冨岡産業 List of Products and Services

In our company, when installing "explosion-proof heaters" in hazardous locations, we design and manufacture them based on the "Guidelines for Explosion-Proof Electrical Equipment in Factories." Additionally, if certification from the Industrial Safety Research Institute is not required, we can also manufacture semi-explosion-proof types designed and produced in accordance with the explosion-proof guidelines. Please feel free to consult us if you have any requests. *Please note that general electric heaters on their own are not subject to testing under the explosion-proof guidelines, so we recommend that you undergo explosion-proof testing for the entire equipment or system that incorporates the explosion-proof heater. *For more details, please download the PDF or feel free to contact us.

The "cast-in heater" is a heater that incorporates a sheath heater into cast materials such as aluminum and iron, allowing it to be closely attached to the object being heated. It is suitable for uniform heating against a "surface" and can be produced in shapes ranging from simple ones like heat plates to more complex designs. Additionally, by using a cartridge-type heater and minimizing the gap between the cast and the heater through micro-processing, it becomes possible to insert and remove the heater, improving efficiency during maintenance and other operations. 【Specifications】 ■ Sheath material: STP, SUS ■ Sheath diameter: 8–14Φ ■ Internal shape: Custom shape according to usage range ■ Main body shape: Custom shape according to installation and usage conditions ■ Terminal specifications: Various terminal types available ■ Surface treatment: Various treatments such as mechanical processing and coating are possible ■ Others: Can be used in conjunction with cooling pipes, etc. *For more details, please download the PDF or feel free to contact us.

The "mounting type heater" is a heater that has been designed for easy installation and removal by welding mounting screws and other components to the outer pipe of various types of sheath heaters. Depending on the specifications of the mounting part, it is possible to change the shape and dimensions of the mounting screws. It can be used by directly inserting it into gases, liquids, other light metals, molten slag, etc. 【Specifications】 ■ Screw length C: 13 to any length ■ Screw diameter M: M12 to any diameter ■ Flange diameter ΦD: 22Φ to any diameter ■ Flange thickness t: 3t to 6t ■ Screw material: BSBM, SUS ■ Shape: Various shapes are possible in addition to the examples shown. *For more details, please download the PDF or feel free to contact us.

The "flange heater" is a heater that has a sheath heater welded to a plate flange, allowing it to be mounted on a pipe flange. It can be used in areas that require airtightness or where high pressure is applied. Additionally, the diameter of the flange and the arrangement of the heater can be freely manufactured. 【Basic Specifications of Flange Part (JIS5K)】 ■ Type: 50~400A 　・H: 60～ 　・T: 14～ 　・Φh: 15～ 　・B: 130～ 　・C: 105～ *For more details, please download the PDF or feel free to contact us.

The "cartridge heater" is available in both single-phase and three-phase versions, and it has excellent features in terms of space and cost. The terminal section can be made to suit the usage conditions, with options for general heating and waterproof types. Due to its unique heating wire configuration, the terminals are gathered on one side, allowing for concentrated local heating simply by inserting it into pre-prepared holes, even in narrow spaces or complex shapes of non-heated bodies. 【Lineup】 ■ Standard type ■ Waterproof type ■ Flange type ■ Waterproof flange type ■ Plug type ■ Waterproof plug type *For more details, please download the PDF or feel free to contact us.
