What Is a Heating Apparatu
A heating apparatu is a device used to heat various objects, such as scientific chemicals or samples, using combustible gas or electricity.
Generally called “heaters,” there are a wide variety of products in circulation, ranging from industrial products capable of heating up to 1,000°C or higher to so-called “induction heaters” and “electric heaters” for general household use.
In recent years, in addition to improvements in production technology, heating using electricity has become more common due to the ease of securing a heat source (power supply) and safety.
Uses of Heating Apparatus
Heating apparatus are used in variety of industries because they are extremely versatile.
In industrial product R&D applications, heaters are used for “chemical heaters,” which are immersed in a chemical solution and heated from the inside, and heaters for “thermostatic storage,” which are used to store easily dispersible chemicals and powdered objects in a high-temperature state. In addition, “bar heaters” or “electric stoves” are used to heat materials in oil when hard-fitting ring gears, bearing inner races, and the like.
In addition, “high-frequency heating apparatus” that can heat up to extremely high temperatures are used as metal melting furnaces because they can self-heat metals to ultra-high temperatures exceeding 1,000°C without contact.
Features of Heating Apparatus
Taking the aforementioned product as an example, a “chemical heater” is a “rod heater” coated with a fluoroplastic or other material that excels in corrosion and weather resistance, so it is resistant to erosion even when immersed in a chemical solution.
Also, “rod heaters” used for heating liquids such as water and oil can directly heat the liquid from the inside of the container, rather than from the outside, thus reducing the time required for temperature rise.
Unlike “high-frequency heating apparatus” and “IH heaters” that use Joule heat generated by electric heating wire or heating element, “high-frequency heating apparatus” and “IH heaters” use “self-heating phenomenon (Joule heat)” generated by electromagnetic induction, so that the entire object can be heated evenly and the output can be easily controlled from low to ultra high temperatures. The temperature can be easily varied from low to ultra-high temperatures by controlling the output power. In the case of metal melting furnaces, the electromagnetic force stirs the inside of the furnace, and this feature makes the furnace very easy to use in terms of operator load and work environment.
Other products using silicone rubber can be freely deformed. Those using transparent conductive films, such as those used to prevent fogging of glass, have the feature of not interfering with vision.
