Which substances remain after applying a compact cleaner for elim ination of smoke?

​Inside the compact cleaner model MAC the air is being sterilised, which means that bacteria, viruses, moulds and yeasts, if any, are eliminated. Also a small amount of ozone is produced which eliminates odour from the air and from the surface of the room. What comes out of the compact cleaner is mainly sterilised air and ozone.

​A residual product if any is only made in the room, after the oxidation process, as carbon dioxide and water, but in such a small amount that it will be very difficult to measure.

Therefore it is important to stress, that no foreign or harmful compounds are made. Model OZ 1000 and OZ 2000 are mainly producing ozone. They also sterilise the air as the lamps’ wavelengths in both models have a sterilising effect.​

Can rubber and electrical wires/cables be damaged if ozone is present?

​It is correct that ozone affect all organic compounds. However, there is a considerable difference whether it is a continuous influence or just a treatment. There is no risk in treating a car with the MAC/OZ compact cleaners.

​Therefore there is no risk in using the compact cleaner in offices and in private homes, as the compact cleaners are not powerful enough to fill such large rooms with high concentrations of ozone resulting in damaged cables and rubber.​

When you eliminated smell of smoke using the compact cleaners, does the smell then return?

​​The smell does not return after the treatment with the compact cleaners. Ozone has the capacity to reach all hollow spaces, carpets, behind panels etc. This means that grease and other aromatic compounds will be oxidised and it cannot return, unless there is still a source to the bad smell present.

​Therefore, it is important that a normal cleaning of the item to be treated and that the source to the smell has been removed, prior to the treatment.

If one buys a compact cleaner for the office or for private purpose, what happens if it produces more ozone that necessary?

If you feel that the compact cleaner produces too much ozone, because it basically has finished cleaning, and you forget to turn off the machine, there is no danger; it is not possible to produce a surplus of ozone with model MAC.

The smell limit for ozone is approx. 0,02 ppm. After this, the ozone begins to smell like a Xerox machine, that has copied many copies in a row. The Danish Working Environment Service has a limiting value for ozone in a working room which is 0,1 ppm. This means 20 times the amount that has to be present for smelling ozone. The MAC cannot produce enough ozone to exceed the limit set by the Danish Working Environment Service

​The compact cleaners, model OZ 1000 and OZ 2000 are more powerful models designed to ”shock treat” rooms, cars, containers etc. These compact cleaners are used to create an ozone residue in the room, and thereafter the compact cleaner has to be turned off. If these 2 models are present in the same room too long, an ozone amount can be produced exceeding the limit of the Danish Working Environment Service. We therefore recommend that no one is present in the room while treating with ozone.​

Can you eliminate the smell from mould applying the compact cleaner and if yes does this smell return after the treatment with the compact cleaner?

The smell from mould does also disappear after treatment with the compact cleaner. You cannot say that smell from mould will be gone forever, because the smell normally is transported through the air from another place than the area being treated.

Is it unhealthy to work in a kitchen where a FLO-unit is installed in the kitchen hood?

The equipment is always installed so that air is let through the extract system. In this way it is not possible to produce any ozone residue in the kitchen. It is possible to install a pressure guard on the kitchen extract system so that the FLO-unit will automatically be switched off in case of fan failure.

I have heard that it is dangerous to be in a room with ozone produced by an ozone generator. Is this correct?

​It is important to stress, that ozone is an important part of our nature and that people cannot survive without this kind of gas. However, you must also be aware that OZONE is an oxidizing agent and therefore one shall use ozone with care. As mentioned in the above there are no problems connected to the use of compact cleaners under normal circumstances.

​For 20 years Jimco A/S develops machines producing the most environmentally friendly form of ozone. The technique is based on UV-light that is developed from the ozone-producing rays of the sun. This means that only clean ozone is produced and not the form of ozone produced in high-voltage-producing units such as Xerox machines, welding units etc, where dangerous Nitric Oxide (NOX) is produced beside ozone. NOX can enter into the blood resulting in serious damage to the human body.

How does ozone remove grease from the extract system?

​Ozone “oxidises grease and oil”: This means a cold combustion that can be compared to a warm combustion.

What remains in the air after that the grease has been removed by means of ozone?

After the oxidation has been completed the end product is mainly CO2 and water together with a small amount of polymized grease, which leaves the extract system as dust.​

Is the exhaust air after the FLO-unit dangerous to the environment?

​After the process there are no compounds remaining that are dangerous to the nature. Everything contained in the end products is biodegradable.

Many books say that ozone is dangerous to animals and plants, in which way?

It is important to use ozone correctly in connection with animals and plants. Jimco A/S has gained experience in the following fields:

Breeding of fish: Here ozone produced by means of light is added to clear the water, remove coating on the tank and to eliminate diseases from fish, resulting in an improved feeding quotient. This would not be possible if using Corona Ozone (high-voltage ozone).​

Breeding of chicken: Here ozone is added through the injection ducts resulting in sterilisation of the air. The ozone also lays a protective layer on the animals, and thus minimise the danger of infection.

Greenhouses: Light produced ozone is added in greenhouses to destroy moulds and to minimise the danger of infection among the plants. However, it is important that the treatment is made in hours with day light as the photosynthesis affect the use of ozone. Also, ozone is added to the water to avoid that moulds are spread though the irrigation system

​Therefore we must point out, that ozone is not harmful to animals and plants when used correctly, in the contrary.

A clearance company I know tells that you cannot stay in a room that is being treated with ozone as it may cause skin eruption?

Jimco A/S has no knowledge of skin eruption in connection with the use of light produced ozone. It is correct, that it is recommended that no staffs is present during treating a room with ozone, using e.g. one or several compact cleaners model OZ 1000 or OZ 2000. If you stay in a room during treatment with these two models, your eyes and throat can dry out and become irritated as these machines can develop an ozone content that pass the limiting values.

​We can inform you in this connection that Danish damage service companies have started using Jimco light produced ozone due to the fact that high-voltage ozone is very dangerous to your health.

When you eliminated smell of smoke using the compact cleaners, does the smell then return?

​The smell does not return after the treatment with the compact cleaners. Ozone has the capacity to reach all hollow spaces, carpets, behind panels etc. This means that grease and other aromatic compounds will be oxidised and it cannot return, unless there is still a source to the bad smell present.

Therefore, it is important that a normal cleaning of the item to be treated and that the source to the smell has been removed, prior to the treatment.​

How do you distinguish between ozone produced in the FLO-units and ozone that is dangerous to the nature?

Ozone is a protective gas naturally present in the atmosphere. It is naturally produced by means of the ultraviolet radiation of the sun. And exactly the wavelength of the sun that produces ozone is applied in the Jimco UV-lamps.

​​The ozone that is said to pollute the nature is in fact NOX pollution and not ozone. Is a fact that NOX disturb the measuring of ozone! The best way to explain this is: Ozone smells much more strongly and characteristic. With a content of 0,02 pp you can smell the ozone (in a working room the allowed content is 0,1 ppm which is unpleasantly high). If you have a content of ozone in the nature, which you sometimes hear about in the news, it would smell heavily outside.

What happens if too much ozone is produced in the extract system?

We refer to our answer to the first question. Ozone is an unstable form of oxygen that will chemically decompose to oxygen again maximum 20 minutes after the FLO-unit has been turned off.

I have heard that the lungs might be influenced by ozone, which effect does this have on my health?

​​It is true that the lungs might be affected by continuous influence of ozone air, however it is a question of concentrations. The EU has a limit on how much ozone is allowed to be in a room, where people are present. This limit is 0,1 ppm (the same limit as the Danish Working Environment Service has set) and this is a considerable high level. Normally, there is no reason to have such a high level.

If only a small amount of ozone is present, you have a oxidation potential resulting in an improved indoor climate. We recommend using the MAC in offices and in private homes. Larger rooms can be treated with the compact cleaner OZ 1000 without danger to your health as large rooms demand more ozone for the correct treatment.

DAKK applies special UV-C lamps to produce ozone. What is the difference between the DAKK method and the ozone produced by high voltage (Corona Ozone)?

​​DAKK only produces ozone-applying UV-lamps. This means that clean ozone without any other compounds are made.

If you would apply high voltage to produce ozone, then oxygen combines with nitrogen. This means that NOX is produced contrary to ozone produced by UV-lamps – and Nitric Oxide (NOX) is an environmental problem.

​High-voltage ozone generators must therefore always be used adding clean oxygen – e.g. from an oxygen cylinder or from an oxygen generator.

However, when you produce ozone by means of UV-light you do not have the necessary energy available to produce NOX. That is the reason why the Jimco method is preferable when you care about your employees and the environment.
