Johnson Controls has extended its TempMaster® line to include OmniElite™ single package rooftop units. Available in 50- to 65-ton cooling capacities, the company says its new units offer a footprint up to 20%smaller than competing units, double-wall construction, single-point power connection and efficiency ratings that exceed ASHRAE 90.1 standards.

Double-wall construction, which includes the roof, floor, doors and walls, helps prevent insulation fibers from entering the conditioned air and facilitates periodic cleaning of the unit to prevent harmful buildup of bacteria or contaminants. Double-sloped drain pans also protect against corrosion and bacterial growth for improved air quality.

The new TempMaster units feature multi-step capacity control, high-efficiency scroll compressors, and fully modulating gas heat in an effort to cut costs while improving comfort. The company claims the systems also includes advanced ventilation control, airside economizer, variable-speed drives, intuitive controls, and a single-point power connection.
