The "Use in the Chemical Industry" of DPH features a metal heating element inside that has distinctive structural characteristics. In processes like heating water, natural convection effectively heats the entire liquid, but when the viscosity is high, natural convection becomes less likely to occur, and the higher the viscosity, the more localized heating tends to happen. The internal metal heating element has a shape that promotes stirring and mixing, allowing the liquid to be naturally agitated as it passes through, enabling uniform heating. 【Features】 ■ Uniform heating is possible *For more details, please refer to the catalog or feel free to contact us.

The application example introduced in "DPH / Superheated Steam: Applications in Food" is "Next-Generation Food Processing and Heating Technology (Suppression of Lipid and Flavor Component Oxidation)." High-temperature superheated steam acts on the food, rapidly heating it. By manipulating the steam velocity, steam temperature, injection time, and injection position, we can differentiate between "Baking Mode," "Drying Mode," "Steaming Mode," and "Sterilization Mode," allowing for effective heating and cooking of food. We also introduce "Anaerobic Heating Technology" and "Reaction and Decomposition Technology," so please take a look.

The "DPH technology" is a pioneering technology that has started to become popular in recent years, utilizing advanced IH heaters that heat superheated steam and other substances. Instead of using nichrome wire, the metal heating element inside the pipe generates heat itself to heat gases or liquids. The core principle of "electromagnetic induction heating" involves passing high-frequency magnetic flux through the metal, which generates an eddy current within the metal. This eddy current, combined with the metal's intrinsic resistance, produces Joule heat, causing only the metal to heat up. The "Dual-Pax Heater (DPH)," which integrates the heating element and fluid for heat exchange, is based on this principle and is a device for heating gases or liquids. 【Features】 ■ Achieves efficient heat exchange with DPH structure ■ High durability ■ Large heat transfer area ■ Quick response ■ Thin film direct heating *For more details, please refer to the catalog or feel free to contact us.

The "Nano Steam Sauna" is a technology developed by our company, which has been patented and is currently under patent application. Using regular steam would quickly turn the room completely white, but this sauna uses super-fine particle nano steam created from overheated steam that reaches nearly 400°C, making it transparent even though it is steam when you enter the room. The nano steam, which has transformed into invisible super-fine particles, features higher penetration power than regular steam. You can stay in it for about an hour at a temperature range that puts less strain on the body, and we believe it can be actively utilized in medical and nursing care settings for bathing. 【Features】 ■ Higher penetration power than regular steam ■ Creates a transparent space that is indistinguishable from a high-temperature sauna ■ Room temperature is a relatively low 47°C low-temperature sauna ■ Perceived temperature is 80°C to 90°C ■ Excellent for beautiful skin and health *For more details, please refer to the catalog or feel free to contact us.

The DPH Dual Pax Heater "Utilization of Liquid Heating and Gas Heating" refers to the induction heating (IH heating) that is widely used in home appliances as an electromagnetic cooker. When high-frequency magnetic flux passes through metal, an overcurrent is generated within the metal. This overcurrent, along with the inherent resistance of the metal, produces Joule heat, causing only the metal to heat up. Since the metal itself generates heat, the thermal efficiency is extremely high, achieving instant heating. For more details, please download the catalog.
