Hygienic Design Enclosures

In hygiene‑critical environments, electrical enclosures must do more than protect components. They must also support sanitary processes, reduce contamination risks and withstand frequent washdown procedures.

Hygienic design enclosures are engineered for demanding applications where high‑pressure cleaning, aggressive detergents and strict hygiene standards are part of daily operations. Stainless steel construction, sloped surfaces, and crevice‑free design help protect electrical equipment while simplifying cleaning and maintenance.

These solutions are widely used in Food & Beverage, pharmaceutical and other regulated industries where uptime, safety and hygiene compliance are essential.

Key hygienic design benefits:
•    Design principles aligned with IP66/69, Type 4X, and food industry hygiene guidelines
•    Reduced risk of bacterial growth through smooth, drainable surfaces
•    Protection against corrosion, moisture, and aggressive cleaning agents
•    Easier and faster cleaning during routine sanitary washdown procedures
 

Hygienic design enclosure solutions for sanitary environment 

Selecting the right hygienic design enclosure depends on washdown intensity, installation requirements and the level of sanitary protection required.
Our hygienic design enclosure portfolio supports a wide range of application needs across production, processing and support areas. From zones with the highest sanitary demands to more controlled environments, each product family is developed to match the conditions under which it is installed and operated.

The portfolio brings together HDW, HDF, AFS, ASR enclosures and HDTB terminal boxes, covering different installation types and hygiene requirements commonly found within the same facility. This makes it possible to select an enclosure based on where it is used, rather than adapting the application to the product. 

•    HDW wall-mounted enclosures and HDF floor standing enclosures are used where the highest sanitary requirements apply 
•    AFS stainless steel enclosures with sloped tops address areas with regular cleaning and moderate hygiene demands 
•    ASR stainless steel enclosures and HDTB terminal boxes are typically used in controlled zones or peripheral areas
 

What is a hygienic design enclosure?

A hygienic design enclosure is a stainless steel electrical enclosure engineered to support sanitation and reduce contamination risks. Typical features include sloped surfaces, smooth finishes, hygienic gaskets and high ingress protection for washdown environments.

What is the difference between hygienic and standard stainless steel enclosures?

While standard stainless steel enclosures focus on corrosion resistance, hygienic design enclosures are specifically engineered to simplify cleaning, prevent liquid accumulation and minimize bacteria harboring areas.

Which enclosures are suitable for clean in place (CIP) or high pressure washdown?

Wall-mounted hygienic enclosures and hygienic floor standing enclosures are designed for demanding washdown and clean in place environments where high ingress protection and hygienic construction are required.

When should floor standing hygienic enclosures be used?

Floor standing hygienic enclosures are typically used when wall mounting is not possible or when larger control equipment must be housed while maintaining strict hygiene requirements.

Are different hygiene levels available for different applications?

Yes. Hygienic design enclosure portfolios typically include solutions for high, medium and basic sanitary protection levels, allowing selection based on cleaning intensity and application needs.
