Davey – tyrystorowy chlorator solny ProMatic ESR (ESR 240/300) – M1107SP

Davey – ProMatic ESR Salt Chlorinator Thyristor (ESR 240/300)

This is the genuine Davey replacement thyristor for the ProMatic ESR 240 and ESR 300 salt water chlorinator control box. The thyristor is a semiconductor power-switching component within the control unit that regulates the electrical current delivered to the electrolysis cell; when it fails, the unit typically stops producing chlorine or produces at reduced output. Replacing it restores correct chlorinator operation and avoids the cost of a full control board replacement.

Kompatybilność

This thyristor fits the Davey ProMatic ESR 240 and ESR 300 salt chlorinator models — the non-polarity-reversal variants of the ProMatic ESR range, producing up to 24 g/h and 30 g/h of chlorine respectively. It is not intended for the ESR 160/200 models (which use a different thyristor) or the ESC reverse-polarity series. Always verify your model number on the control box label before ordering.

Dlaczego oryginalność ma znaczenie

Using a genuine Davey part ensures the component meets the original electrical specification of your chlorinator’s control circuit, protecting the rest of the board and your electrolysis cell from damage due to incorrect power delivery. Please note this part is sold while stocks last and may not be reordered once depleted — if your ESR 240 or ESR 300 control box has failed, act promptly to secure this spare.

Instalacja

Replacement of a thyristor involves working inside the chlorinator’s mains-powered control box and must be carried out by a qualified electrician or authorised pool technician. Isolate the unit fully from the mains supply before opening the control box. Ensure the replacement is soldered or seated correctly before reassembly and return to service.
