The maximum concentration levels that should be used during a CIP for acid is 0.8% and for caustic it's 1.5%. Any greater level does not provide an increased benefit in terms of cleaning the system, it is purely wasting chemicals. Excess levels will also adversely affect other parts in the system, such as seals and gaskets.
AVOID THE FOLLOWING:
- Peroxyacetic acid and Sodium Hypochlorite as it is extremely harsh on rubbers, gaskets and seals, including the urethane of BFM® Seeflex connectors. If required, do not use in high concentrations or with temperatures over 45°C/113°F as it is too harsh.
• Washing in water over 100°C/212°F or exposing to direct steam.
See our guide to manual cleaning of your BFM® connectors.
Whilst there is potential for CIP chemicals to get into the internal gap during CIP, the BFM® fitting is still far superior to any other type of connector in this situation. We always recommend the BFM® connector is removed and wiped clean after the CIP process to ensure no residual chemicals.
