Hot air oven
This is a double-walled oven with the inner chamber made of aluminum or stainless steel sheet and the outer surface of mild steel sheet with a gap of 64 mm between walls filled with glass wool for proper insulation to avoid heat loss. Outside is finished in durable white enamel. Two or three removable shelves are provided in the inner chamber. The door is fitted with heavy cast chromium-plated hinges and a spring-type automatic roller to and fro latch.
The temperature is controlled with a precision thermostat. The inner chamber is heated with the help of coil heaters placed at the bottom with a three-point control switch (Rotary Switch) for low, medium, and high wattage.
The temperature control knob is graduated. The wattage control knob is marked OFF, LOW, MEDIUM, and HIGH. The control panel is mounted directly below the door. The neon pilot lights are provided which indicate control cycles as well as mains.
Complete with adjustable shutters for ventilation near the top, shelves, wire, and plug but without a thermometer. Suitable for operation on 220 V, 50 Hz, single-phase supply.
