We would like to introduce the "Fin Heater" offered by Churitsu Electric Co., Ltd. This product comes in two types: one that wraps a steel band around a sheath heater, and another that passes an aluminum plate through and compresses it onto the sheath heater. Due to the installation of fins, there are constraints on the bending processing of the heater. Please feel free to contact us if you have any inquiries. 【Material Specifications】 ■ Pipe Material: SUS304, Inconel 840, Inconel 800, A1060 ■ Suitable Environment: Air Heating *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce "Die Casting and Gravity" offered by Churitsu Electric Co., Ltd. In addition to aluminum casting for sheath heaters, we also perform crimping processes on aluminum parts. We carry out aluminum casting using two methods: die casting (high-pressure casting) and gravity casting (low-pressure casting). 【Features of Die Casting】 - For heater casting, BUNDY (iron + copper plating) is used. - For heater crimping, aluminum pipes are used. - Due to die casting, the surface finish is smooth, allowing for fine machining. - It is possible to apply paint to the aluminum surface. 【Examples of Product Applications】 - Irons, hot plates, steam ovens, rice cookers, humidifiers, ice makers. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce the "Boiler Unit" offered by Churitsu Electric Co., Ltd. It is assembled by welding a sheath heater to a stainless steel tank, and we offer two types of tanks: sealed and open. A compact design that saves space is possible. Since it mainly uses high-output heaters, a dry-running prevention device is necessary. 【Material Specifications】 ■ Pipe Material: Incoloy 840, Incoloy 800, SUS316L ■ Tank Material: SUS304, SUS304L, SUS436 ■ Suitable Environment: Liquid Heating ■ Maximum Operating Pressure: 40 BAR *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Flat Heater" offered by Churitsu Electric Co., Ltd. Due to its flat shape and thin thickness, it can be bent at a small radius. It can use a three-phase power supply with just one unit. However, because it is flat, there are restrictions on the bending angle. Please feel free to contact us if you have any inquiries. 【Material Specifications】 ■ Handling Diameter: 25×7, 25.4×6.35, 25.7×6 ■ Material Composition: SUS304, Incoloy 800 ■ Maximum Operating Temperature ・SUS304: 650℃ ・Incoloy 800: 760℃ *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Cartridge Heater" provided by Churitsu Denka Co., Ltd. This product is a sheath heater with the connection terminal consolidated to one side.
