When to replace the resin filter

The ion-exchange resin polisher keeps feedwater conductivity within the PEM stack's operating window (TDS ≤ 5 µS/cm). As the resin saturates, conductivity drifts up and stack efficiency falls. Replacement intervals vary with operating hours, ambient temperature and the purity of refill water; most vehicle applications fall in the 6–9 month range.

  • · Replace if the high-TDS alarm is triggered
  • · Replace at every scheduled service interval
  • · Use only deionised / purified water for refills
  • · Keep one spare on the vehicle for fleet operations
