Benefits of the ThermoCube PAO Recirculating Chiller
Reliable Freon-Free Thermoelectric Technology
The ThermoCube uses thermoelectric technology, widely used throughout the world for 50 years in various applications from spacecrafts to home appliances. With lifetimes exceeding 200,000 hours, the thermoelectric modules at the core of this chiller make for ultra-high intrinsic reliability.
Optimized for Modest Heat Loads
ThermoCube PAO is available in a 275 Watt capacity, below the economical range of refrigerant-based chillers.
Whisper Quiet
With only two moving parts, the pump and cooling fan, ThermoCube is quiet.
Precise Temperature Control
Because electrons transfer the heat, ThermoCube responds instantaneously to changes in load. The digital PID temperature controller holds to < + 0.05 °C, even near ambient.
Energy Efficiency
ThermoCube is very energy-efficient. Its thermoelectric modules are powered by a variable voltage power supply that provides the minimum power required to control the temperature at set point, so ThermoCube only draws as much power as needed. It was also designed to operate in the modules’ most energy-efficient range.
No Vibration
ThermoCube provides virtually vibration-free liquid flow when equipped with smooth-flow gear or centrifugal pumps and external filter.
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.
Leak Free
Designed with all stainless steel tank, tubing and fittings
A ThermoCube 300 is shown with a regulation-size soccer ball for comparison.
All ThermoCubes are the same size.
ThermoCube Front User Interface Panel
ThermocCube PAO is only available with the 1 lpm or 2 lpm gear pumps. The remaining pumps are not compatible for use with PAO.
