Tips for managing soluble metal working fluid after shutdown

If you have a period of shutdown, we recommend metalworking fluid users follow the below procedure before production gets underway again.

Our Top Tips for Managing Metalworking Fluid after Shutdown

  • Skim off any tramp oil – this will allow your coolant to breathe
  • Circulate the fluid for at least an hour
  • Check dilution using a hand refractometer
    – Aim for the upper of the recommended range
    – If you’re unsure of the recommended dilution, contact our technical team who can advise
  • Top up fluid accordingly
  • Check pH level
    – If you get a low pH reading between 8.2 – 8.5 add Biotect @ 0.20% of sump capacity
    – pH readings below 8.2, a full system sterilization and fluid change is advised
  • Carry out dipslide testing
    – Refer to HSE MW05 for acceptable levels
    – Carry out full system sterilization
