UVC light

UV-light is a general term for several wavelengths including UVA, UVB and UVC. The part of the UV light that can be used for disinfection is the UVC light.

UVC light is effective and natural disinfection

It can be used to disinfect air, liquid and surfaces, and it can benefit you and your business.

Light is waves, and light can have different wavelengths. The different wavelengths are divided into intervals, including visible light, which gives us all the different colours. Some wavelengths fall under UV light, which stands for ultraviolet light, and they can be used to disinfect.

The type of UV light called UVC is used for disinfection. UVC light is very effective as a disinfectant, and at the same time, it is a natural and environmentally friendly method.

Here you can read more about how UVC light works.

This is how a UVC lamp works

When we want to disinfect with UVC light, we use a special lamp, which is made for this purpose. A UVC lamp consists of a tube which contains gas. There is an electrode at one end of the lamp, and a cathode at the other. The lamp works as follows: the electrode and cathode ignite a spark between them, heating the gas, after which the light is switched on.

If we are to create UVC light, it also requires that we work with temperature. If we take a UVC lamp and plug it directly into a socket, it will light up, but because there is nothing to control the temperature in the lamp, it will not emit UVC light. That is why our UVC lamps always come with a ballast/power supply which controls the function of the lamp. When we connect our ballast to power, the bulb lights up the way we designed it. When we design the function of the bulb, we start with the type of bulb in question and where it is to be used.

Which type of bulb can be used as a UVC lamp?

The bulb we need in a UVC lamp depends on the temperature in the room to be disinfected.

The most common bulbs for UVC lamps are mercury bulbs, as they are good in environments with a temperature around 20-30 degrees Celsius. When the ballast turns on the lamp, the gas is heated so that the mercury begins to evaporate. When the mercury has evaporated, we get UVC light.

If we need to work in other temperatures, we will experience problems with the mercury not evaporating, as it should inside the bulb, and then we will not get the UVC we want. If we, for example, have to work in lower temperatures, perhaps as low as minus 10 degrees Celsius, or in warmer temperatures, for example in production rooms reaching up to 80-90 degrees Celsius, we will instead choose an amalgam bulb, which is suitable for these temperatures.

We always check the function of the lamp before use

The UVC lamp is made of several different components, which is why it is important that we always check the setup before we use it. We do this in two different ways.

The first thing we always check is whether our lamps produce ozone. We are not interested in that, as ozone is harmful to humans and animals and our lamps are often used in places where you can find humans and animals. To measure this, we use an ozone meter, which we place in a box together with the lamp. If, after 15 minutes, there are no measurements, the lamps are free of ozone and ready to be used.

The second thing we test is whether the lamp provides the UVC light that we expect. UVC is outside the visible range, and therefore, we must measure it with the right measuring equipment to be sure that we get the desired dose.

Flexible solutions with UVC light

Using light is a very flexible way to disinfect, which can be implemented almost anywhere. We have installed our custom-made solutions at many companies, facing very different challenges.

The one thing they all had in common was that they wanted an effective and environmentally friendly disinfection method.

For some companies, the right solution is a UVC cleaning station that can clean various objects, while others need a UVC hygiene sluice that ensures access from the unclean zone to the clean zone. Whatever you need, we will find a solution that suits you and your business.
