Original Press Release:

New TempMaster® OmniElite(TM) Single Package Rooftop Units Deliver Comfort with Reduced Cost

MILWAUKEE  – Johnson Controls 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 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 to cut costs while improving comfort. The systems also include:

Advanced ventilation control to avoid waste of conditioning excess outside air and monitor unit functions for maximized efficiency

Airside economizer for compressor-free cooling when outdoor air is cool and dry

Variable-speed drives that slash fan-energy costs as much as 40 percent compared to inlet-guide vanes on some competitive units

Simple, intuitive controls that are standard and are factory-installed to ensure hassle-free operation

Single-point power connection that reduces field wiring costs

Optimized for HFC-410A refrigerant, the TMAL rooftop units also allow easy access to components.
