Bacteria, viruses and fungal spores are everywhere and must be reliably killed for sensitive processes in the pharmaceutical and food industries or biotechnology. A residue-free disinfectant such as hydrogen peroxide (H₂O₂) is ideal for this purpose. To ensure that this works reliably in practice, Bürkert Fluid Control Systems has developed a scalable system for chemical disinfection with a compressed air-operated dual-substance nozzle that ensures homogeneous and fine aerosol formation with minimal chemical and energy input and thus meets the highest disinfection standards.

The wide, independent control range for air and liquid volume allows many different settings for throughput and atomization rates. This makes the system individually adjustable, very flexible and suitable for a wide range of applications such as the sterilization of packaging, Hepa filters or for room disinfection, states the company.

The liquid flow controller regulates the hydrogen peroxide, while the atomizing air is precisely metered to the nozzle at the same time via a mass flow controller.

30 to 35 % hydrogen peroxide is pumped by overpressure from a stainless-steel storage container to a liquid flow controller (LFC), which precisely regulates the amount of liquid. In parallel, the atomizing air is precisely metered to the nozzle via a mass flow controller (MFC). This takes over the atomization of the liquid phase from fine droplets to the finest mist, which then evaporates easily, adds the firm.

Due to the exact measurement of the material flows, the disinfection time can be precisely determined, which saves time. All parameters such as time duration and amount of substance can be exported and stored digitally for quality assurance, mentions the company. The disinfection system is modular and available in different versions. Depending on the customer's requirements, variants with an additional heater or integrated flushing are available in addition to the basic version with nozzle, reservoir and controllers and dosing valves with matching pipelines.
