Calcium Hypochlorite - Melclorite Logo

Not all Calcium Hypochlorite is the same, and when considering different products you should include in your evaluation the following factors :-

  • Available active chlorine
  • Insoluble material
  • Water content


Why? well for the following reasons:-

The more active chlorine the less product is required to maintain free chlorine

The less insoluble material then the less blockages, contaminants and maintenance costs, reducing operating costs.

The more water content the safer the product, as the lower the water content the more risk there is of flammability.


Melclorite boasts 70->75% available chlorine (10-15% more than any other brand)

Melclorite is manufactured in Japan with a patented process and has 3 to 5 times less insolubles
