Is Nocotech's dry disinfection effective?

Nocotech is an automated disinfection system consisting of a machine; e.g., a Nocomax, and liquid; Nocolyse Food liquid containing 7,9% H₂O₂ (hydrogen peroxide). Together they make a dry disinfecting vapor.

How does that work?

Through the ultra-speed turbine in the Nocotech machine, ionized air is created and blown out of the machine at a tremendous speed. The ionized air is further heated along the way to enhance oxidation with the liquid. During the process of blowing out the ionized air, a few milliliters of Nocolyse Food liquid is added to the ionized air through a venturi effect. The molecules of the Nocolyse Food liquid disintegrate when they come into contact with the "static" heated air.

Then the liquid takes on a "gaseous" form, consisting of OH¯ ions. It has become a dry vapor, a cloud of ions. The ions fill the entire room, from ceiling to floor and everything in the room. The property of ions (charged particles) is that they want to oxidize with anything organic. So also microorganisms. And not a few types of microorganisms, all types of microorganisms.

As a dry vapor, the hydrogen peroxide (H₂O₂) is as much as 16 stronger than in liquid form. So no microorganism can withstand it.

The advantage of the dry ion vapor is that it reaches all places in the room. So e.g. also the underside of a workbench, a conveyor belt or in an evaporator.

Another advantage: H₂O₂ in liquid form is an excellent disinfectant, but has the disadvantage of being highly corrosive on all metals. As a dry vapor, H₂O₂ is as much as 16 stronger than in liquid form. And then has the advantage that it also loses its corrosive property after the molecules disintegrate. Metal, switch boxes and any other surface are not affected at all.

And furthermore, it is nice that no unwanted residue is left behind. So rinsing is unnecessary. That makes a huge difference in water consumption and is better for preserving the machines in the production area.

Effective?

Nocotech was originally developed for the medical industry but in the Netherlands it is mainly used in the food industry. There, disinfection takes place on a daily basis. And actually that is a preventive disinfection to keep the infection pressure as low as possible. As long as the reduction of Nocotech treatment is stronger than the increase of microorganisms during a production day, the infection pressure decreases. In practice, we see that the minimum dosage is enough to achieve good results. That minimum dosage is only 1 ml/m³. But how effective is it when you start measuring it in a laboratory?

This has been studied by Nutrilab.

Results test.

The Nocotech method has been tested by several independent laboratories on a number of types of microorganisms. It is interesting to know, how big the reduction is with a dosage of 1 ml/m³, as used in the food industry. Herewith some test results performed by Nutrilab. In the 1^e column are the types of microorganisms, in the 2^e column are the initial values. These are the infections per species. The following 3 columns show the reduction of 1 treatment each.

A substantial reduction was measured for each species. Obviously, a laboratory setup is the optimal situation but it indicates that Nocotech is a very effective method of disinfection.
