PFLITSCH Hygienic Design solutions –
a comprehensive portfolio for safe processes

Hygiene is increasingly being seen as an absolute top priority in the food and pharmaceutical industries. This explains why the manufacturing process and production facilities are the subject of ever greater demands in this regard. As a pioneer in the field of Hygienic Design, we pursue a holistic approach. The result is a smart system of coordinated cable entry, cable routing and cable protection solutions that meets the standards laid down for hygienic production plants. This system enables you to meet the future challenges in respect of hygiene and comply with the highest standards.

What is Hygienic Design?

In a word, Hygienic Design describes the easy-to-clean design of parts, components and production facilities. In hygiene-critical production environments, the prevention of microbial and particulate contamination of products is a key requirement. Geometric equipment design and the choice of suitable materials have a decisive influence on the suitability for clean production.

The right solutions for every product zone

Food production plants have different zones with different hygiene requirements. In general, the closer the contact system components have with the food products, the higher the hygiene requirements.

PFLITSCH offers a portfolio of solutions that are precisely tailored to the specific requirements.

Product contact zone

In this zone, food can come into contact with parts of the plant and then return to the manufacturing process. For this reason, the hygiene requirements are particularly high here and the components installed must not aid the formation of potential dirt traps. It is precisely such zones that led PFLITSCH to design its product solutions in accordance with the Hygienic Design guidelines of the EHEDG.
The use of high-quality materials that are resistant to cleaning agents plays an important role, as does an adapted design without corners and edges that facilitates cleaning.

Splash zone

In the splash zone, food may come into contact with system components and accumulate there. Easy, hygienic cleanability of the system is therefore essential.
To prevent food sticking, the components must be protected or have smooth surfaces to enable residue-free cleaning of the production sections concerned so that no bacteria nests can form here either.

Product-free zone

Away from the actual food processing, the requirements in this area are comparable to those in a standard industrial environment.
As the food in this area is already packaged, there is no risk of contamination. However, depending on the application, it can still be advisable to use Hygienic Design products from PFLITSCH here.

Hygienic cable glands

Cable glands used in the food industry must meet both basic and highly specific requirements. We have developed our own product ranges based on the tried-and-tested blueglobe cable gland for demanding hygiene applications in the food industry: blueglobe CLEAN Plus and Cleanplus. These combine the well-known strengths of PFLITSCH cable glands with a design tailored to use in the food industry.

CABseal clean

For hygiene-critical areas in the food industry, PFLITSCH offers the CABseal clean, a splittable cable entry and transit for pre-assembled and non-pre-assembled cables and wires. The hygienic design facilitates easy-to-clean installation and simplifies the safe insertion of cables with connectors. The frame, made from 1.4404 (AISI 316L) stainless steel, FDA-compliant materials and special hygienic screws, is designed to meet the requirements of demanding hygiene applications.

Wire-tray Trunking

Cable routing in the food industry also poses special challenges. The entire cable routing systems are considered with regard to the strict hygiene regulations in the food industry. A key aspect is cleanability. Our open Wire-tray Trunking system, optimised according to Hygienic Design principles, is the perfect solution for clear cable routing, offering variability, durability and great stability. The construction, made from stainless steel wires, allows for flexible routing tailored to the specific plant layout.

Cable protection

In the food industry, cables are exposed to mechanical stress, temperature fluctuations, chemicals and cleaning agents. We offer a perfectly coordinated cable protection range of hose solutions and cable glands to support smooth production processes. Different pressure hoses and a sheathed corrugated conduit are available that are tailored to the application in question. They are temperature-resistant, easy to clean and compatible with the blueglobe CLEAN Plus and Cleanplus cable gland.

With the Cleanplus TRI, PFLITSCH offers a unique solution for applications in which, in addition to the highest level of hygiene safety, absolutely reliable EMC protection is essential. This is ensured by the proven and patented TRI spring, which is already successfully used in the blueglobe TRI and UNI Dicht TRI models. The Cleanplus TRI enables full-surface shield contacting (method) with outstanding shield attenuation values and offers certified hygiene safety in accordance with the hygienic design guidelines of the EHEDG.

The Wire-tray Trunking in practical application: Rothaus brewery

PFLITSCH cable trunking routing at a Rothaus beverage bottling plant

The Badische Staatsbrauerei Rothaus AG, producer of the well-known Tannenzäpfle beer, needed to route cables for a new bottling plant. The requirements: hygienic, safe and clear cable routing. The brewery ultimately opted for Wire-tray Trunking from PFLITSCH, not least because of its stability and corrosion resistance. But the customer was also convinced by the installation enabling an individual cable layout. For maximum hygiene, in some process areas parts of the Wire-tray Trunking were even welded with the covers. The Rothaus brewery has relied on our Wire-tray Trunking for 10 years already and has even obligated its suppliers to install it.

Tested safety for cleanroom applications

The Fraunhofer cleanroom listing provides users with reliable guidance when selecting suitable products for controlled and particularly sensitive production environments. CABseal clean is now officially listed in the Fraunhofer database: The cable entries and transits have been tested for particle emission in accordance with ISO 14644-1 and ISO 14644-14 and have achieved ISO Class 1 air cleanliness. CABseal clean thus provides a certified basis for the safe and reliable routing of cables through cleanroom walls – particularly where the highest standards of cleanliness and process reliability apply.

Certifications – safety signed, sealed, delivered

We set high standards for our solutions. Take the blueglobe CLEAN Plus, which was the world’s first cable gland to be developed according to Hygienic Design principles and certified by the EHEDG (European Hygienic Engineering & Design Group). Its successor, the Cleanplus, has also been certified in accordance with the EHEDG’s principles, albeit in accordance with the new, stricter requirements. Like many other products in our range, it too is FDA-compliant and has proven its outstanding hygienic design in numerous tests. For example, its resistance to cleaning agents and disinfectants has been successfully tested by the Ecolab laboratory.
