Duct heaters (*custom-made products)

Duct heaters are gas heaters that are manufactured by applying tubular heaters and fin tubular heaters and are used as a heat source for hot air devices, heating furnaces, and heating appliances. They may have a flange on both sides or only on one side depending on the machine and location where they are to be installed. Depending on the type of objects to be heated, a drip-proof specification and a stainless steel specification are available.

They have a structure where heater elements are mounted on a steel flange by insulating retainers or bushings; heater terminals are stored and connected in a box; and wiring is completed up to the terminal block for power supply connection. They can be manufactured for a maximum operating temperature of 700°C.
