Application Examples Principle of Peltier Device (Thermo-module, Thermoelectric device) Features Circulating pump Peltier element (Thermo-module, Thermoelectric device) Temperature sensor . Accurate display by measuring the circulating fluid with a temperature sensor directly Exclusively developed dual tank construction to provide consistent temperature at any position in the bath Semiconductor Various tests Physical and chemical analysis Various chemical processes Evaporation of chemicals for MOCVD Temperature control of diffusion gas Thermal test with immersion Temperature control of various samples, materials and parts Indirect temperature control of chemicals and liquids with high viscosity A Peltier device (thermo-module, thermoelectric device) is a plate type element, inside which P-type semiconductors and N-type semiconductors are located alternately. If direct current is supplied to the Peltier device, heat is transferred inside the device, and one face generates heat and increases temperature while the other face sucked heat and decreases temperature. Therefore, changing the direction of the current supplied to the Peltier device can achieve heating and cooling operation. This method has a fast response and can shift quickly between heating and cooling, so temperature can be controlled very precisely.
