Hygienic IP69K Enclosures for a Food & Beverage Processing Line

Sector: Food & Beverage / Hygienic Processing
Application: Machine and conveyor control enclosures in a washdown area
Location: Australian food processing facility

Background
A food processing plant needed to upgrade electrical enclosures in a high-intensity washdown zone. Legacy enclosures with flat tops and exposed hardware created hygiene risks and required frequent maintenance after aggressive cleaning cycles.

Challenges

  • Daily high-pressure, high-temperature washdowns demanded enclosures with IP69K protection and hygienic design features to prevent water ingress and contamination traps.
  • Enclosures had to be compatible with stainless process equipment and withstand caustic cleaning chemicals over long service life.
  • Electrical safety and compliance with IEC/EN 62208 and IEC/EN 60529 needed to be maintained despite harsh cleaning conditions.

Solution

The facility standardised on IP Enclosures’ IP69K hygienic stainless steel enclosures for the washdown area, complemented by IP66 stainless steel cabinets in adjacent lower-exposure zones.

Key elements of the solution:

  • Sloped roofs and smooth external surfaces to prevent standing water and facilitate complete drainage during and after cleaning.
  • Grade 316L stainless steel construction with hygienic hardware to resist corrosion and meet the plant’s food safety standards.
  • Carefully managed cable entry using stainless glands and hygienic fittings to maintain both IP and hygiene integrity.
  • Anti-condensation heaters in selected control enclosures to prevent moisture accumulation during cold-room cleaning cycles.

Products Used

  • IP69K hygienic electrical enclosures, stainless steel, with 30° sloping roof and smooth, self-draining body for main control panels.
  • IP69K hygienic pushbutton enclosures for local operator controls on conveyors and fillers.
  • IP69K hygienic terminal boxes for distributed I/O and sensor terminations within the washdown area.
  • SS1 / SS2 stainless steel electrical enclosures, IP66 in peripheral zones with lower washdown intensity (MCCs, remote IO).

Results

  • Significant reduction in water-related faults and ingress issues despite aggressive daily washdown, with IP ratings maintained in service.
  • Improved hygiene compliance and easier cleaning around electrical cabinets due to hygienic design principles.
  • Extended asset life and lower maintenance burden compared to legacy non-hygienic enclosures.
