Compact and durable cartridge heaters
Cartridge heater
Cartridge heaters are shaped like a pipe with a lead wire drawn out from one end, and are inserted into the object to be heated for effective heating.
The specially filled heaters are compressed until the internal insulating material no longer breathes, making them resistant to vibration shock.
It is mainly used as a heat source for electric heating panels for presses, molds for molding machines, and various automatic machines. It can also be used for liquid heating by welding processes such as bushings.
Features of Cartridge Heaters
①High quality high wattage cartridge heaters have very high insulation properties at high temperatures.
(2) Heater life is long and can be used with peace of mind.
(3) Insulation measures are taken to suit Japan’s high temperature and humidity climate environment.
Sheathed heater with excellent versatility and electrical insulation performance
Seed heaters
Sheathed heaters are used for direct heating, but at the same time are basic heaters that can be used as materials for casting heaters, far-infrared heaters, and throw-in heaters.
The surface temperature of the heater’s outer pipe can be manufactured up to 850°C. The heater’s outer pipe is completely electrically insulated.
The outer pipe of the heater is completely insulated electrically, so it can be used safely if only the connection terminals are taken care of.
The heater outer pipe can be made of the most suitable material according to the intended use. Copper, steel pipe, stainless steel, incoloy, etc. can be used.
Sheathed heaters can be fitted with fins to increase the heat transfer area. These finned heaters are used in packaged heaters for air conditioning and heating, warm air heaters, and other applications that require a large heat source in a relatively small space.
Sheathed heaters can be manufactured in a variety of shapes, from straight to special shapes to suit the purpose of use. We can also manufacture Teflon-coated heaters with excellent chemical resistance for use in heating chemicals.

Heater for hot air generation optimized for the machine and location of installation
Electric heaters for hot air generation are gas heating heaters manufactured by applying metallic pipe heaters and porcupine heaters.
The heaters are made of thin stainless steel fins with good heat dissipation on the outside of the element and are used as heat sources for hot air generators, dryers, ducts, etc. to supply the required amount of heat to the required locations.
We can manufacture various shapes such as square flange type, round flange type, etc., depending on the machine and location of installation.
Circulation heater for fluidized circulation superheating of liquids and gases
Circulation heaters incorporate a throw-in heater to heat liquids and gases during fluid circulation. They are designed and manufactured to heat water, oil, solvents, solutions, and other liquids for liquids, and steam, drying, preheating, air heating for sintering, and other gases in the course of the pipeline for gases.
The structure is easy to install and use, the temperature can be adjusted, and if necessary, a controller can be installed to prevent overheating and damage to the heating element.
