The TMW large water-to-water series geothermal heat pumps are available in sizes 360 (30 tons), and 600 (50 tons). The series offers high efficiency with advanced features and application flexibility. As the manufacturer’s most adaptable EarthPure® HFC-410A refrigerant units, the TMW Series can be used for radiant floor heating, snow/ice melt, chilled water for fan coils, hot/chilled water for make-up air, and many other types of HVAC applications. The TMW 360-600 has advanced digital controls for BAS interface, four LEDS for unit status, and compressor isolation switches. Other features include front and back service access panels, which allow for side-by-side installation; larger capacity, which requires fewer units per job site, staggered top water connections for ease of manifolding multiple units; and direct digital controls (DDC), which provide 11 safety protections for the refrigeration circuits.
