- Air-cooled. Does not require house or facility chilled water. Can operate in any standard room, laboratory or office.
Reliable Freon-Free Thermoelectric Technology
With lifetimes exceeding 200,000 hours, the thermoelectric modules at the core of this chiller make for high intrinsic reliability.
Optimized for Modest Heat Loads
ThermoRack's 300, 400 and 650 Watt capacities are below the economical range of refrigerant-based chillers and ideal for many laser, biomedical and industrial applications.
Because its only two moving parts are the pump and cooling fan, ThermoRack operates very quietly.
Precise Temperature Control
Because electrons transfer the heat, ThermoRack responds instantaneously to changes in load. Its digital PID temperature controller holds to ±0.05 °C, even near ambient.
ThermoRack 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 ThermoRack only draws as much power as needed. It is also designed to operate within the modules’ most energy-efficient range.
ThermoRack is virtually vibration-free when equipped with the smooth-flow magnetically coupled gear pump.
