Cooling Water (closed system)

  • Prevents corrosion and scale
  • Accurate inhibitor dosage rates
  • Reproducible, accurate results
  • Antifreeze/glycol option

Closed water systems are sealed entities, designed to distribute hot or chilled water, often as part of a manufacturing process. These systems are particularly susceptible to corrosion and scale if not properly treated. Care must be taken when selecting the measurement system/chemistry used as inhibitor dose rates are high making the aqueous environment particularly aggressive. These two closed system test kits have been specifically designed for the application and deliver reproducible and accurate results, even with highly coloured samples.
