Industrial Graphite Boat Curing Oven

The DF-KX291012 Industrial Graphite Boat Curing Oven provided by Dingfeng is specially designed to operate stably in strong acidic and alkaline environments. We can offer customers the most competitive factory price. Unlike ordinary industrial ovens, its entire internal cavity is made of SUS316 stainless steel and is coated with a complete PTFE (polytetrafluoroethylene) layer to resist the chemical precursors used in photovoltaic processing. To ensure the stability of performance, we have adopted SUS316# nickel-chromium heating elements and 100 mm high-density ultra-fine glass wool insulation materials.

Core Advantages

Zero-Contamination Design: Full Teflon coating and SUS316# materials prevent rust particles from settling on delicate silicon wafers.

Heavy-Duty Large Volume: The 2900x1000x1200mm chamber is specifically sized to handle bulk batches of large-scale PV graphite boats.

Rapid Thermal Recovery: The 40kW heating power ensures the oven recovers to target temperatures instantly after loading.

Performance Characteristics

The performance of the Climate Test Chamber is dependent on its ventilation conditions. To prevent minor structural defects in the silicon wafer trays, our team has developed a dual-sided horizontal hot air circulation system. Driven by multiple-blade centrifugal fans and long-axis motors, it ensures that the temperature uniformity of the entire 200-kilogram load is ≤ ±3°C, which is crucial for the uniform curing of the anti-corrosion layer on graphite boats and solar panels, effectively prolonging the service life and preventing metal contamination during the PECVD or diffusion stages.

After-sales Support

The Industrial Graphite Boat Curing Ovens delivered by Dingfeng are all brand-new and unused original products. Their materials and manufacturing strictly comply with national or industry standards, and fully support customized production according to the customer's special agreements. Within the 12-month warranty period starting from the official acceptance and qualification of the equipment, for any quality abnormalities that occur due to normal operation in accordance with the operating procedures, we promise to provide technical support within 72 hours and offer free repair or replacement services. If the damage is caused by non-normal use or force majeure, we will actively assist in the repair, and only charge for the material costs. One year after the warranty period expires, we will still provide lifetime maintenance support. At that time, only reasonable component repair costs will be charged to ensure the long-term stable operation of your equipment.

Frequently Asked Questions

1、How does the Teflon coating improve the baking effect of the graphite boat?

In the photovoltaic industry, the fully Teflon-coated surface we use can prevent these corrosive gases from damaging the interior of the oven, providing a non-stick surface and preventing chemical cross-contamination between different batches.

2、Can it be used for treatment in a nitrogen (N2) atmosphere?

OK. We have an optional nitrogen atmosphere system equipped with a dedicated flow controller. This enables you to conduct baking in an oxygen-free environment, which is crucial for preventing the oxidation of graphite materials and silicon wafers at high temperatures.

3、What temperature monitoring functions are available during quality audits?

We can equip the Thermal Shock Chamber with an online multi-channel paperless recorder. This device will record real-time temperature curves and store historical data. These data can be exported via USB for internal quality control or for client audits.
