Nortek Global HVAC Launches New Mammoth Light Commercial Rooftop Units

New rooftop units designed for direct replacement jobs.

St. Louis, February 14, 2017 – Nortek Global HVAC introduces a new line of next-generation Mammoth light commercial packaged rooftops. They are available in 6, 7.5 and 10 tons.

These rooftop units fit directly on pre-existing curbs without the need for curb adapters, eliminating delays and saving installation time. Even gas and electric connections are in the same location as many older units, so no service reroutes are required.

“We created our rooftop products for contractors, building owners and facility managers who need low-cost, drop-in direct replacements,” says Dave Garvin, product manger at Nortek Global HVAC. “Now our customers can easily replace outdated units with a rugged and innovative design available in our Mammoth® brand.”

Quality components are factory-installed using Nortek Global HVAC Demand Flow Technology (DFT), the most advanced and flexible quality-control manufacturing process in the industry. Foam panel construction and hinged panel doors are standard. The one-inch foam panel wall construction ensures indoor air quality is fiberglass-free, which inhibits mold growth. Panel walls are easy to clean and provide a super high R-value. High-quality hinges eliminate screws on the roof and keep the access doors in place, even in high wind conditions. A quick-ship option is available out of the factory in Dyersburg, Tennessee.

“We believe the contraction quality is what makes these rooftop units a real game changer,” adds Garvin. “The many improvements we’ve made for this product line stand to make a major impact for our customers.”

At 12.7 IEER, the units meet federal minimum efficiency standards for 2018, which puts them one year ahead of many units on the market.
