ClimateMaster introduces the Tranquility modular water-to-water heat pump series in 360 (30-ton) and 600 (50-ton) sizes. As ClimateMaster’s most adaptable EarthPure HFC410A refrigerant units, the TMW series can be used for radiant floor heating, snow/ice melt, chilled water for fan coils, hot/chilled water for makeup air and many other types of HVAC applications. The TMW 360 and 600 sizes have advanced digital controls for BAS interface, four LEDs for unit status and compressor isolation switches. Other features include: front and back service access panels allowing for side-by-side installation; a larger capacity that requires fewer units per jobsite; staggered top water connections for ease of manifolding multiple units; and DDC controls with 11 safety protections for refrigeration circuits.
