Model RT rooftop units are designed for mixed air applications.

Greenheck’s Model RT line of rooftop units are designed for mixed air applications, bridging the gap between traditional rooftop ventilators and dedicated outdoor air systems. The units simultaneously control both temperature and humidity to optimize indoor comfort.

Energy-efficient features include inverter scroll compressors, which modulate to deliver precise cooling and dehumidification while improving part-load efficiency. Direct drive supply and exhaust fans offer a wide performance range and standard modulation capabilities for variable air volume (VAV) systems. Condenser fans feature electronically commutated (EC) motors that modulate to control head pressure and improve efficiency. Choose from two cabinet sizes: RT-70, with airflow from 2,000 to 7,900 cfm, and RT-120 (pictured), with airflow from 3,500 to 13,000 cfm.
