Stopping legionella - increasing efficiency
The precise dosing of biocides reliably prevents the growth of microorganisms in cooling circuits, ensuring long-term operational safety and efficiency in breweries.
Challenges in monitoring cooling circuits
- Open cooling systems are used in many breweries, but offer ideal conditions for the growth of legionella bacteria, which are released into the environment via aerosols and pose a significant health risk.
- Since the introduction of the 42nd BImSchV (2017), operators have been obliged to regularly monitor their systems microbiologically.
- In many cases, biocide dosing is still carried out manually, which is time-consuming and harbours sources of error.
- Irregular dosing leads to fluctuations that can impair effectiveness and jeopardise safety.
The solution from sera
The solenoid diaphragm pumps from sera enable automated and reliable biocide dosing:
- Automated biocide dosing: our systems integrate into existing cooling water systems and ensure precise, on-demand dosing of liquid biocides.
- Independent control: The integrated pump control enables operation without connection to a central process control system.
- Reliable protection: Regular dosing minimises the risk of legionella contamination.
Flexible performance classes
The solenoid diaphragm pumps are available in different versions:
- Flow rate: 1.2 l/h to 35 l/h
- Max. Max. operating pressure: 10 bar
With the automated biocide dosing systems from sera , you fulfil the legal requirements efficiently and protect your employees and your environment from potential hazards.
