The Tranquility® TRL Series introduces the next generation in technology of commercial water source heat pumps. Its unmatched low-profile height allows it to be installed in ceiling spaces as low as 12” in height. This space saving solution gives architects greater freedom when designing buildings. When compared to other horizontal water source heat pumps on the market, the TRL series allows building owners the ability to reduce floor to floor slab height saving money in construction materials.

Tranquility TRL products offer integrated water control options that save system watts by preventing over pumping both when the unit is in operation and when its not. ECM fan motors maximize the systems airflow movement efficiency. Advanced communicating controls offer reduced startup and commissioning time by providing an easy to read gateway into the system operating conditions. The low-profile product series design is paired with industry exclusive serviceability features along with many options for increased application flexibility and system efficiency.
