Compressor assembly

Abstract

A compressor system with a water-injection cooled compressor (12) in a cooling water circuit comprises a measuring device (30) in the cooling water circuit (20) to determine the conductivity of the cooling water, a water supply source (40) to supply non-desalinated water and desalinated water, and a controlling means (70). The controlling means (70) causes the introduction of desalinated water and of non-desalinated water. The controlling means (70) causes the introduction of desalinated water, when the conductivity exceeds an upper conductivity limit, and the introduction of non-desalinated water, when the conductivity falls below a lower conductivity limit, from the water supply source (40) into the cooling water circuit (20). Thereby, the pH-value and the salinity of the cooling water are controlled such that corrosion by and deposition in the cooling water are reduced.
