Overview

The Tranquility® (TRT) Two-Stage Rooftop Series by ClimateMaster features advanced energy efficiency with models ranging from 3 tons (TRT036) to 6 tons (TRT072). Utilizing Copeland Scroll Two-Stage compressors and variable frequency drive (VFD) fan motor controls, these units can operate at as low as 60% of their rated full load capacity, ensuring a consistent leaving air temperature even with fluctuating demand. The series is equipped with intelligent iGate 2 controls for streamlined startup, commissioning, and troubleshooting, while exceeding ASHRAE 90.1 efficiency standards. Standard features include a robust galvanized steel double wall construction, multiple safety mechanisms, and options for remote monitoring and diagnostics through the myUplink mobile app. Configurable options enhance the system's Tranquility TRT to meet diverse application needs, making it a leading choice in rooftop water-source heat pumps.
