Hot air circulation oven is composed of angle steel, stainless steel plate and cold steel plate. Insulation layer is filled with high-density aluminum silicate cotton, high-density aluminum silicate cotton to ensure the insulation of the oven, but also to ensure the safety of the user. The heater may be installed at the bottom, top or both sides. With a few intelligent instruments to control the temperature. Hot air circulation oven air duct design in two ways: horizontal air supply and vertical air supply!
Features: Shell made of high quality cold-rolled steel plate, the surface electrostatic spray technology, the appearance of new, durable. The studio is made of high-quality stainless steel or cold-rolled steel plate, with high temperature, corrosion resistance, no black smoke and so on. Activities of the pull-type grid, an increase of the storage space inside the box door with double tempered glass observation window, you can always observe the work of the heated objects in the situation. Hot air circulation oven is the use of heating wire insulation heating equipment to dry objects.
It is suitable for baking, drying, heat treatment and so on, the sensitivity is usually ± 1 ℃, which is higher than the room temperature 5 ~ 300 ℃ (some high 200 ℃). It's a lot of models, but the basic structure is similar to the general by the box, electric heating system and automatic temperature control system composed of three parts. Its use and precautions are summarized as follows:
1. Hot air circulation oven must be placed in the indoor dry and level, to prevent vibration and corrosion.
2. Safety of electricity should be noted that, according to the hot air circulation oven power consumption to install a sufficient capacity of the power knife. Use adequate power leads and a good grounding wire.
3. With a mercury thermometer thermostat should be electrical contact thermometer two wires were connected to the top of the two boxes on the terminal. The other will be an ordinary mercury thermometer inserted into the exhaust valve, (exhaust valve thermometer is used to proofread the mercury thermometer and observe the actual temperature inside the box) to open the exhaust valve hole. Adjust the electrical contact mercury thermometer to the required temperature after tightening the screws on the steel cap to achieve the purpose of temperature. But must pay attention to regulation when the iron will not be directed to the scale outside the scale.
4. When everything is ready to put the sample into the hot air circulation oven, and then connect and turn on the power, the red indicator light indicates that the box has been heated. When the temperature reaches the controlled temperature, the red light turns off the green light to start constant temperature. In order to prevent temperature control failure, must also look after.
