The explosion-proof forced-air drying oven is a highly reliable heat treatment equipment designed specifically for high-risk working conditions. It integrates explosion-proof technology, precise temperature control, and a forced convection circulation system, providing safety assurance for industrial production and material heat treatment. The oven body features a steel plate and multiple explosion-proof structural designs. The circulation fan, driven by a high-efficiency explosion-proof motor, creates a uniform and stable hot air flow inside the chamber, ensuring temperature field consistency and completely eliminating the possibility of electrostatic discharge and contact with flammable gases, thus preventing explosion risks at the source. It is primarily used in industries such as petrochemicals, military and nuclear industries, aerospace, pharmaceuticals, and paints and coatings.

① Color LCD Screen Controller: Equipped with a color screen and touch buttons, displaying parameters such as set temperature, operating temperature, constant temperature time, and fault information on a single screen; integrates a microprocessor intelligent temperature control system with dynamic PID parameter adjustment, offering fast response speed and temperature overshoot suppression;
② Multiple Timing Modes: 1. Timing units can be freely switched between minutes and hours; 2. Two timing modes: timing starts upon power-on and timing starts after reaching the constant temperature;
③ Upgraded sound and light alarm environmental scanning microcomputer chip with stable data processing capabilities;
④ Features include over-temperature alarm, over-temperature heating cutoff, timed shutdown, power-on recovery, parameter memory, temperature correction, and self-tuning;
⑤ Power Failure Recovery Function: After a sudden power outage and subsequent power restoration, the device can automatically resume operation according to the original settings;
⑥ Self-tuning: When the temperature control accuracy is affected by changes in ambient temperature, self-tuning can be performed to improve temperature accuracy;
⑦ Multiple Modes: Switching between fixed-value mode, timed mode, and long-term mode.
