Essential Conditions for Safe Operation of a Hot Air Circulation Oven

The hot air circulation oven is constructed with angle steel, stainless steel plates, and cold steel plates. The insulation layer is filled with high-density silica-alumina wool, ensuring the oven's thermal insulation properties and user safety. The heater can be installed at the bottom, top, or sides. A digital intelligent instrument is used to control the temperature. The design of the air ducts in the hot air circulation oven comes in two types: horizontal air supply and vertical air supply!

　　Product Features:The casing is made of high-quality cold-rolled steel plates, featuring a static powder coating process for a novel appearance and durability. The studio is constructed from superior stainless steel or cold-rolled steel plates, offering benefits such as high-temperature resistance, corrosion resistance, and smokeless operation. The retractable mesh frame increases the storage space inside the box. The middle of the box door is equipped with a double-layer tempered glass observation window, allowing for real-time observation of the heated items inside the studio. The hot air circulation oven is a device that uses an electric heating wire mesh to heat and dry objects.

It is suitable for baking, drying, and heat treatment within a temperature range of 5~300℃ above room temperature (some models up to 200℃ higher). Its sensitivity is typically ±1℃. There are many models available, but they share a similar basic structure, generally consisting of a housing, an electric heating system, and an automatic temperature control system.Summary of usage and precautions follows:

The hot air circulation oven must be placed in a dry and level indoor location to prevent vibration and corrosion.

2. Ensure safe electrical usage by installing a power switch with sufficient capacity based on the power consumption of the hot air circulation oven. Use adequate power cables and ensure a good grounding wire.

3. With electrical contact pointsWater YinThermometer-style temperature controllers should connect the two wires of the electrical contact thermometer to the two terminals at the top of the box separately. Additionally, insert a standard water thermometer into the exhaust valve, as the thermometer in the exhaust valve is used for calibrating the electrical contact thermometer.Water YinOpen the exhaust valve hole for the thermometer and observation box (used for measuring the actual temperature inside). Adjust the electrical contact point.Water YinOnce the thermometer reaches the desired temperature, tighten the screw on the steel cap to maintain a constant temperature. However, be cautious not to rotate the indicator iron beyond the scale when adjusting.

4. Once all preparations are complete, place the sample into the hot air circulating oven, then connect and turn on the power. The red indicator light illuminates, indicating the oven is heated. When the temperature reaches the set temperature, the red light turns off and the green light comes on, initiating the constant temperature mode. To prevent temperature control failure, constant monitoring is required.
