Overview
The Tranquility® 22 (TZ) Versatile Two-Stage Series is designed for high efficiency and application flexibility, featuring models ranging from 024 (2 tons) to 060 (5 tons). This series exceeds ASHRAE 90.1 efficiency standards and incorporates advanced communicating DXM2.5 controls, which streamline start-up and service processes. It boasts intelligent variable speed ECM fan motors for precise airflow control, a non-corrosive polymer drain pan, and a unique double isolation compressor mounting for quiet operation. Configurable options include internally mounted variable speed water pumps, modulating water valves, and iGate 2 thermostats for remote diagnostics. The Tranquility TZ series is ideal for tight spaces and retrofit applications, making it a choice for geothermal heating and cooling solutions.
