NIDS Sterilization Technology Is
forcible and attractive

We provide solutions applicable to
various industries for improving air quality.

For industrial facilities

Pre-treatment system removesvarious odors, toxic gases, ultra fine dust, and smog in the air in indoor multi-use facilities.
Effective for removing odor and harmful substances that could not be eliminated when combined with ECP, Scrubber, RTO, Bio-Filter, and others.
Effective for increasing cooperation efficiency when used in existing deodorization facilities, including dehydration treatment plants.
Especially effective for deodorization, and odor and air purification to improve working environments inside manufacturing lines.

Superstores(installed on AHU air supply ducts)

Dehydration treatment plants(dealing with civil complaints about odor and emissions and creating a green workshop environment)

Production facilities and manufacturing lines(removal of internally generated odor)
For office work/schools

Excellent for creating a pleasant building environment by purifying indoor air circulating through
air handling units (AHU) and air pollutants from outside when many people live in the same space.
We provide an effective solution for removing stench and ammonia generated from the inside of toilets and preventing them from spreading.

Potable toilets (indoor sterilization and deodorization)

Inside of school classrooms (air sterilization and deodorization)

Animal hospitals (odor removal)

Day care centers (deodorization and sterilization)
For family/business use

Immunization is conducted by making an indoor environment safe and pleasant by removing floating bacteria and viruses indoors and improving hygienic conditions at home and in hospitals.
Applicable to various air conditioning system equipment, including air handling units (AHU) or AIO and suitable for removing floating viruses or bacteria in the air.
We provide a solution effective for removing odor as well as cigarette smoke generated from smoking areas, and that can resolve civil complaints by preventing damage from second-hand smoke

Home air conditioners (for food and cigarettesmells)

Hospitals and medical centers (for indoor air purification)
As built-ins

Various ceramic modules and AIO that we employ have an excellent effect on purifying water and air.
Removes inflowing odors and other VOCs, enabling maintenance of pleasant conditions following improvement of an indoor environment.
Protects the health of drivers and fellow passengers from car air handling units.
Used as a sterilization and deodorization module inside water purifiers, effective for maintaining clean conditions by containing the propagation of bacteria and molds. Additionally, under the sink, application is possible and effective for removing various viruses, bacteria and odors.
Extends fruit preservation periods by removing ethylene as a powerful foul odor remover in storage facilities, used for storing fruits and keeping them fresh.

Bidet(odor removal, sterilization)

Water purifier (Water + air purification)

Car air handling unit (odor removal + sterilization)

Elevator(odor removal + sterilization)

Ventilation system (indoor air quality improvement)

Fruit storehouse(extension of fruit preservation periods by removing ethylene, bacteria propagation prevention, preservation of freshness)

Air curtain(sterilization and deodorization)

Shortcut to Plasma Module

Plasma

We have found eco-friendly air sterilizeation effects from natural phenomena such as lightning.

Plasma, in the fourth state of matter, is a complex of ionized gases formed during gas discharge,
used for fluorescent lights and semiconductors in daily life and various medical fields.

Principle of Plasma Sterilization

electrode surface is divided into “active hydrogen ion” and
“oxygen ion,” which is referred to as the plasma state.
Forms OH Radical and OHH Radical by reacting in the air and removes 99.9%
of harmful substances (viruses, bacteria, and mold) in the air.

Plasma Deodorization

Active hydrogen ions and oxygen ions formed through plasma form ion
clusters, including free radicals (OH Radical) highly reactive in the air.

Through this, harmful chemical substances in the air

are disintegrated intoharmless molecules
water(H₂O),oxygen (O₂),and carbon dioxide (CO₂)

Removes the five major harmful gases

Chemical substances	Chemical formula	Decomposition reaction formula by ion cluster
Ammonia	NH3	4NH3 + 3O2→2N2 + 6H2O
Toluene	C7H8	C7H8 + 9O2→7CO2 + 4H2O
Benzene	C6H6	2C6H6 + 15O2→12CO2 + 6H2O
Ethylene	C2H4	C2H4 + 3O2→2CO2 + 2H2O
Formaldehyde	CH2O	CH2O + O2→CO2 + H2O

Chemical substances, chemical formula, decomposition reaction formula by ion cluster Oxygen ions and radicals held together
“form ion clusters.”

01Plasma discharge by discharge tube

02Ionization with oxygen molecules in the air

03Reaction of oxygen ions with water molecules : the creation of radicals

Ion Cluster

Ion clusters usually, as a complex of 10~60 molecular oxygen ions, exist in waterfalls and forests through sunlight in the air.
Ion clusters have excellent effects for “air purification & odor removal &antibacterial sterilization,” as the key technology of eco-friendly air sterilization.

Differentiation of technology

Differentiation of NIDS Plasma Technology

01
“NIDS” releases ion clusters and destroys viruses within 0.002 seconds.
Ion clusters spread to every corner of rooms with a definite infection effect.
02
As viruses are smaller than a filter hole, sterilization through filters has a limitation.
However, “NIDS” can destroy 99.9% of viruses missed after going through filters.
03
Ion clusters reaching every corner of rooms can control not only
the surface of rooms but also indoor air quality in a clean state.
04
Ion clusters have an outstanding effect on decomposing chemical substances,
volatile organic compounds and odor.

Are NIDS plasma “OH radicals” safe?

: The U.S. EPA (U.S. Environmental Protection Agency) provides
confirmation of the effectiveness and safety of oxygen anionic
substances generated in the plasma state, regarding their
removal of COVID-19 viruses, odor and ultrafine dust.

: According to the “Evaluation guideline for natural sciences-based
treatment equipment for stab wounds treatment using plasma,”
it is stated that OH radicals as heterogenic oxygen anionic substances
generated by applying energy are harmless to the human body
with outstanding oxidative power.
