Bosch Thermotechnology has released a series of ultra-quiet heat pumps, the QV Series, for commercial spaces in multiple sizes and both horizontal and vertical configurations. The QV Series of heat pumps are Florida Heat Pump (FHP) geothermal systems that feature a compact cabinet ideal for small spaces.
The Constant Air Flow ECM DEC Star Blower produces the same cubic feet per minute of airflow as the Bosch LV model, but at a lower RPM, resulting in lower power consumption and less sound. Insulation around the blower and installed in the lower compartment further dampens sound.
