The "PCH" we handle is a rod-shaped, high-power cartridge heater. It features a compressed and reduced diameter with a robust structure. It is used by inserting it into a workpiece that has been drilled. The standard lead wire length is 250mm, and the maximum operating temperature is 500°C (heater temperature). A version with a mounting flange is also available. 【Features】 ■ Possible outer diameter: Φ6 to Φ30 ■ Possible length: 50 to 1500mm ■ Material: SUS304, SUS316L, AH-1 ■ Lead wire length: standard 250mm ■ Maximum operating temperature: 500°C (heater temperature) ■ Mounting flange option available *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Silicone Rubber Heater" handled by Proheat. This is a flexible, lightweight, thin sheet heater that is insulated by sandwiching a heating element reinforced with glass cloth between silicone rubber sheets. It can be manufactured in various shapes, such as convex, concave, or donut shapes, to match the heating target. Due to the properties of silicone rubber, its use is limited to around 200°C (heater temperature), so it is mainly used for maintaining the temperature of containers or syringes filled with liquids, preventing condensation, and preventing freezing. 【Features】 ■ Insulated by sandwiching a heating element reinforced with glass cloth between silicone rubber sheets ■ Flexible and lightweight thin sheet heater ■ Can be manufactured in various shapes to match the heating target, including donut shapes ■ Made of silicone rubber, making it suitable for use in drip-proof environments *For more details, please refer to the PDF document or feel free to contact us.

The "Nozzle Heater" we handle is a compact version of a band heater, processed into a small-diameter cylindrical shape from a plate heater. It is a cylindrical heater specifically designed for nozzle heating in injection molding machines and extrusion machines, with the outer circumference designed to minimize protrusions to avoid interference with the surroundings. The power supply is lead wire type, which keeps the wiring neat. We also manufacture models with lead wire exit covers and sealed types as measures against resin leakage. Please feel free to contact us when you need assistance. 【Features】 ■ A compact version of a band heater processed into a small-diameter cylindrical shape from a plate heater ■ Specifically designed for nozzle heating in injection molding machines and extrusion machines ■ The lead wire type power supply keeps the wiring neat ■ Models with lead wire exit covers and sealed types are available as measures against resin leakage ■ Short delivery items (limited to standard/long) *For more details, please refer to the PDF materials or feel free to contact us.

The "plate heater" is a flat heater that consists of a mica board with a strip-shaped heating wire wrapped around it, insulated between two other mica boards, and further protected by a stainless steel plate as an outer casing. The power supply typically has lead wires coming out from the thickness part or has terminals (M5 bolts) raised on the surface. If there are obstacles such as bolt heads on the mounting surface, it is also possible to pre-process the plate heater with holes or notches to accommodate them. Standard products include a rich lineup such as "PPH-05080" with a length of 80mm and "PPH-15450" with a length of 450mm. 【Specifications (partial)】 ■ Possible width: 25–300mm ■ Possible length: 50mm and up ■ Thickness: 4mm ■ Maximum operating temperature: 350℃ ■ Power supply voltage: 100v/116v/200v/220v/240v ■ Recommended watt density: up to 3.5w/cm2 *For more details, please refer to the PDF document or feel free to contact us.

The "band heater" is a cylindrical heater made by bending a plate heater into a cylindrical shape, which can be mounted using a stainless steel band on the outside. Basically, it comes in 1P or 2P types, but larger diameters may have 3P types or more. Like plate heaters, it is also possible to perform hole processing or notching in advance. Additionally, shapes such as oval, barrel, or polygon can be manufactured to match the heating target. 【Features】 ■ Can be mounted using a stainless steel band on the outside ■ Like plate heaters, it is possible to perform hole processing or notching in advance ■ Shapes such as oval, barrel, or polygon can be manufactured to match the heating target ■ The 1P type is formed from a single heater into a circular shape ■ The 2P type is formed from two heaters, and the opening can be accessed by removing the tightening band *For more details, please refer to the PDF document or feel free to contact us.

The "sheath heater" is a rod-shaped heater that encloses a spiral-wound heating wire (nichrome wire) within a metal pipe, insulated with magnesia powder. Power terminals (M5 bolts) extend from both ends, allowing for a bendable structure. It can be bent into shapes that match the heating target. Primarily, it is used as a heat source for dryers and electric furnaces for air heating, but it can also be used for heating liquids (water, oil, chemical solutions, etc.). 【Features】 ■ The spiral-wound heating wire (nichrome wire) is enclosed in a metal pipe and insulated with magnesia powder. ■ Power terminals (M5 bolts) extend from both ends. ■ It can be bent into shapes that match the heating target. ■ It can be widely utilized in various shapes according to application needs. *For more details, please refer to the PDF document or feel free to contact us.

The "cartridge heater" is a rod-shaped heater that encloses a coiled heating wire (nichrome wire) within a metal pipe, insulated with magnesium oxide. It is similar to a sheath heater, but since the power supply wire exits from one end face, the wiring is simple and neat. It is strong due to its compressed reduced diameter, and the surface of the pipe is also finished with high precision polishing, allowing for efficient heat conduction to the heated object. We also manufacture models with flanges or bushings for fixing, so please feel free to contact us when you need assistance. 【Features】 ■ Encloses a coiled heating wire (nichrome wire) within a metal pipe, insulated with magnesium oxide ■ The power supply wire exits from one end face, making wiring simple and neat ■ Strong due to its compressed reduced diameter, and the pipe surface is finished with high precision polishing, allowing for efficient heat conduction to the heated object ■ Models with flanges or bushings for fixing are also available *For more details, please refer to the PDF document or feel free to contact us.
