- Decontamination liquid in particular hydrogen peroxide, is generated, which are supplied for this purpose with the decontamination liquid from the decontamination liquid container.
- WO 201 1/085735 A1 or EP 2 719 962 A1 describes a decontamination arrangement comprising a pharmaceutical isolator and an H 2 O 2 evaporator.
- the H 2 O 2 evaporator flash evaporator
- the H 2 O 2 evaporator is connected via a supply line directly to a plenum space, which is separated from an underlying manipulator space via a membrane for generating a laminar air flow during operation of the insulator.
- hydrogen peroxide vapor is introduced into the plenum via the supply line, wherein the Hydrogen peroxide vapor passes through the membrane down into the manipulator room.
- WO 2013/003967 A1 describes a decontamination arrangement in which hydrogen peroxide is not vaporized conventionally via a flash evaporator, but in which two-substance nozzles are used in order to atomize the liquid hydrogen peroxide, ie to produce an aerosol.
- a reservoir and an atomizer are an integral part of a device which can be installed as a whole in the space to be decontaminated.

The atomizer sucks in hydrogen peroxide from a pressureless decontamination fluid tank, which in turn is filled via a pump from a decontamination fluid tank. This principle is also described in EP 2 692 848 B1.

- active, ie electrical feed pumps are dispensed with in a region between the decontamination liquid container designed as a pressure container and the atomizers for conveying the decontamination liquid from the decontamination liquid container to the atomizers. This simplifies the design and control of the device or of active components considerably.
- the total amount of decontamination fluid discharged via the atomizers during a decontamination cycle can be easily determined without decontamination fluid from the at least one to have to feed a supply line back into the decontamination fluid tank.
- Another significant advantage of the invention is that due to the delivery pressure generated by compressed air critical negative pressures in the at least one supply line, at least over most of its longitudinal extension can be avoided, leading to gas bubble formation and thus possibly an uneven distribution of the decontamination on the Nebulizer or a shortage of individual atomizers can lead to decontamination fluid.

- the delivery pressure depends on the type or type of atomizer used, in particular the design of the nozzle. Some atomizers require a higher inlet or discharge pressure than others.
- the delivery pressure is dependent on whether the atomizers a valve, in particular a switching valve is arranged upstream and if so, the optimal delivery pressure in turn depends on the type of valve or the valve type. Basically, valves with a smaller flow cross section or diameter require a higher delivery pressure.

- the discretely switching switching valves in particular in the form of the aforementioned 2- / 2-way valves are preferably arranged such that between each atomizers, in particular all atomizers and the pressure vessel each such valve is and / or between the pressure vessel and at least one group of atomizers , In the case of providing a plurality of atomizer groups arranged on the pressure vessel, it is preferable to associate such a valve with each group. For optimum control and influenceability of the decontamination fluid aerosol generation, however, it is preferable to assign each atomizer its own valve, in particular a switching valve, ie a valve that can be switched between a fully closed and a fully open valve position.
- the distance of the switching valves to the respectively associated atomizer is as short as possible.
- the atomizer With regard to the specific design of the atomizer, there are again different possibilities.
