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, and the high density aluminum silicate cotton ensures the heat preservation of the drying box and ensures the safety of the user. Heater installation location is bottom, top or side. Use digital display to control the temperature. There are two kinds of air duct design for hot air circulation oven: horizontal air supply and vertical air supply.

Features of the product: the shell is made of high quality cold rolled steel sheet, the surface is made of electrostatic spray technology, the appearance is novel and durable. The studio is made of high quality stainless steel plate or cold-rolled steel plate. It has the advantages of high temperature resistance, corrosion resistance and no black smoke. The movable drawing type net frame increases the double toughened glass observation window in the middle of the storage space of the box, and can observe the situation of the heated articles in the studio at any time. Hot air circulation oven is a device that uses electric heating wire to heat the object.

It is suitable for baking, drying and heat treatment at room temperature higher than 5~300 C (some 200 degrees high), and its sensitivity is usually 1. It has many models, but the basic structure is similar. It is generally composed of three parts: the box, the electric heating system and the automatic temperature control system. Its use and attention are summarized as follows:

1. hot air circulation oven must be placed indoors dry and horizontal to prevent vibration and corrosion.

2.. Attention should be paid to the safe use of electricity. According to the power consumption of hot air circulation oven, a sufficient power knife is installed. Choose enough power supply wire and have a good grounding wire.

3.. The mercury thermometer type thermostat with electric contacts shall connect the two wires of the electrical contact thermometer to the two terminals of the box top. An ordinary mercury thermometer is also inserted into the exhaust valve. (the thermometer in the exhaust valve is used to check the electric contact mercury thermometer and observe the actual temperature in the box) to open the vent valve hole. Adjust the electric contacts mercury thermometer to the required temperature and tighten the screws on the steel cap to achieve the purpose of constant temperature. However, attention must be paid not to turn the indicator iron to the scale.

4. when all the preparations are ready, the test products can be put in the hot air circulation oven, then connect and open the power supply. The red indicator light indicates that the box has been heated. When the temperature reaches the controlled temperature, the red light goes out and the green light starts to start constant temperature. In order to prevent the failure of temperature control, it is necessary to take care of it.
