Hot Air Circulation Oven with 6 Key Structural Features

The hot air circulation oven is designed with an advanced air circulation system that ensures even and efficient heat distribution. This system uses a fan-driven approach to circulate air throughout the chamber, maintaining consistent temperatures and improving overall performance.

The system is powered by a circulating motor equipped with a non-contact switch, which drives a fan wheel through the heater. As the heater warms the air, it is directed out of the oven and into the air chamber via designated passages. The used air is then drawn back in through the same channels, creating a continuous cycle that enhances heating efficiency.

This design helps maintain stable indoor temperatures, even when the door is opened or closed. If temperature fluctuations occur due to such actions, the circulation system quickly adjusts and restores the set temperature, ensuring minimal downtime.



1. **Heating System**: Features a fully independent system with nickel-chromium alloy electric heaters for reliable and consistent heat generation.
2. **Circulation System**: Equipped with a high-temperature, low-noise motor and a multi-blade centrifugal fan wheel, ensuring smooth and quiet operation.
3. **Control System**: Uses an imported advanced temperature controller with PID regulation and fast self-tuning capabilities. It allows users to set various parameters, with digital display for easy reading.
4. **Air Inlet/Outlet Function**: Includes a manual adjustment knob for airflow control and offers a timing function for convenience.
5. **Fast Temperature Recovery**: Designed to return to the desired temperature quickly after any disturbances.
6. **Safety Protection**: Offers multiple safety features, including leakage protection, short-circuit protection, over-temperature protection, motor overheating protection, and over-current protection.
