Walchem W900 Series Controller

The Walchem W900 is a multi-parameter water treatment controller that has been discontinued; it has been replaced by the Walchem Intuition-9. The Intuition-9 does the same work with wider input and output capacity. For smaller installations the Intuition-6 may be suitable. As the Walchem distributor in Turkey, Mikron Proses (Üsküdar, Istanbul) supplies sensors for existing W900 installations and provides application consulting for the move to a current controller.

If you are looking for a W900: the Intuition-9 replaces it

The Walchem W900 series is no longer manufactured. Its successor, the Walchem Intuition-9, covers the same applications with a larger input and output capacity. Smaller installations may use the Walchem Intuition-6.

You do not need to replace your sensors

Mikron Proses has confirmed that sensors used with W100, W600, W900 and P1000 series Walchem controllers work with the Intuition-6 and Intuition-9. When a controller is renewed, the investment in sensors does not have to be repeated, which is a frequently asked cost question in a changeover.

Which model to move to

The choice depends on the number of parameters you measure, the sensor types and your existing automation. The W900 is used for cooling tower chemical control, boiler feedwater and blowdown management and automatic disinfectant dosing; see the cooling tower automation guide and the Walchem brand page for background.
