It is called the "last resort for the heater industry." This is because our engineers respond to even the most difficult requests. "Our motto is 'We never refuse a request!'" If you are considering a sheath heater, please feel free to let us know anything you need. Thanks to our unique 3D bending technology, it is possible to create quite complex shapes with sheath heaters. This has made it possible to use sheath heaters in places that were previously thought to be impossible. We can produce original heaters from just one unit, thanks to our "complete made-to-order production system." Sheath heaters require appropriate design and selection based on their application, including sheath material and watt density. Even if your needs are not specific, if you have requests such as "I want to avoid uneven temperature distribution," "I want to handle high temperatures," or "I want to extend the lifespan," please feel free to contact us. Our "thermal engineering technology" will solve your concerns and wishes. Thermal Engineering Technology has celebrated its 50th anniversary as a specialized manufacturer of industrial, commercial, and business heaters. We will continue to respond to customer requests starting from just one unit.

In the manufacturing process of industrial products, almost everything goes through a process called "heating." Ceramic tiles, which are used as flooring materials, are fired at high temperatures, while acrylic, the material used for signs, involves pouring heated liquid resin into molds and allowing it to solidify and shape over time. When it comes to materials, it is clear that various industrial products around us, including plastic materials such as PVC and polyethylene, as well as metal production, paper manufacturing, and fabric production, are all made through the heating process. There are options for using either fire or electricity for heating, but among electric options, cartridge heaters are particularly easy to control and safe, making them widely used in various applications. *For more details, please refer to the PDF document or feel free to contact us.*
