Overview

Why choose ThermoCube PAO?

  • Leak free:  built with all stainless steel tank, tubing and fittings
  • 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 PAO's digital PID control holds to +0.1 °C, even near ambient. 
  • Optimized for modest heat loads: Cooling capacity up to 275 Watts 
  • 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 
  • Air-cooled: Does not require house or facility chilled water. Can operate in any standard room or lab.
  • Three pumps types are available.  The standard pump is capable of delivering up to 45 psi for avionics and other high-pressure applications.
