TEMPO make a tray dryer are with the forced air circulation provided by means of motorized blower fitted on the oven for recirculation of air which ensures a homogeneous hot air mixture and an exact temperature profile. Temperature range 50C to 200C Temperature accuracy ±0.1C Supply 440V, three phase Controlling System : Microprocessors based auto tune PID temperature controller with & dual display of set value & process value for precise control of temperature with PT 100 sensor is used for temperature. Heating System : SS tubular heating elements used on the side walls to maintain a uniform temperature condition inside the chamber. Air Circulation : The motorized blower fitted on the top side of the chamber develop unique airflow system which ensures maximum temperature distribution inside the temperature. The unique airflow assures that there is a quick recovery after the doors are opened.
