The HEF compact chiller use a Peltier thermoelectric device, rather than a refrigeration circuit, to extract heat from the cooling loop.  This 220W capacity chiller has a next-generation design with a footprint 80% smaller than the HEC-A chiller with similar capacity.  Volume is 87% less, and weight is 75% lighter as well.  With its compact size and 37~60 dBA low-noise operation, its presence is non-intrusive and compatible in any lab space.  The chiller is self-contained with Peltier regulation, fan cooled heat exchanger, pump, coolant tank and power supply.  The dustproof filter is replaceable. The user interface includes a 2-line display for settings and operational data.  4 input buttons allow access to set points and data screens.
