Rittal Hygienic Design (HD) Stainless Steel Enclosures

Ultimate Hygiene for Food, Beverage, and Pharmaceutical Production

Rittal Hygienic Design (HD) enclosures are tailor-made for hygiene-critical processing environments where bacterial contamination must be completely eliminated. Designed strictly following EHEDG (European Hygienic Engineering & Design Group) principles, HD enclosures withstand regular high-pressure, high-temperature washdowns with aggressive chemical cleaning agents.

Engineered Without Gaps or Dead Spaces

Unlike standard industrial cabinets, Rittal HD enclosures feature a 30-degree forward-sloped roof that guarantees complete run-off of cleaning liquids and prohibits operators from placing objects on top. The external door edges are folded back at an angle of 10° to allow water and sanitation foam to drain completely away without leaving moisture traps or pooling zones.

FDA-Compliant Joint-Free Blue Silicone Seal

The distinctive blue all-around silicone gasket is dyed blue in accordance with FDA 21 CFR 177.2600 so that any foreign particle contamination is immediately detected visually. The seal is completely continuous without joints, resists chlorinated detergents, and can be quickly replaced during routine plant sanitation cycles without requiring adhesive removers.

IP66 and IP69K High-Pressure Washdown Protection

Certified up to IP69K, HD enclosures safely endure dynamic washdown jets exceeding 100 bar at 80°C. Internal hinges and stainless steel cam locks with external hexagonal drives ensure that no threads or internal hinge pins are exposed to the open food zone, keeping production lines 100% compliant with international food safety audits (HACCP, IFS, ISO 22000).
