Automation of the water treatment of a cooling tower:

At the heart of the measuring and dosing installation we use an EWS multifunctional controller type AS 3035 which is built into a plastic switch box, equipped with all necessary components for safe use in accordance with CE standards:

  • Conductivity measurement with control of the blowdown valve.
  • Make-up water meter pulse input for the proportional dosing of the cooling water product.
  • One time-controlled biocide dose with a spray lock for a set time during and after the biocide dose.
  • The whole is built on a plastic dosing panel equipped with two Prominent Beta4 dosing pumps, equipped with dosing valves and suction nozzles.
  • The panel is also provided with the necessary pipework with conductivity electrode and holder, flow switch, blowdown valve and the necessary manual valves.

As an extra option, a relay and connection box can be supplied in which the alarms of both dosing pumps and the flow switch are switched through.
