Forced-Air Drying Oven — Upgraded Generation
Product Features
- Manufactured using advanced laser and CNC processing equipment, this product is used for drying, baking, wax melting and sterilization in industrial and mining enterprises, testing laboratories and research institutions.
- The interior is made of mirror-finished stainless steel with argon-arc welding, while the exterior uses steel sheet for an attractive, modern appearance;
- A digital microcomputer P.I.D temperature controller with overtemperature-deviation protection and a timer provides precise, reliable temperature control;
- The hot-air circulation system combines a fan capable of continuous operation at high temperatures with suitable air ducts to improve chamber temperature uniformity;
- New synthetic silicone sealing strips withstand prolonged high-temperature operation, offer long service life and are easy to replace;
- Chamber air intake and exhaust volumes can be adjusted from the temperature-control panel;
- An independent temperature-limit alarm system automatically interrupts operation if the limit is exceeded, ensuring safe experiments without accidents (optional);
- An optional printer or RS485 interface connects a printer or computer to record changes in temperature parameters;
