Chloromate Replacement Cells – SP & EP Salt Chlorinator Cells

Chloromate replacement cells suit SP and EP series salt water chlorinators used in Australian swimming pools. The electrolytic salt cell is the core working component of a chlorination system, converting dissolved salt into free chlorine to maintain clean, sanitised and balanced pool water.

All salt chlorinator cells are consumable components. As electrolysis occurs, the coated titanium plates inside the cell gradually wear. Over time this reduces chlorine production, even if the chlorinator control unit continues operating normally. Replacing a worn Chloromate salt cell restores chlorine output and stabilises water quality.

This collection includes genuine compatible replacement cells for:

  • Chloromate SP15 Replacement Cell
  • Chloromate SP25 Replacement Cell
  • Chloromate SP35 Replacement Cell

How a Chloromate Salt Cell Produces Chlorine

A Chloromate salt chlorinator generates chlorine through electrolysis. As salt water flows through the cell housing, a low-voltage current energises titanium plates coated with catalytic material. This chemical reaction converts sodium chloride into free chlorine, which sanitises the pool before reverting back to salt in a continuous cycle.

Because this reaction occurs every time the pump operates, the protective coating on the plates slowly degrades. This natural wear determines the service life of the salt cell.

Expected Lifespan of a Chloromate Replacement Cell

Most Chloromate salt cells last between three and seven years depending on operating conditions. Lifespan is influenced by:

  • Water balance and pH stability
  • Calcium hardness levels
  • Salt concentration
  • Chlorinator output settings
  • Daily pump run time
  • Frequency of acid cleaning

Incorrect water chemistry, especially high calcium hardness or low pH, accelerates plate degradation and reduces working life.

Signs Your Chloromate Salt Cell Needs Replacing

  • Consistently low chlorine readings
  • Chlorinator operating at maximum output with little effect
  • Increased need for manual chlorine dosing
  • Persistent warning indicators despite correct salt levels
  • Visible deterioration or plate damage inside the cell

If the control unit powers on and water flow is normal, a replacement cell typically restores chlorine production without replacing the entire chlorinator.

SP and EP Series Compatibility

Chloromate SP and EP series cells are model-specific and are not interchangeable. Each replacement cell must match the original chlorinator series and output rating. Always confirm the model number printed on your existing unit before ordering.

Water Chemistry Requirements for Maximum Cell Life

To maximise performance and extend cell lifespan, maintain the following pool balance ranges:

  • pH between 7.2 and 7.6
  • Total Alkalinity between 80 and 120 ppm
  • Calcium Hardness between 150 and 250 ppm
  • Salt level within manufacturer specifications

Only clean the cell when visible calcium scale is present. Excessive acid washing damages the catalytic coating and shortens service life.

Replacing the Cell vs Replacing the Chlorinator

In most cases, replacing the salt cell is significantly more cost-effective than replacing the entire chlorinator system. If the power supply, timer and flow components remain functional, installing a new Chloromate replacement cell restores full sanitation capability.
