Benefits of the ThermoCube 400AC Enclosure Air Conditioner

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 AC model is available in 400 Watt capacity, for up to 150 cfm recirculating air or inert gas.

Whisper Quiet
With only one moving part, the cooling fan, ThermoCube 400AC is quiet.  Available with four fan options and sound-dampening insulation, the quietest model runs at 49 dBA.

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 is virtually vibration-free with fan as only moving part.
