 Solid State Cooling Systems


Why choose ThermoCube 300A?

  • 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: Digital PID control holds to ±0.2 °C, even near ambient 
  • Optimized for Modest Heat Loads
  • Versatile: For use with CDA, N2, argon or other compressed, inert gases 
  • 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) 
  • 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.
