Technical benefits - Rittal Hygienic Design

Extra cleanliness guaranteed!   Rittal Hygienic Design (HD) enclosures are key elements in the design of open processes in the food industry and clean rooms with an emphasis on ease of cleaning. Also the hygiene conditions of stainless steel cases and enclosures are decisively optimised with Hygienic Design system accessories.

30° roof tilt   30° roof tilt

The roof, which is tilted forwards by 30°, prevents objects from being deposited on it, is easily inspected, and allows fluids to drain off rapidly.

Large roof projection with overhang edge   Roof projection with overhang edge

The large roof projection with the overhang edge significantly eases pressure on the seal. It is easily cleaned, thanks to a sufficiently large gap between the overhang edge and the door.

All-round chamfered door edge folds   All-round chamfered door edge folds

All-round chamfered door edge folds contribute significantly towards ease of cleaning.

Durable all-round, external silicone seal   Durable silicone seal

The durable all-round silicone seal effectively prevents all gaps. It is easily replaced, and is clearly distinguishable from food with its blue colour.

Hinges inside the sealing zone   Inside hinges

Hinges that are inside the sealing zone create an exceptionally easy-clean design on the outside.

Stainless steel fastener and lock insert   Stainless steel lock insert and cam

The material, and in particular the shape, allow easy and reliable cleaning.

Fully sealed enclosure surface   Fully sealed enclosure surface

Fully sealed enclosure surface. This means that after machining, only essential openings remain.

If HD enclosures are used instead of stainless steel AE enclosures, there is no additional project planning work involved: The mounting plates have identical dimensions.
