The ceramic fiber heaters from Teitokusha are manufactured by combining our unique heating element processing technology, ceramics technology that leverages know-how from 100 years of refractory brick manufacturing, and processing technology for ceramic fiber boards. 【Heating Element】 We primarily use round wire coil heating elements that are wound into a coil shape. Our company processes strip-shaped heating elements with slits, adjusting the slit width to design them according to the customer's requirements for current and voltage. 【Ceramics】 The essential function required for ceramics used in heaters is thermal shock resistance. Since the heating element becomes hot immediately upon applying electricity, ceramics that can withstand this rapid temperature change are necessary. We design and manufacture ceramics in-house with formulations tailored to the usage conditions. 【Ceramic Fiber Board Processing Technology】 We perform processing of heaters to the dimensions and shapes requested by our customers. Instead of leaving the ceramic fiber board as is, we also accept various processing treatments such as surface effect treatment, binder removal, and lamination. We will solve your problems with products that combine these technologies!

Examples of Solutions for Customer Concerns ■ I want to increase the electrical capacity with the same installation area. → By using a strip heater, you can achieve double the capacity in the same area compared to round wire coil heaters. ■ I want to extend the product lifespan of the heater. → A safety design calculated for the power load on the heating element makes it less likely to break. ■ I want to shorten the heating ramp-up time and heating duration. → Strip heaters have better radiation efficiency than round wire coil heaters, allowing for faster heating speeds and reduced heating time, which also puts less strain on the heater. ■ I want to eliminate uneven heating. → By filling the insulation material with heating elements, it becomes a full-area heater, allowing for uniform heating. ■ I want to create an original heater. → We can turn your requests into reality with custom-made designs. Additionally, due to our extensive experience, we can provide quick estimates and designs.
