Tranquility® 18 (SR) Versatile Single-Stage Series
The Tranquility® 18 (SR) Versatile Single-Stage Series raises the bar for water-source heat pump features and application flexibility. Not only does the Tranquility SR exceed ASHRAE 90.1 efficiency standards, but it also uses R-454B, a low Global Warming Potential (GWP) refrigerant, making it an environmentally friendly space conditioning solution.
Tranquility SR is eligible for LEED® (Leadership in Energy and Environmental Design) points due to its innovative, environmentally conscious design.
The Tranquility SR stands out for its most comprehensive set of options in a compact footprint, making it the value leader in water-source heat pump products.
