exceptional results for our customers each day.

A huge shoutout to our teams in the Northeast for hosting👏 It was a great opportunity for everyone to work together on ways NSI can be the best company possible for all our stakeholders!

Duro Dyne hosted BBQ’s for employees last week at all locations.

Our Memorial Day BBQ was filled with delicious food, great company, and wonderful memories. The event was meant as a heartfelt show of appreciation to our team and we look forward to the next time we can get together for a few relaxing moments in the sun!


In honor of Military Appreciation Month, we’re highlighting a few of our people who serve, or have served, in the U.S. Armed Forces.

This is Richard Benitez, Sr. Warehouse Operations Manager for Duro Dyne Corporation. He wanted to serve his country like many of his family members did, so he joined the Army as a Specialist 5 converted to a Sergeant. He credits his time in the military with teaching him the importance of team building and working together toward a common goal, which he puts into practice each day as a leader here at NSI.

Thank you for your service, Richard!
