Recommended standard dosing
The standard concentration requires 25 litres per 1000 litres of system volume, or 2.5% v/v of the overall system. At This strength most contaminated systems can be cleaned in a single operation.

We suggest sampling and analysing system fluids biannually to catch any issues early.
