The THW Series is unlike any other water-to-water heat pump on the market today. The large operating map of the scroll compressor allows high temperature operation, up to 145°F [63°C] leaving load water temperature even at 32°F [0°C] entering source water temperature. The combination of a coaxial (tube-in-tube) heat exchanger for the source (ground loop) side and a brazed plate heat exchanger for the load (heating/hot water) side provides very high efficiencies. Integral controls for hydronic heating and domestic water heating avoid the need for external microprocessor-based controls for outdoor temperature reset, warm weather shutdown, staging and other controls.
Available in size 10kW [32,600 Btuh] for 60Hz voltages, and sizes 8kW, 10kW and 12kW for 50Hz voltages, the THW offers a heat pump for most any installation. The THW has an extended range refrigeration circuit, capable of ground loop (geothermal) applications as well as open loop (well water) applications. Standard features and factory-installed options are many. Unique application-specific controls make the THW Series ideal for hydronic heating and domestic hot water generation. The heating-only refrigeration circuit is optimized for high water temperatures, heating efficiencies, and capacities.
ClimateMaster’s exclusive double isolation compressor mounting system, insulated compressor enclosure, and compressor discharge muffler make the THW Series one of the quietest water-to-water heat pumps available. The attractive “Euro-style” cabinet allows the unit to fit into any decor.
