Custom tubular furnace designed to meet specific applications, including pipe diameter, heating zone, atmosphere, and instrumentation.

We offer "custom tubular furnaces" designed to meet the specifications tailored to your applications. In standard tubular furnaces, there may be cases where the tube size, heating zone length, heating rate, processing temperature, atmosphere gas, and instrumentation configuration do not match, making it impossible to reproduce the desired testing conditions. Our tubular furnaces are designed for stable operation at approximately 1200°C, with the heating zone, tube size, gas lines, measuring instruments, sampling ports, and other components customizable according to your needs. We can accommodate various gases such as inert gases like N2/Ar and H2. We will propose specifications based on your desired furnace dimensions, temperature conditions, and atmospheric conditions. 【Features】 ■ Design of tube size and heating zone length according to application ■ Consideration of furnace configuration based on heating rate, temperature distribution, and processing volume ■ Compatibility with various gas atmospheres such as N2/Ar/H2 ■ Selection of instrumentation such as thermocouples, MFCs, pressure gauges, and O2 meters ■ Custom solutions for sampling ports and exhaust lines *Please feel free to consult us even if the specifications do not match the standard products.

Applications/Examples of results

【Challenges】 ■ The standard product does not match the pipe diameter, pipe length, and heating zone length. ■ Furnace dimensions tailored to sample size and jig dimensions are necessary. ■ Heating rate, temperature distribution, and holding time need to be customized for specific applications. ■ Ambient gas conditions such as N2, Ar, and H2 need to be designed individually. ■ Simultaneous management of material temperature, gas flow rate, furnace pressure, and O2 concentration is desired. ■ Additional sampling ports and exhaust lines are needed. 【Applications】 ■ Small sintering furnace for research and development. ■ Evaluation of conditions for powders, catalysts, metals, ceramics, and battery materials. ■ Assessment of sample shapes and processing conditions that cannot be handled by standard furnaces. ■ Custom tubular furnace to replace specifications of existing equipment. Even at the stage where conditions are not finalized, it is possible to consider specifications based on sample dimensions, temperature, atmosphere, and necessary instrumentation.
