Maintenance of Coolroom Panels

The following good practice is recommended:

  • Cleaning chemicals used for cleaning coolrooms must be compatible with COLORBOND® Intramax™ steel.
  • Cleaning chemicals used for cleaning coolrooms should only be used in concentrations and contact durations, as prescribed by the chemical supplier. In any event, the concentration of the cleaning solution should not exceed 5%.
  • Cleaning using soft nylon bristle brooms coupled with water pressures of less than 400psi (2760kPa) is recommended.
  • Regular inspection of slip joints and the general detailing of the coolroom should allow detection of problems before they become major concerns.
  • Monitoring of sealant performance at the base of the panel is critical to prevent water ingress.
  • Consideration should be given to means of preventing damage to coolroom walling incurred whilst handling stock stored within and around the coolroom.
  • IMPORTANT: Once moisture has entered the panel, it will expand if frozen, causing the panel to bulge. This may cause the seals to be broken and moisture-laden air to enter the panel, potentially causing the panel to bulge further, greatly diminishing the efficiency of the coolroom. Bulging of panels could indicate that moisture has entered the panel through the following means:
    • a poorly sealed slip joint
    • a gap that has developed between the bottom channel and the panel
    • a panel has been punctured (for example by forklift tines).
