The free chlorine control system improves the accuracy of chlorine reading and regulation in Aquarite, Sugar Valley and KLX compatible equipment with optional Redox measurement.<\/p>\n

It is a solution especially indicated for pools where a more precise control of the actual free chlorine level is needed, reducing the risk of overdosing or underdosing.<\/p>\n

These kits make it possible to replace or complement the control logic based solely on ORP\/Redox with a direct measurement of free chlorine in ppm. This is especially useful in public pools, community pools, heavy use facilities or pools where water stability and compliance with disinfection ranges are critical.<\/p>\n

Advantages of free chlorine measurement<\/h2>\n

In contrast to the Redox measurement, which interprets the oxidation potential of water, the free chlorine measurement provides direct information on the concentration of available chlorine in ppm. This provides a clearer reading and facilitates a more precise adjustment of chlorine production or dosing.<\/p>\n

Direct measurement of free chlorine helps to keep the water within the proper disinfection range, avoiding both insufficient and excessive chlorine levels. This improves bathroom safety, reduces unnecessary chemical consumption and contributes to a more comfortable user experience.<\/p>\n

Amperimetric probe H-OPTION-CL<\/h2>\n

The H-OPTION-CL kit uses a copper\/gold ammeter probe to measure free chlorine. It is an effective solution for installations where a direct ppm reading is desired with a compact installation using a transparent analysis chamber with flow detector.<\/p>\n

This system is suitable for advanced private pools, community pools or installations where improved accuracy over traditional Redox control is required, while maintaining a simple and reliable configuration.<\/p>\n

Potentiostatic probe H-OPTION-CL2<\/h2>\n

The H-OPTION-CL2 kit incorporates a potentiostatic probe with membrane and electrolyte, panel mounted with prefilter. This type of measurement provides a very stable and accurate reading of free chlorine, especially recommended in installations with higher control requirements.<\/p>\n

The presence of the prefilter helps to protect the analysis chamber and the probe, favoring a more stable measurement and reducing interferences due to particles or impurities present in the hydraulic circuit.<\/p>\n

Compatibility<\/h2>\n

Compatible with Aquarite, Sugar Valley and KLX systems with optional Redox\/Free Chlorine measurement. Before installation, it is advisable to confirm that the equipment allows the addition of the free chlorine module and that it has the compatible electronics for the connection of the corresponding chip.<\/p>\n

Hayward Aquarite Free Chlorine Kit Recommended Applications<\/h2>\n
    \n
  • Condominium Pools and Commercial Pools.<\/li>\n
  • Swimming pools with intensive use.<\/li>\n
  • Installations where greater disinfection precision is required.<\/li>\n
  • Pools where chlorine overdosing is to be reduced.<\/li>\n
  • Salt chlorination systems that require direct control of free chlorine in ppm.<\/li>\n<\/ul>\n
