Why choose ThermoCube 400L or 600L?

  • 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 controller holds to ±0.05°C, even near ambient
  • Optimized for Modest Heat Loads
  • Versatile: For use with fluorinert, glycol solutions or water
  • Energy Efficient: ThermoCube's thermoelectric modules are powered by variable voltage power supply that provides the 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
  • Liquid-Cooled: For use with recirculated filtered treated industrial water
  • High Pressure Pumps Standard: ThermoCube's standard pump is capable of delivering up to 50 psi for laser diode and other high-pressure applications. Low-pressure pumps are also available.
