Johnson Controls Inc. has extended its TempMaster® line to include OmniElite™ single-package rooftop units. Available in 50- to 65-ton cooling capacities, the new units offer a footprint up to 20 percent 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 protect against corrosion and bacterial growth for improved air quality.
