ClimateMaster® announces the addition of hot gas reheat to its Tranquility® SB compact high-capacity series, further enhancing the platform’s ability to deliver precise humidity control, improved occupant comfort, and energy-efficient performance in demanding applications.

The new hot gas reheat option allows the Tranquility SB to effectively manage latent loads without overcooling occupied spaces, making it ideal for schools, healthcare facilities, multifamily buildings, and other humidity-sensitive environments. By reheating air using recovered heat from the refrigeration cycle, the system improves moisture removal while minimizing energy consumption. Additionally, the standard vFlow® modulating water valve maintains head pressure for enhanced reheat capacity on colder building loops.

Exceeding ASHRAE 90.1 efficiency requirements and operating with low-GWP R-454B refrigerant, the Tranquility SB Series continues to offer a high-capacity, environmentally responsible solution for modern water-source heat pump applications. Units are available in 6- to 25-ton capacities and feature a compact vertical cabinet that fits through standard doorways, along with backward compatibility with legacy equipment to simplify retrofit installations.

Engineered for geothermal, groundwater and boiler-tower systems, the Tranquility SB includes dual refrigeration circuits, microprocessor controls, a galvanized-steel cabinet, variable-speed EC plenum fans, and an epoxy-coated drain pan to ensure long-term durability and reliable operation.

The Tranquility SB also features ClimateMaster’s iGate® 2 technology, providing real-time system visibility for technicians and owners through cloud-based monitoring, a Wi-Fi touchscreen thermostat or a wireless service tool. Additional features include extended range operation, stainless steel drain pans, DDC building interface, and the UltraQuiet™ package for sound-sensitive installations.
