Low Energy Consumption Graphite Heater For PV Furnace

This product is made of high-purity graphite substrate through refined isostatic pressing technology. The optimized conductive heating structure design ensures uniform heating without any local high-temperature points. The material has stable resistivity and high electrical energy-to-heat conversion rate. It can operate stably at high temperatures in vacuum and inert gas environments. Through precise slotting, edge cutting, and hole drilling processes, it is suitable for various PV furnace installation structures. Customized specifications of sheet, tube, and ring heaters can be provided according to the equipment power. Surface anti-oxidation strengthening treatment is also supported.

1. Low-resistance energy-saving formula, with high thermal conversion efficiency, significantly reducing energy consumption under the same temperature field.
2. Uniform heat generation throughout the area, with small temperature difference, avoiding color differences and performance deviations in the thermal treatment of photovoltaic silicon wafers.
3. Resistant to high-temperature thermal shock, without deformation, cracking or power attenuation during frequent start-stop operations.
4. Stable chemical properties, no impurity precipitation or contamination of photovoltaic components under vacuum and high-temperature conditions.
5. Strong structural adaptability, customizable for special shapes as needed, suitable for the renovation and upgrading of new and old PV furnaces.

Traditional metal heating elements have high heat loss, slow heating speed, and are prone to oxidation and aging at high temperatures. The photovoltaic mass production process has high power consumption and unstable temperature fields. This low-energy consumption graphite heater has balanced resistance parameters, fast heating speed, and good heat preservation performance, resulting in lower energy consumption during long-term operation. It is resistant to high temperatures without oxidation and does not release metals, significantly reducing the frequency of equipment downtime and maintenance, improving the yield and production efficiency of the photovoltaic production line, and is suitable for long-term continuous production conditions.

Our factory specializes in custom production of photovoltaic energy-saving graphite heating elements. We optimize the material formula and heating structure to address the energy consumption issues of PV furnaces. We complete the entire process independently, including purification, precise processing, and performance testing. We strictly control resistivity, temperature field uniformity, and energy-saving indicators. We offer both standard parts in stock and non-standard customization. We can also cooperate with customers for energy-saving renovations of old equipment and the production of new equipment. We provide complete factory test data and foreign trade qualification documents.
