    Peltier element is a semiconductor device including serially connected P-N junctions. Usually these elements are powered with 12 V direct current (DC).
    When this voltage is applied, one side of peltier element is heated while the other side gets cooled. If the voltage polarity is changed, the heating/cooling property of the faces reverses. If voltage is applied to bare peltier element directly, it will instantly transfer heat from one side to another and this excess heat will cause the device burn if it is not withdrawn adequately. To do this, the peltier element must be installed such that at least one side is in contact with a heatsink including a fan attached. Our company sells all variety of peltier elements, fans, heatsinks and developes the peltier modules at desired power. These modules can be controlled by simple on off control or PID control when microcontroller is utilized. Microprocessor-controlled heater cooler we develope includes Run/Set button as well as T+ and t- buttons. Starting from ambient temperature, the cabinet can be kept at a specific temperature by continuously measuring interior temperature and employing a controlling algorithm running in microcontroller. The microcontroller is connected to relays, fans and mosfets by means of optocouplers so that no interference can reach microcontroller thus producing extremely long lifetimes. Controlled temperature range varies according to the ambient temperatures. On-off temperature control produces 0.2 °C accuracy while microcontrolled PID control achieves to 0.01 °C accuracy. The heater/cooler cabinet can be produced at any size and at any power.
