New Rooftop Units from Greenheck Deliver Optimized Comfort

Greenheck’s new line of rooftop units, designed for mixed air applications, bridges the gap between traditional rooftop ventilators and dedicated outdoor air systems. Model RT, simultaneously controls both temperature and humidity to optimize indoor comfort. Energy-efficient features include inverter scroll compressors that modulate to deliver precise cooling and dehumidification performance while improving part-load efficiency.

Direct drive supply and exhaust fans offer a wide performance range and standard modulation capabilities for variable air volume systems. Electronically commutated motors on condenser fans modulate to control head pressure and improve efficiency. Factory-programmed controls simplify start-up, allowing for easy field adjustment and flexible unit operation in various applications.

The RT’s cabinet features a pre-painted exterior and double-wall construction with injected foam insulation to minimize sound transmission and air leakage. Available options to meet project needs include air-source heat pumps (up to 30 tons) for all-electric cooling and heating; modulating hot gas reheat for optimal comfort without overcooling; modulating powered exhaust to maintain space pressure and modulating gas furnaces for tighter temperature control while heating.
