As a special cold source, TEC module has the following advantages and characteristics: no need for any refrigerant, continuous working, no pollution, no rotating parts or rotating effect. It is a solid device without sliding parts, or vibration and noise during operation, long life, easy to install.
TEC module has two functions: cooling and heating. The cooling efficiency is generally not high, but the heating efficiency is high, always greater than 1. Therefore, a single device can replace discrete heating and cooling systems. The TEC module is a current-exchangeable device. It can achieve high-precision temperature control by input current control. With the help of temperature detection and control, it is easy to realize remote control, program control and computer control, and it is easy to form an automatic control system. The thermal inertia of the TEC module is very small, the cooling and heating time is very fast. When the hot side is cooled well and the cold side has no load, the cooler can reach the maximum temperature difference in less than one minute.
The TEC module has many applications. One of them is to keep the diode laser chip working at a constant temperature, so the laser will be a bunch of laser output wavelength stable, constant power, low optical noise.
ATI develops multiple series of TEC modules, with different currents, voltages, and powers. You can refer to our website for more details:
