In the late 1990’s, larger commercial type ionization units started to appear on the market.
Most of these units offered limited automation features but did include a more powerful self-adjusting output capacity of up to 100 VDC.
These larger units, normally using solid state electronic circuit boards, offer a maximum amperage output capacity of 10 to 12 amps total per controller.
One chamber cell per controller is typically used to push up to 10.0 amps depending on the VAC source (100 – 240VAC).
Amperage splitting happens when 2 or 3 ionisation chamber cells are connected to the same controller, the total controller output remains up to 10.0 amps max, yet divided into each respective cells. 5.0 amps each for 2 cells or 3.3 amps for three (3) installed chamber cells. This drop in available amperage capacity results in up to 70% lower performance with limited water treatment capacity.
Most of these older type controllers, still sold on the market today, normally require an electrical power source of 100-120 VAC (15 amps).
The solution capital cost for these older type units can range from $14,950 (USD) up to $145,500 (USD) depending on water treatment capacity requirements.
