Dec. 2, 2025

Designed for mixed air applications, Greenheck’s Model RT bridges the gap between traditional rooftop ventilators and dedicated outdoor air systems. It simultaneously controls temperature and humidity to deliver optimized comfort without oversizing or overdesigning the system.

Model RT units feature inverter scroll compressors that provide efficient operation at part-load conditions, as well as electronically commutated (EC) fan motors that modulate to control head pressure and improve efficiency. Factory-programmed controls simplify startup and allow for easy field adjustment, while direct drive fans offer a wide performance range and standard modulation capabilities for VAV systems. Model RT uses the environmentally friendly R-454B refrigerant, which meets new EPA standards and reduces the system’s carbon impact.

This product is a 2025 Product Innovation Award winner.

Judge’s Comment: “Good to see Greenheck continuing their high standards in the industry.”
