ClimateMaster introduced the Tranquility SL Low-Profile Series, a new generation of water-source heat pumps engineered for modern building applications. The system combines compact design, quiet operation, and energy-efficient performance to support flexible installation and simplified service.

Key features include:

  • 9" cabinet height enables installation in constrained ceiling cavities;

  • Brazed-plate heat exchanger delivers efficient heat transfer in a compact footprint;

  • Bottom-access service allows technicians to maintain all major components without removing ductwork;

  • UltraQuiet sound-attenuation package minimizes noise in occupied spaces; and

  • Double isolation compressor mounting and integrated sound attenuator box enhance acoustic performance.

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.

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.
