Kits for carbon dioxide fertilisation in fresh water. Whimar systems are made in Italy and are all equipped with pressure reducers with built-in safety valve and fine adjustment.

The Primus series features a pressure reducer with general opening/closing knob, built-in non-return valve and outlet with fine adjustment possibility; it is also prepared for mounting high and low pressure gauges.

The cylinder supplied with the system complies with the strictest European safety standards and the needle valve from which the CO2 escapes complies with ISO EN 13340.

Il modello Complete Plus include manometri di alta e bassa pressione (per monitorare la carica residua della bombola e la pressione ci uscita della CO2) ed un’ elettrovalvola 220V che consente di impostare l’ erogazione di CO2 in base a orari prestabiliti; è sufficiente collegarla ad un timer e impostare le fasce orarie in cui si vuole immettere CO2 in vascia; ciò aiuterà a somministrare l’ anidride carbonica solo quando serve ottimizzando al meglio i consumi.
