The hot air circulation oven is composed of angle steel, stainless steel plate and cold steel plate. The insulation layer is filled with high-density aluminum silicate cotton. The high-density aluminum silicate cotton ensures the thermal insulation of the drying box and also ensures the safety of the user. The heater can be installed at the bottom, top, or both sides. Use digital smart meter to control temperature. There are two types of hot air circulation oven air duct design: horizontal air supply and vertical air supply!

Product features: The shell is made of high-quality cold-rolled steel plate, and the surface is electrostatically sprayed. The appearance is novel and durable. The studio is made of high-quality stainless steel plate or cold-rolled steel plate, which has the advantages of high temperature resistance, corrosion resistance, and no black smoke. The movable pull-out net rack increases the storage space for the materials in the box. The door of the box is equipped with a double-layer tempered glass observation window, which can observe the situation of the heated objects in the working room at any time. Hot air circulation oven is a device that uses electric heating wire to heat and dry objects.

It is suitable for baking, drying, heat treatment, etc. in the range of 5 ~ 300 ℃ higher than room temperature (some 200 ℃ higher). The sensitivity is usually ± 1 ℃. There are many models, but the basic structure is similar. Generally, it consists of a box, an electric heating system and an automatic temperature control system. Its use and precautions are summarized as follows:

1. The hot air circulation oven must be placed in a dry and horizontal place in the room to prevent vibration and corrosion.

2. It is necessary to pay attention to the safe use of electricity. Install a sufficient capacity power switch blade according to the power consumption of the hot air circulation oven. Select enough power wires and have a good ground wire.

3. Mercury thermometer type thermostat with electric contact should connect the two wires of the electric contact thermometer to the two terminals on the top of the box respectively. Another ordinary mercury thermometer is inserted into the exhaust valve. (The thermometer in the exhaust valve is used to calibrate the electrical contact mercury thermometer and the actual temperature in the observation box.) Open the hole of the exhaust valve. Adjust the mercury thermometer at the electrical contact to the required temperature and tighten the screws on the steel cap to achieve the purpose of constant temperature. However, care must be taken not to rotate the indicator iron beyond the scale when adjusting.

4. When all preparations are ready, put the sample in the hot air circulation oven, and then connect and turn on the power. The red indicator light is on to indicate that the box has been heated. When the temperature reaches the controlled temperature, the red light turns off and the green light turns on, and the constant temperature starts. To prevent temperature control failures, care must also be taken.
