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 protection degree.


The smooth self-draining sloping surfaces avoid accumulation or pooling of food product, water or chemicals. The gap-free design prevents fluids or particulates from pooling. The high ingress protection degree allows easy and thorough cleaning with high pressure and temperature water, while protecting the electrical components inside the enclosure.


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