It can be widely used for rapid drying of materials, testing of material heat resistance performance, etc. A high-quality oven is reflected in its short heating time to the rated temperature, short process, and uniform temperature. The inner liner of the box is made of mirror stainless steel or high-quality galvanized sheet, and the inner corner of the studio is in a circular arc shape, making the temperature inside the box more uniform. The outer shell of the box is made of high-quality cold-rolled steel plate, and the surface is sprayed with plastic for a more beautiful and innovative design. The box door is made of three- tempered glass combined with insulation fibers, embedded in the box door, allowing for clear observation of the heated items inside. The connection between the studio and the box door is equipped with a heat-resistant silicone rubber sealing ring to ensure a seal between the studio and the box door. Adopting a microcomputer PID temperature controller with temperature control protection and digital display, with timing function, the temperature control accuracy is reliable. The hot air circulation system consists of fans that can operate continuously at high temperatures and suitable air ducts, with uniform temperature inside the workshop.
