Why choose ThermoCube 200, 300 or 400?

  • Reliable, Refrigerant-Free Thermoelectric Technology: With lifetimes exceeding 200,000 hours, the thermoelectric modules at the core of this chiller make for ultra-high intrinsic reliability.
  • Compact Size: less than 13” (32 cm) on a side
  • Precise Temperature Control: ThermoCube's digital PID control holds to ±0.05 °C, even near ambient
  • Highly Customizable
  • Versatile: For use with water/glycol solutions, Fluorinert, HFE or water
  • Energy Efficient: ThermoCube's thermoelectric modules are powered by variable voltage power supply that provides minimum power required to control temperature at set point, so ThermoCube only draws as much power as needed (typically <200 W AC).
  • Whisper-Quiet: as low as 49 dBA
  • Virtually Vibration-Free
  • Worldwide Power Compatibility, Universal Input Standard
  • Easy-to-Use controller for fixed temperature control or temperature cycling
  • Air-Cooled: Does not require house or facility chilled water. Can operate in any standard room, laboratory or office.
  • Eight pump choices:  including diaphragm, magnetic gear drive and centrifugal
