The hot air circulation oven is composed of angle steel, stainless steel plate and cold steel plate. The thermal insulation layer is filled with high-density aluminum silicate cotton.
The hot air circulation oven is composed of angle steel, stainless steel plate and cold steel plate. The thermal 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 the safety of users. The heater can be installed at the bottom, top or both sides. Use digital display smart meter to control temperature. There are two types of air duct designs for the hot air circulation oven: horizontal air supply and vertical air supply!
Product features: The shell is made of high-quality cold-rolled steel plate, and the surface is made of electrostatic spraying technology. It has a novel appearance, strong 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 frame increases the storage space of the materials in the box. There is a double-layer tempered glass observation window in the middle of the box door, which can observe the heated objects in the working room at any time. The hot air circulation oven is a device that uses electric heating wires to heat the object to dry the object.
It is suitable for baking, drying, heat treatment, etc. in the range of 5~300℃ higher than room temperature (200℃ higher in some cases), and the sensitivity is usually ±1℃. It has many models, but the basic structure is similar, generally composed of three parts: cabinet, electric heating system and 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 indoors to prevent vibration and corrosion.
2. Pay attention to the safe use of electricity, and install a power switch with sufficient capacity according to the power consumption of the hot air circulation oven. Choose enough power wires and have a good grounding wire.
3. The mercury thermometer type thermostat with electric contact should connect the two wires of the electric contact thermometer to the two terminal posts on the top of the box respectively. In addition, insert an ordinary mercury thermometer into the exhaust valve, (the thermometer in the exhaust valve is used to calibrate the electric contact mercury thermometer and observe the actual temperature in the box) and open the exhaust valve hole. Adjust the electric contact mercury thermometer to the required temperature and tighten the screws on the steel cap to achieve the purpose of constant temperature. But be careful not to turn the indicator iron out of the scale when adjusting.
4. When all the preparations are ready, put the sample into the hot air circulation oven, then connect and turn on the power. The red indicator light is on to indicate that the oven is heated. When the temperature reaches the controlled temperature, the red light is off and the green light is on, and the constant temperature starts. In order to prevent the temperature control from failing, it must be looked after.
