The specified limit values must always be complied with in order to avoid blockaging of the plate
heat exchanger.
Furthermore, slime-forming bacteria must be prevented in the cooling water. If this is not possible,
KKT chillers can recommend or provide an appropriate inhibitor to remove the slime forming agents
on the basis of a biological water analysis carried out in advance.
