The challenges of WFI controls
WFI is a significant cost factor in the manufacture of medical products and must be used sparingly for both economic and ecological reasons. Imprecise measurement methods are counterproductive. There are a number of challenges that arise during the process:
The conventional solution and its weaknesses
Precisely controlling and monitoring the WFI loop with customised systems
Reliable and efficient solutions are required to maintain, regulate and document water quality and availability in your WFI circuit round the clock. This lets you quickly respond to deviations and avoid process failures or defective batches.
The advantages of Bürkert solutions in local control loops:
Specific consultation for customised control loops
We want to ease your workload and help find your ideal solution together. That is why Bürkert supports you from the individual design of the control loop to the selection and dimensioning of the valves required in the process – including actuator technologies – all the way through to the appropriate automation solution. This means you both accelerate processes and increase system efficiency and reduce planning, start-up and operating costs. We personally tend to the selection and, if needed, pre-installation of all necessary components (valves, drive technology, pipelines) in close coordination with you.
Use our valve variant calculator to determine which valve solution is right for your WFI circuit.
Ask our experts about the ideal layout of your control loop – with automation, too.
Less energy consumption with solenoid valve technology
Power is required to create compressed air, and this is a considerable cost factor. While conventional valve technology requires a continuous compressed air supply, Bürkert’s solenoid valve technology only used compressed air when the valve position is being changed. This reduces energy consumption considerably.
Reducing operating costs with modern valve technology: Constant compressed air use in conventional valves adds up over a variety of valves and through the years.
In our sample calculation, you need 100 litres of compressed air per hour without regulation for the conventional solution. You can save on these with solenoid valve technology. Now calculate this over a period of 10 years, with 100% availability and across 30 devices, and you can save 28,000 € in this example by using less compressed air.
We have not included the costs of the low consumption of compressed air for the regulation of the Bürkert solution.
