Hygienic Design stainless steel single door wall mounted enclosures, with smooth self-draining surfaces, integrated sloping roof, silicone gasket, concealed door hinges, Hygienic Design locks and IP 66/69/69K protection degree.


The smooth self-draining sloping surfaces avoid accumulation or pooling of food product, water or chemicals. The gap-free design offers no spaces for contaminants. The high ingress protection degree allows easy and thorough cleaining with high pressure and temperature water jet, while the installed components inside the enclosure will be safe and secure.


The enclosure complies with strict hygiene standards, which reduces cross-contamination risks in industries such as food and beverage or pharmaceuticals. The high protection degree and self-draining surfaces reduce labour cost for maintenance and cleaning. Furthermore component failure and unnecessary downtime is avoided as water and dust are prevented from entering the enclosure. Stainless steel enclosures can be installed in almost any environment.
