Star Boiler Liquid Coagulant

Find out more

Star Boiler Liquid Coagulant is a colourless liquid sludge conditioner designed for easy feed to prevent deposits on boiler internal surfaces.

It is effective in preventing sludge deposition in boilers and will coagulate small amounts of oil which have contaminated the boiler water. The sludge is kept dispersed in small particles and conditioned to be removed by normal blow down. In this way, tube overheating due to sludge deposition is avoided.

Star Boiler Liquid Coagulant can also be used where oil contamination has been experienced, after the oil has been coagulated for removal by blown down.

The treatment can be used in conjunction with other Star International chemical treatments.


  • Liquid product, easy to feed.
  • Prevents the formation of adherent deposits and sludge in boilers.
  • Keeps sludge dispersed for efficient removal by blow down.
  • Keeps boilers clean and extends boiler operational time between cleaning


  • 25 ltrs (00950037)

Directions for use

The normal dosage will be 20ml of treatment daily for every tonne of boiler water capacity. For an average size system this will be 0.1 – 0.3 litres per day.

This level is the advised initial dosage; it can be reduced if the product is being used regularly.

For optimum results, dose Star Boiler Liquid Coagulant directly to the boiler via the by-pass pot-feeder installed in the boiler feed water feed line. It is possible to mix the Star Boiler Liquid Coagulant with water and add to the boiler hot well or add it to the boiler feed with a metering pump.

Please read the Material Safety Data Sheet before using this product for detailed information on safety and health.
