Specification: Suitable for various industrial, laboratory and R&D applications. Double Walled Construction. Interior of the Tray Dryer is M.S / S.S-304 / SS- 316 grade Exterior of the Tray Dryer is powder coated. High Grade Mineral wool insulation is stuffed in between the formed cavity to eliminate heat losses when the oven is operated at desired temperature. Heating is through special grade tubular air heaters placed in the circulating air path. Heavy Forced Air Circulation by Strong and Reliable axial flow fans for cross flow circulation. Adjustable Damper to exhaust moist air or fumes/vapours which in turn enhances thermal efficiency MICROPROCESSOR BASED PID DIGITAL TEMPERATURE INDICATOR- CUM-CONTROLLER with an in-built DIGITAL TIMER to control the temperature from ambient +5°C to 250°C. Once the unit is switched ‘ON’ heating starts automatically and once the set/desired value is achieved the in built AUTOMATIC DIGITAL MINUTE TIMER starts automatically. Once this set time period is over the heaters are switched “OFF” automatically and the unit sounds a BUZZER, thus alerting the user that process is complete. Digital PID Control System enables superior temperature accuracy. Digital Timer function with Buzzer Alarm. Over Temperature & Over Current Protection. Voltage and Ampere meter equipped for monitoring safe operating of the machine. Brackets to support the heavily laden drying trays at adjustable height are provided on the sides of inner walls.
