HEC and INR recirculating chillers satisfy low capacity temperature control demand in the range of 140 to 1200 watts. A refrigerant-free, thermoelectric peltier element controls temperature from 10.0 to 60.0°C, with precision of ±0.01°C under stable load conditions. Extracted heat can be air or water cooled. 15 alarms support functional troubleshooting, and can be observed on the LCD display or over serial communication. Low noise and vibration, compact dimensions and flexible power requirements are suitable for laboratory benchtop service.
