Drying ovens generally refer to common products like blast drying ovens and vacuum drying ovens used in daily life. Aging test chambers mainly include temperature aging, sunlight irradiation aging, load aging, etc., among which high-temperature aging test chambers are the most common. Many enterprises and research institutions face difficulty choosing between drying ovens and high-temperature aging test chambers. Understanding the differences between drying ovens and aging test chambers can help accurately identify true needs and meet testing requirements.


I. Configuration Differences:
1.  Drying ovens generally do not contain turntables, whereas high-temperature aging test chambers are equipped with sample racks and turntable devices.
2.  Gas circulation control differs. The air exchange volume and frequency inside drying ovens cannot be specifically controlled and coordinated. In contrast, air exchange aging test chambers allow precise control over air exchange volume and frequency, increasing heating power and maintaining constant temperature control after air exchange.


II. Temperature Control Differences:
Regarding temperature control accuracy, drying ovens typically have a uniformity of ≤±2.5%, while thermal aging test chambers have a temperature uniformity of ≤±2℃, far superior to blast drying ovens.


III. Application Field Differences:
Blast drying ovens, vacuum drying ovens, and similar series are suitable for drying, anti-aging, baking, and sterilization of non-volatile items in industrial enterprises, schools, medical institutions, and research units, widely used in the electronics and chemical industries. Aging test chambers are primarily used for thermal oxygen aging tests on rubber, plastic products, electrical insulation materials, and other materials, or air exchange aging tests on electronic components and plasticized products.


Summary: Air exchange thermal aging test chambers are specifically designed for thermal aging tests, offering greater professionalism and test accuracy. For aging tests that do not require high temperature uniformity, air exchange, or turntables, a blast drying oven can serve as the heating platform.
