What is CHEFER’s Core Technology: Cold Plasma?
Applications utilizing the characteristics of plasma, sards semiconductor manufacturing,Sterilization,disinfection, and medical settings are being developed in various fields.The cold plasma module adopted by CHEFER is smaller and consumes less power than traditional products.
This advancement is expected to make plasma technology more accessible and easier to utilize.
About the Plasma State
If you have heard the word “plasma,” few people know it in detail.Plasma is the fourth state of matter, which occurs when even higher energy is added tosolid, liquid, and gas. In this state, electronsseparate from atoms, resulting in a highlyactive mixture of ions and electrons.
In our everyday environment, examples of plasma include lightning, auroras, the sun, and candle flames. It is said that more than99.9% of the matter in the universe is plasma. In practical applications, plasma is used in fluorescent lights and neon tubes and in industrial processes such as arc welding for metal fabrication.



Plasmas” around us include the sun, lightning, aurora borealis, and neon tubes.
What is Cold plasma?
With the evolution of plasma technology, it has become possibleto stably generate plasma at low temperatures and atmosphericpressure, environments previously achievable only under vacuumor high temperatures. This type of plasma is referred to as “cold plasma” in contrast toconventionally high-temperature plasma.Cold plasma has been used in semiconductor manufacturing andvarious industrial equipment. Its ability to decompose organicmatter such as viruses, bacteria, and mold at low temperatureshas recently led to its application in fields like infection controland food waste reduction.
However, conventionally cold plasma generators require high voltage, necessitating separate devices for transformers and high-frequency generators. Consequently, these devices become large, consume much power, and are limited to specialized environments.

Until now, cold plasma has been used mainly to manufacture semiconductors and other products.
The Birth of a Revolutionary Compact and Lightweight Cold Plasma Module
The CHEFER PLASMA MODULE generates plasma at temperatures below 50°C. It is characterized by its ability to produce large quantities over a surface rather than at a single point.


CHEFER has leveraged the control technology for plasma power supplies and mass productiontechniques accumulated by engineers to develop the world’s first cold plasma module usingan original transformer: the "CHEFER PLASMA MODULE."
The CHEFER PLASMA MODULE is compact and lightweight, generating plasma with low energyconsumption. The miniaturized CHEFER PLASMA MODULE is expected to be applied in variousfields, including air purifiers, water treatment equipment, carbon dioxide decomposition, and medical devices.
