STERILIZZATORE D’ARIA
TWIST
+ Timer Room
FUNCTIONAL CHARACTERISTICS
With UVC TWIST® your environment is completely saniti-
zed. UVC TWIST® is a UWC lamp system designed and pa-
tented by Isotech, which sanitizes both air and surfaces depen-
ding on the need and the moment.Two powerful 55 Watt UVC
lamps with a T8 diameter are installed on the UVC TWIST®
with a 2-pin double terminal. The installed lamps have a typi-
cal UVC irradiation with the maximum output at a wavelength
of 253.7 nm with an irradiance of 1.7 watts/m2 at one meter distance.
When the lamps are turned towards the inside of the channel that contains them, they act by sanitizing the air,
when the lamps are turned towards the outside of the channel they radiate the environment towards which they
are turned, sanitizing it. The air sanitization is activated continuously and in the presence of people in the envi-
ronment, thus ensuring maximum reduction the risk of breathing viruses or bacteria. With an empty environment,
ie without people, the “Clean Surface” command can be activated, the lamps facing the channel turn 180 degrees
and radiate the surface towards which they are facing, emitting their UV irradiation for inactivation of microor-
ganisms by sanitizing surfaces and the whole irradiated environment.
The controls for choosing the “Clean Air” or “Clean Surface “ function are located outside the room. In the pre-
sence of people entering during the “Clening Surface” function, a presence sensor switches off the lamps which,
by turning 180, automatically return to the position that sees them facing the inside of the sanitizing chamber.
UVC TWIST® has separate controls. The “Cleaning Air” air sanitization can be programmed while the “Clea-
ning Surface” function can only be activated manually through a timer.
UVC TWIST® can be installed individually or in parallel (multiple units connected within the same environment).
To facilitate installation, the UVC TWIST® is equipped with hooks (to be hung from the ceiling) and anges
(to be attached to the plasterboard or to the wall). A rotation “closure” system prevents UVC light from escaping
when the lamps are facing the germicidal chamber.
Caution !!
This product must be considered and used only as a device for the disinfection of environments, therefore surfa-
ces and air in a confined environment, depending on the mode chosen with the use of UVC lamps.
Use is allowed only in the absence of people or other living beings during the sanitization
treatment in the “Cleaning Surface” mode. Use is also allowed with people present but only
in the “Cleaning Air” mode.
Any other use is to be considered improper and therefore dangerous.
The ISO ITALIA GROUP company declines any responsibility in the event of improper, erroneous and
unreasonable use that goes beyond the provisions of this manual.

12
TIMES OF USE UVC TWIST
Referring to the declared irradiance for the lamps used in terms of UVC energy,
1.7 w / m² at a distance of one meter in relation and to the doses reported in the official tables for the destruction
of microorganisms, we can indicate that, with the cycles shown below in the different configurations, the killing
of 99% of bacteria on surfaces and objects is achieved that are irradiated.

13
From the locked condition with the red security
lock light on, it is possible to reactivate the system
by pressing the illuminated reset button for a few
seconds.
Caution !!
Before starting each sanitation cycle in the
“Cleaning surface” mode, it is mandatory to make
sure that there are no people or other living beings
in the environment to be treated as poten-
tially harmful UVC radiation is used.
The presence detection system could determi-
ne the block even outside the sanitation cycles
in the “Cleaning Surface” mode. It will therefore be necessary to press the reset command before giving
the start.
The timer emits a 10-second sound at the end of the work session, only when the cycle is carried out correctly for
the entire set time.
COMMANDS
A control console is provided for the operation of the system, to be installed outside the environment to be sani-
tized. (For dimensional indications refer to the paragraph on technical characteristics).
The components present on the console are:
• A control console is provided for the operation of the system, to be installed outside the environment to be

TECHNICAL INFORMATION ON THE USE OF UVC IN ISO TECH PRODUCTS
UV-C radiation is a proven and effective technology for destroying micro-organisms
Iso Italia Group, with over 30 years of experience in UV lamp sector presents its product line for disinfection with
UVC Steril Line germicidal lamps.
Germicidal lamps emit very short ultraviolet waves, deadly to micro-organisms.
Some information about Germicide lamps
Ultraviolet rays emit a very high energy level light with a wavelength between 200-400nm. In particular, radiation
with a 254nm wavelength has been scientically proven to be extremely effective for disinfection. More than 90%
of the total UV radiation emitted is just 254nm. Wavelengths of 200-280nm are called UVC. Thus disinfection
using 254nm wavelength is called UVC Disinfection. Radiation of 254nm destroys micro-organisms by changing
the genetic information contained in their DNA, ensuring a 99.99% reduction.
Safety of UVC germicidal systems
Since UV-C rays present a danger to the skin and eyes, direct exposure to the rays should always be avoided. The
UV-C is blocked by a number of materials, including glass and most transparent plastics, so you can safely observe
a UV-C system if you look through a shielding system. UV-C provides disinfection without residues of any kind,
however these systems do not imply the need to eliminate or neutralise dangerous products after disinfection.
UVC germicidal systems are fast, inexpensive and eco-friendly, as no chemicals are added to air / water and there
are no hazardous or toxic chemicals to dispose of.
Benets of UVC germicidal systems
Disinfection times are rapid, with a typical disinfection cycle lasting about 15 minutes (excluding germicidal air
systems). This allows extremely fast turnover times for sanitising environments. For its simplicity, UV-C disin-
fection is extremely easy to use. All surfaces within a certain distance, will observe a certain level of disinfection
for a certain period of time, provided that the light is not blocked and can reach the surface. It becomes very easy
to plan the use of a UV-C disinfection system when you are familiar with the simple usage protocols.
Applications of UVC germicidal systems
The applications of our germicidal systems are many and ever more numerous.
Systems are available for the disinfection of environments, air, objects and equipment, air conditioning ducts,
ambulances and other vehicles, ducts, belt conveyors and many other applications.
The guaranteed effectiveness of UVC systems
Out manufacturing unit knows the energy produced by all pieces of equipment, calculated by the number and
from the type of lamp used and by its designated function (application) (air purication, objects, environments).
From these technical values we determine the “DOSE” of UVC produced by each device (i.e. the energy of the
device multiplied by the ignition time. This type of calculation allows us to be sure of the germicidal efciency,
as in medicine, on a global level, tables are used that indicate the required "DOSE" of UVC required to eliminate
all bacteria, spores and viruses.

15
UV BASICS
Ultraviolet light belongs to the electromagnetic spectrum with a wavelength between 200 and 400 nm (nanome-
ters), which is shorter than visible light, but longer than X-rays. All UV rays and bands are invisible to the human
eye.
The UV spectrum can be divided into the following bands:
UV-A (Long Waves; 400-315 nm): Used for Black Lights, Skin Tan, Ink/Resin Hardening.
UV-B (medium waves; 315 – 280 nm): used to treat psoriasis, may cause sunburn, skin cancer.
UV-C (short waves; 280 – 200nm): more effective for germicidal disinfection.
UV-V (UV under vacuum, less than 200 nm): may produce ozone in the air.
All of the above wavelengths of UV light are emitted from the sun, but only the longest wavelengths, UV-A
and UV-B reach Earth. UV-C rays, which are the shortest wavelength but the highest energy, are blocked by the
ozone layer.
INACTIVE MICRO-ORGANISMS
Because UV-C rays are blocked by the ozone layer, micro-organisms have not developed a natural defence
against UV-C energy. When the DNA of a micro-organism absorbs UV-C energy, molecular instability occurs,
resulting in interruption of the DNA sequence. This makes the cell unable to grow or reproduce. Without the
ability to reproduce, the cell cannot infect and dies quickly.
The application of UV-C energy to inactivate micro-organisms is
known as germicidal irradiation or UVGI. It has been used for this
purpose since the early 1900s. Artificial UV-C energy is produced
in germicidal ultraviolet lamps that produce UV radiation by ion-
ising mercury vapour at low pressure. These lamps are similar to
typical fluorescent lamps for domestic use, but do not have the
phosphorescent coating that transmits soft white light. Most com-
mercial UV-C lamps are low-pressure mercury lamps that emit
UV energy at 253.7 nm, which is an ideal wavelength for disrupt-
ing the DNA of micro-organisms.
UV-C lamps and devices are increasingly used worldwide in vari-
ous configurations and applications to disinfect water, air and sur-
faces.

16
DOSAGE DETERMINES EFFICACY
The amount of UV-C energy required to inactivate a given micro-organism is measured on the basis of the dose,
which is determined by a combination of radiation energy and exposure time. A key difference between surface
inactivation and airflow inactivation of micro-organisms is exposure time. The residence time in the UV field for
micro-organisms in the airflow is in the order of seconds and would require a much higher UV-C dose compared
to surface application. Scientists have determined the rates at which various microbial populations decrease due
to exposure to biocidal factors such as UV-C irradiation. Organisms differ in their susceptibility to UV-C inac-
tivation; in general, viruses are the most sensitive to UV-C rays followed by bacteria with fungal moulds and
spores that are the least sensitive.
UV-C irradiation also obeys the inverse-square law of light, where the intensity at a given point is inversely
proportional to the square of its distance from the light source.
To date, the dose in Joules has not yet been officially established to inactivate COVID-19 because to obtain the
exact data means waiting for the technical laboratory times, which should be made official by the end of October.
However, all bacteria and viruses tested to date (many hundreds over the years, including coronaviruses) are
eliminated by UV disinfection. UVC rays (or germicidal range), inactive (i.e., “kill”, “eliminate”) at least two
other coronaviruses that are the closest relatives of the COVID-19 virus: SARS-CoV and MERS-CoV (“Large-
scale preparation of UV-inactivated SARS coronavirus virions for vaccine antigen”, Tsunetsugu-Yokota Y et al.
Mol Biol Methods. 2008; 454:119-26. doi: 10.1007/978-1-59745-181-9_11.; “Efficacy of an Automated Mul-
tiple Emitter Whole-Room Ultraviolet-C Disinfection System Against Coronaviruses MHV and MERS-CoV,

Disinfection When Fighting COVID-19”; William A. Rutala, PhD, MPH, CIC, David J. Weber, MD, MPH;
Infection Control Today, March 20, 2020 (https://www.infectioncontroltoday.com/covid-19/focus-surface-disin-
fection-when-fighting-covid-19). However, the efficacy condition of UVC light remains related to THE DOSE,
i.e. the energy with which the light reaches the target to inactivate it. UVC systems must therefore be designed
to ensure the DOSE required to inactivate the viruses for the environments and applications for which they were
designed.
