General questions

_
For which areas of application can the device be used?

You can use DISINFECT plus in any room where you want to reduce germs, especially in: Laboratories, ambulances, containers, isolation rooms, normal sickrooms, intensive care rooms, operating rooms, storage rooms, food areas, and much more.

How much time does it take to decontaminate?

Depending on the reduction level, between 30 and 60 minutes – including preparation and post-processing approx. 2-3 hours

Questions about DISINFECT plus

_
What should I do when the device cannot be started?

If the device cannot be started, disconnect and reconnect it. The power connection used may be defective. It can be checked with a commercially available lamp or another electronic device. If in doubt, or if the device cannot be restarted, contact our service technicians.

What should I do if the device starts up but the screen does not show anything?

After each shutdown, you have to wait for a minute before DISINFECT plus can be switched on again. The power supply of the computer does not switch off immediately and a restart is only possible when all systems are switched off. Switch it off again and wait a minute before starting again. If in doubt, or if the device cannot be restarted, contact our service technicians.

What should I do if the canister is locked?

If the system detects tampering with the canister by increasing the weight, the canister used is blocked for safety reasons. In this case the canister must be replaced.

What should I do if there are smoke detectors in the room?

Smoke detectors, especially those with optical sensors, can trigger a fire alarm. The fire protection officer must clarify in advance what type of smoke detector is used and how it should be deactivated.

What should I do if there are ventilation exits/inlets in the room?

Ventilation can be deactivated by the building’s technical staff. Nevertheless, all air inlets and outlets must be sealed airtight before DISINFECT plus can be used.

What should I do after a power failure during operation?

Protective equipment must always be worn during operation before the room can be entered. On the device screen you can read the status message and the reason for the switch off. If you have attached the device to a network and started it from outside, you can also view the messages from another computer.

What should I do if the program cannot be started?

Check the status message. The start conditions must be within the tolerance range. Furthermore, the selected program must match the canister used. Is the liquid okay? If everything is OK, restart the device and try again.

What should I do if the canister is not recognized?

Check the position of the RFID reader and the tag. If damage can be seen during the day, the canister can no longer be used. Exchange the canister. If you have no other canisters available and decontamination is necessary for whatever reason, there is the option of activating the system for decontamination. Contact our support.

 

If there is no damage and the reader is in the correct position, restart the device.

What should I do if the scale doesn't answer?

Restart the device.

What happens if I forget to remove the ventilation covers?

The device can be damaged during operation. Enter the room with protective equipment and remove the covers. If the device has been used for a long time with the outlet openings covered, we recommend having a maintenance service carried out for your safety.

What should I do if I am not sure whether the neutralization phase has ended?

If in doubt, enter the room using your personal protective equipment and check the status reports.

Questions about microbiology

_
Which microorganisms can be controlled by DISINFECT plus?

DISINFECT plus can be used against a wide variety of pathogens and unwanted germs, including bacteria, yeast, mold and viruses.

How is the decontamination cycle validated?

The validation is carried out using Geobacillus stearothermophilus spores, a non-pathogenic germ that is recommended by the RKI (Robert Koch-Institute, Berlin) as a bio-indicator.

Why can DISINFECT plus fight microorganisms so effectively?

Since DISINFECT plus produces aerosol particles that are smaller than 1 µm, these particles can attack the cell wall of microorganisms particularly effectively and destroy them by means of oxygen radicals.

Micro aerosols

_
How are the micro aerosols generated?

By energy-saving ultrasound evaporation at room temperature and a subsequent filter process that separates large particles and only blows aerosol particles of less than 1 µm (thousandth of a millimeter) into the room.

What does the air look like during fumigation?

The device blows out an aerosol mist that dissolves immediately.

Which parameters are changed?

The air humidity is influenced by the device. If necessary, a radiant heater or dehumidifier can be connected to regulate the temperature and humidity.

Are the heating elements power guzzlers? Do I need a high-voltage connection for this?

You do not need a high-voltage connection. Evaporation works via ultrasound at room temperature with a minimal energy consumption (approx. 300 watts and the fans have a peak load of up to 700 watts). Normal socket is sufficient without any problems.

Is there a sensor that measures the H2O2 – concentration? e.g. 103 H2O2/m3

DISINFECT plus has no built-in sensor for measuring the hydrogen peroxide concentration. Tests with an external sensor has shown that the H2O2 – concentration is approx. 100-120 ppm/m3.

Reagent / liquid

_
What do you measure as a concentration content?

We measure the relative humidity and thereby regulate the hydrogen peroxide content in the air.

Is the reagent listed?

Yes, our DISINFECT plus reagent is both included in the expertise list of the ÖGHMP (Austrian Society for Hygiene, Microbiology and Preventive Medicine, Vienna) and also by the VAH (Association for applied hygiene, Bonn).

Tests/studies

_
Have you tested viral pathogens?

Yes, noroviruses (hNV) and felinem caliciviruses (FCV) have been successfully tested.

In which form were the Clostridium Difficile tested: as a bacterium or as a spore?

Clostridium Difficile have been tested both in its spore form and as a bacterium.

How were the tests done?

The microbiological check was carried out at the ofi – Austrian Research Institute using ÖNORM EN 13697 and the DGHM (German Society for Hygiene and Microbiology, Hanover) methods.

Are there meaningful studies on clinical relevance already available?
