How do hygienic process connections work?

Do you work in an environment where hygiene is very important? For example, in the food and beverage or pharma/biotech environment. Then you know that a well-designed installation is very important to prevent contamination.

Special couplings are designed to prevent contamination. In line with EHEDG or FDA guidelines, these couplings will have a low surface roughness to avoid scaling and cavities are avoided. Some applications have more specific or strict requirements than others. We are happy to help you select a connection that fits your process.



There are many different types of hygienic process connections. Some have been developed specifically for a certain application and others have been standardized. Examples are DIN11851, DIN 11864, NEUMO, VARIVENT. These types of couplings can be found in bioreactors, fermentation processes, dairy, beer and fruit juice factories. The separation membranes from Labom are loved worldwide because of their high quality.

Certain hygienic connections are also popular in single use installations, where all tubes, filters etc are disposed after production, while the electronics, instruments, controllers, hmi’s, are reused. For instance in vaccine production.
