Hygienic Design


When health and expensive resources are involved, nVent HOFFMAN has the solutions for challenging hygienic environments

Uniquely engineered enclosures are built to withstand the high-temperature, high-pressure sprays of sanitary washdown procedures, especially for clean-in-place and harsh applications. Hygienic enclosure solutions comply with harmonized global standards that indicate how well they will prevent liquid ingress, resist corrosion, and withstand temperature and pressure ranges. 

  • Design principles that pass IP69, 3-A Sanitary Standards, NSF and Type 4X 
  • Minimize risk of bacterial growth and other contaminants
  • Resist corrosion to equipment and promote longer lifecycles for controls and drives
  • Speed and simplify routine maintenance for sanitary washdown procedures
