Tranquility® 24 (SZ) Versatile Two-Stage Series
The Tranquility® 24 (SZ) Versatile Two-Stage Series showcases superb efficiency ratings, quiet operation, and application flexibility that is synonymous with the ClimateMaster Tranquility family.
The Tranquility SZ surpasses ASHRAE 90.1 efficiency standards and uses R-454B, a low Global Warming Potential (GWP) refrigerant, setting a high standard for eco-friendly performance.
Due to its innovative, environmentally conscious design, the Tranquility SZ qualifies for LEED® (Leadership in Energy and Environmental Design) points.
