Disinfection with Lechler nozzles:
Good for your health

Disinfection is about neutralizing potentially harmful material harmless so that there is no longer any risk of infection from this material. Lechler nozzles make a decisive contribution here.

The most important facts in brief

Where is disinfection necessary?

Disinfection is necessary wherever germs, viruses or bacteria occur and where these germs, viruses or bacteria can cause damage. This applies, for example, in hospitals or doctors' surgeries, but also in food production or textile care and cleaning. Disinfectants are also indispensable in normal household use.

How is disinfection done?

During disinfection, the bacterial count is brought to an uncritical level by a suitable disinfectant. In addition to the choice of the right disinfectant, attention must also be paid to the correct performance and the exposure time of the disinfectant.

What must be observed?

Common disinfectants are for example peracetic acid, hydrogen peroxide, aldehydes, alcohols and - as known from indoor and outdoor swimming pools - chlorine. All these media are dangerous products, which is why careful and well-dosed use is strongly recommended. For the correct dosage it helps to atomize the media with nozzles.

Why atomization?

Disinfectants should be atomized as finely as possible, since fine drops increase the reactive surface significantly.


Overview drop sizes and drop volumes

A large reactive surface is important to ensure that disinfectant is applied to each area and that the agent can act in a targeted manner. In addition, a large reactive surface helps to save medium, which reduces costs and is good for the environment.

Which nozzles can be used for disinfection?

Single-fluid nozzles for disinfection

To generate the necessary fine droplets for a large reactive surface, hollow cone nozzles are classically used. Depending on the required volume flow and the surface to be disinfected, different capacity sizes can be used.

The Lechler series 220 and 214/216 made of high-quality stainless steel 1.4404 are particularly suitable for the atomization of disinfectants.

Twin-fluid nozzles for disinfection

If the drops are really to be minimal, the use of two-substance nozzles is recommended. By using compressed air as atomizing medium, the liquid pressure can be kept low. Nevertheless, very fine drops and a large reactive surface are produced. In addition to surface disinfection, such nozzles can also be used for entire rooms.

For this purpose the Lechler series 136, 176 and the Lechler two-component atomizing lances are recommended.
