ClimateMaster® introduces the Tranquility® SL Low-Profile Series, a new generation of water-source heat pumps engineered to meet modern building challenges with advanced controls, quiet performance and sustainable comfort.
With a nine-inch cabinet height, the Tranquility SL installs easily in tight ceiling spaces, giving users greater flexibility. Built for performance and ease of service, the SL heat pump model exceeds ASHRAE 90.1 efficiency standards. Its brazed-plate heat exchanger delivers efficient heat transfer in a compact footprint, while electronically commutated (EC) blower motors and integrated water control options maximize system efficiency.

For environments that demand quiet comfort, the Tranquility SL includes an UltraQuiet sound-attenuation package, double isolation compressor mounting and an integrated sound attenuator box. Powered by CXM2 communicating controls, the Tranquility SL offers real-time system diagnostics, fault memory and faster commissioning when connected to a wireless service tool.
“With the new Tranquility SL Low-Profile Series, ClimateMaster is redefining what’s possible in water-source heat pump design,” said Caleb Fox, director of product management & product support, ClimateMaster. “Engineered for modern buildings, the Tranquility SL combines advanced controls, ultra-quiet performance and sustainable efficiency, all within a compact cabinet.”
When paired with the iGate® 2 thermostat, the system provides a cloud-connected, web-enabled gateway that allows users and technicians to monitor, control, and diagnose the system from anywhere, ensuring optimal comfort and uptime. The Tranquility SL model also features an industry-first, bottom-access design that allows technicians to easily service all major components without removing any ductwork.
The Tranquility SL represents ClimateMaster’s ongoing commitment to innovation, efficiency and comfort—advancing water-source heat pump technology for the next generation of building design.
