Hot Air Circulation Type Industrial Oven

The DF-KX series of China Dingfeng adopts advanced hot air circulation engineering technology. As a professional manufacturer of Hot Air Circulation Type Industrial Ovens, we have equipped our equipment with high-performance multi-blade centrifugal fans and extended shaft motors. These motors can generate unidirectional horizontal airflow, which can penetrate every layer of the tray. This design ensures excellent temperature uniformity throughout the cavity (up to 1500 mm in height) - maintaining a level of ≤±3°C, even when the load is as high as 200 kilograms. By optimizing heat transfer efficiency, this system can rapidly heat up from a cold state to 200°C within a short period of time, thereby significantly shortening the production cycle and enhancing the daily production capacity of your factory.

Unique advantages

1. Zero blind zone heating: Our multi-blade centrifugal system can eliminate stagnant air areas, ensuring that every corner can reach the uniformity standard of ±3°C.
2. Rapid heat recovery: The Hot Air Circulation Type Industrial Oven equipped with a 16.5-kilowatt heating device can achieve heat recovery almost immediately after the door is opened, maintaining process integrity in high-frequency loading scenarios.
3. Energy-saving and environmentally friendly efficiency: The combination of PID regulation and 100-millimeter insulation material can reduce energy consumption by up to 25% compared to standard circulating ovens, saving costs.

Manufacturing Process

The Hot Air Circulation Type Industrial Oven is specially designed for continuous 24/7 operation. To achieve a thermal insulation effect, we have used a 100-millimeter thick high-density ultra-fine glass wool layer and high-temperature-resistant silicone rubber sealing strips to reduce energy loss. The internal chamber is meticulously manufactured from high-quality mirror-finish stainless steel, facilitating quick disinfection and sterilization while ensuring optimal heat reflection performance. The shell is made of rust-resistant SS41 cold-rolled steel and coated with a durable powder coating.

Applying Categories

No matter whether you are involved in the production of electronics, semiconductors or precision hardware, the Hot Air Circulation Type Industrial Oven can flexibly adapt to your constantly changing workflow. In the PCBA manufacturing field, it can provide the required precise and controllable environment to achieve dehumidification and secondary adhesive curing; in the hardware and tool manufacturing field, it can provide stable constant temperature capability to execute stable quenching and aging treatment cycles. The equipped programmable 99-hour timer and optional multi-channel paperless recorder can meet the digital traceability requirements stipulated by strict quality audits in aerospace and medical equipment manufacturing.

FAQ

How does the circulation system cope with high-density loads?

Unlike vertical airflow ovens, there is a specially designed mechanism to direct heat towards the trays. Even when reaching its 200-kilogram capacity, the airflow does not get blocked by the products, thus maintaining a constant heat contact between each item.

Are the internal materials suitable for use in clean rooms?

Yes. The SUS201 mirror-finish stainless steel is made of internal material and is easy to clean. It is suitable for laboratory and electronic cleanroom environments. If there is a need for ultra-purity, we also offer customized SUS304 upgrades.

Can the temperature curve be remotely monitored for quality control?

Sure. It provides standard PID digital interface, and you can also choose to equip with a color touch screen + PLC system and "paperless recorder" configuration. This enables you to record, view and export temperature data.
