Cooling Water/LPHW/Chilled (Closed System) - Test Kit 4

Mark as favourite

Part Number 56K000601


  • Complete analysis kit including Molybdate, Iron and Conductivity
  • Prevents Corrosion and Scale
  • Accurate inhibitor dosage rates
  • Reproducible, accurate results

Re-circulating cooling water requires carefully chosen chemical treatments. This helps to minimise microbiological contamination, scaling of critical parts such as heat exchangers and to prevent corrosion.

To be most effective, treatments must be maintained within specific control parameters, as excess inhibitor can have as detrimental an affect as too little.

  • Cooling Water
  • Drinking Water Treatment

  • Waste Water Treatment

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 does rates are high, making the aqueous environment particularly aggressive.
