With each passing year, rooftop system developers find new ways to improve this staple piece of HVAC commercial equipment.

“Obviously, energy conservation and energy efficiency are two huge trends in the market.”

Daikin Applied introduced two chillers and a rooftop unit and also took the opportunity to discuss the company’s decision to transition to R-32.

The biggest competitor for Green Link Eco-Engineering’s KnuckleHead line of rooftop supports is wooden blocks.

At a booth thick with traffic at the AHR Expo’s, commercial product manager Schlegel talked about Johnson Controls’ new YORK Sun Choice rooftop unit.

The YORK brand of JCI is launching a line of RTUs designed to exceed the DOE energy efficiency standards, which will take effect January 1, 2023.

These products are designed to serve both the new construction and replacement markets.

This product allows technicians to safely lift, move, and set commercial rooftop a/c units up to 27-ton capacity or 2,500 lbs.

The first phase took effect on January 1, 2018, and increased the minimum efficiency of commercial rooftop units (RTUs) by about 13 percent.

Used in new construction and retrofit applications, the product is small, light, and customizable.
