The electric furnace heaters from Teitokusha, proud of their long lifespan! We shape various heaters.

At Teitokusha, we custom-manufacture heaters for electric furnaces that operate in harsh environments with extreme temperature fluctuations. For 126 years since our founding, we have been producing refractory materials (refractory bricks, insulators) and have developed unique technologies based on our expertise in heat resistance and insulation, providing innovative products. We solve problems related to specific requests and bring various heaters to life. Additionally, we take pride in the long lifespan of our heaters. We have a track record of them being used continuously for 20 to 30 years. Please consult us even for special items or those that have been declined by other companies. 【Features】 ■ Provision of innovative products through unique technology ■ Problem-solving for specific requests ■ Quick and careful responses to inquiries related to heating, cooling, and other thermal concerns ■ Provision of long-lasting heaters *For more details, please refer to the PDF materials or feel free to contact us.

Supports up to 900℃ in the furnace! Industrial electric heater that can be used in a clean environment.

The "Metal Frame Heater" provided by Teitokusha is an industrial electric heater that can be safely used in applications requiring a clean environment, such as metal heat treatment furnaces, semiconductor diffusion furnaces, glass heat treatment furnaces, and various experimental furnaces. It is suitable for various types of furnaces, including round and square pit furnaces, bell-type furnaces, box-type batch furnaces, tubular furnaces, roller hearth furnaces, and cart furnaces, without restriction on the type of furnace. In cases where insulation materials cannot be used in vacuum furnaces, we introduced the "FW type," a surface heater, to meet the conditions for uniform heating. The design required to prevent vacuum discharge and the ability to accommodate details such as fixing to the case and TC holes were tailored to the customer's requests, which they were very pleased with. 【Applications】 ■ Various metal heat treatment furnaces (quenching, annealing, homogenization, carburizing) ■ Various wire materials ■ Pipe continuous furnace processing (stainless steel, copper, aluminum, etc.) ■ Aluminum melting and holding furnaces ■ Brazing furnaces ■ Semiconductor diffusion furnaces ■ CVD furnaces ■ Weak current and electronic related continuous processing furnaces ■ Glass heat treatment furnaces ■ Various experimental furnaces, etc. *For more details, please refer to the PDF materials or feel free to contact us.

We respond to requests such as wanting to extend lifespan and introducing heaters that are less prone to disconnection!

The "Ceramic Fiber Heater" from Teitokusha is a heater capable of operating at temperatures up to 1200°C inside the furnace. We offer a lineup of heaters including strip-type heating elements that are space-saving and have high output, as well as round wire coil heating elements and irregularly shaped heating elements. We respond to requests such as "I want to extend the lifespan of the heater," "I want to introduce a heater that is less prone to breakage," and "I want to make a large furnace body as compact as possible." 【Case Studies】 <Case: I want to extend the lifespan of the heater> ■ Proposed and introduced a heater using a strip-type heating element (TELF-PISR type) - Can take a large power load per unit area, allowing for high output in a compact space - Excellent heat uniformity enables even heating of the object being heated ◎ After introduction: Lifespan doubled, power also doubled! *For more details, please refer to the PDF materials or feel free to contact us.

We will be closed from April 29, 2026 (Wednesday) to May 6, 2026 (Wednesday). We apologize for any inconvenience this may cause and appreciate your understanding. *Regarding inquiries made during the closure period, we will respond sequentially starting from May 7, 2026 (Thursday).

This is a notice of a limited-time special price campaign for everyone involved in factory wastewater management. We are offering a series of spectrophotometers that support COD, total nitrogen, and total phosphorus measurements at a special price for a limited time. Additionally, customers who purchase the eligible products will receive a portable pH meter as a gift (limited quantity).

We are pleased to announce that our company will be exhibiting at the following trade show. At our booth, we will propose solutions to challenges in manufacturing environments, such as "sticking," "slipping," "corrosion," and "wear," through various functional coatings, including fluoropolymer and PEEK coatings. If you have any concerns in the field or inquiries about prototype or mass production of coatings, please feel free to visit our booth. We sincerely look forward to your visit. 【Exhibition Overview】 ■ Exhibition Name: Monozukuri World 2026 Machine Elements Technology Exhibition ■ Dates: July 1 (Wednesday) - July 3 (Friday), 2026 ■ Venue: Tokyo Big Sight ■ Booth Number: E6-47 (East Hall 1) 【Main Exhibits】 ■ Fluoropolymer Coatings (PTFE, PFA, FEP, ETFE) ■ PEEK Coating "PEEKCOAT" ■ Ceramic Coating "Biceram" ■ High-Temperature Durable Fluoropolymer Coating "Thermo Pro Release" (for high-temperature release applications such as thermal welding and thermal crimping processes) ■ Thin Film Non-Stick Coating "NonStick STC" (for industrial knives and resin molding molds)

Door frame and door unit that can be installed on the same day. Since it has the same color variations as the steel partition, it allows for a unified design of the space. Three points: Point 1: Can be ordered together with the partition, reducing hassle during arrangement. Point 2: Simultaneous construction of frame and door allows for flexibility in the process. Point 3: No fire method, so there is no concern about risks from sparks.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
