The drying oven uses the air blast cycle to drive the hot airflow to achieve the purpose of drying and heating, benchtop drying oven is must equipment in every laboratory, today let’s briefly introduce the structure and working principle of the NetDry drying oven:


Constant drying oven consists of a box, a temperature control system, and an air circulation system. The exterior oven is made of high-quality cold-rolled steel plate, the exterior is electrostatically sprayed, and the interior oven made of mirror stainless steel. Can effectively prevent rust, corrosion. Insulation layer for high-quality insulation cotton, the least heat loss, studio and oven door connection with high-temperature silicone sealing ring. The temperature control system is PID adaptive control mode, no temperature control parameters adjustment, high control accuracy, no overshoot. The temperature circulation system of the constant temperature drying box is composed of a heating pipe, blower, and air duct. Using the operation of the fan, the air convection is forced to improve the temperature uniformity of the studio. The position of the heating tube is generally on both sides, the rear side, and the top heating concentration, the more common small thermostatic drying box on the market is back heating.

2. Working principle

Hot air circulation oven working principle: air circulation system adopts fan circulation air supply mode, circulation is uniform and efficient. The air source is driven by the circulating air supply motor (using a contactless switch) to drive the air wheel through the heater, and the hot air is sent out, then through the air duct to the oven, and then the air suction duct after use becomes the air source for recycling and heating. Ensure interior temperature uniformity. When the temperature value swings due to the opening and closing action, the air supply circulation system quickly returns to the operating state until the set temperature value is reached.
