Hot air circulating ovens can be divided into two types based on their air duct design: horizontal air supply and vertical air supply. Standard models mainly include single-door single-cart, two-door two-cart, two-door four-cart, three-door six-cart, and four-door eight-cart configurations. Taking the CT-C series as an example, this series all use axial flow fans, equipped with an automatic constant temperature control system, and a backup computer control system is available as an option, achieving a thermal efficiency of approximately 70%.
In addition, non-standard ovens can be customized according to user needs, including chamber size, temperature parameters, structural type (integral, modular), heating type (electric, steam, oil/gas, etc.), hot air circulation method (single circulation with lower side blowing, double circulation with top blowing, etc.), door opening method, and workpiece conveying method.
