Walchem Water Treatment Controllers in Turkey
In Turkey, Mikron Proses supplies Walchem water-treatment controllers and analytical sensors as the Walchem (Iwaki group) distributor. Mikron Proses handles controller selection, sampling measurement-dosing panel building, commissioning, calibration and technical service.
Controller range overview
Walchem controllers cover single-parameter wall-mount units up to multi-input plant-wide systems. Current and legacy models include:
- Intuition-9 – Large-system controller with colour touchscreen (7 inch), up to 24 analog sensor inputs and up to 12 relay outputs depending on model code
- Intuition-6 – Mid-size controller with 5 inch colour touch TFT screen, 2 direct universal sensor inputs and 6 relay outputs (6 A; powered, dry-contact, or 2 or 4 opto-isolated pulse configuration)
- W100W – Wall-mount entry-level controller for conductivity and pH, universal sensor input, multiple relay outputs, large icon-based touchscreen, multi-language
- Legacy: W100P / P100 – 1/4 DIN (92 x 92 mm) panel-mount controllers; Walchem lists the series as "Discontinued with Support" (no new sales, support continues for installed units)
Legacy controllers W600 and W900 are discontinued. Mikron Proses supports replacement with Intuition-9 or Intuition-6 and keeps compatible sensors in use. The WIND (WebMaster Industrial) series is also a legacy/archive line with the same replacement path.
How to choose the right controller
| Application scale | Recommended controller |
|---|---|
| Single parameter (conductivity, pH/ORP or chlorine) | W100W / P100 class |
| Single tower or boiler needing 2 direct sensor inputs and 6 relays | Intuition-6 |
| Several towers/boilers, LPR corrosion, PTSA fluorometer and 8-12 relays | Intuition-9 |
Sensors used on W100, W600, W900 and P1000 controllers are compatible with Intuition-6 and Intuition-9. This protects existing sensor investments during upgrades.

Compatible analytical sensors
Mikron Proses supplies Walchem analytical sensors to match these controllers:
- WDS differential pH/ORP: differential technology, integral preamplifier, signal transmission up to 900 m
- WEL electrodes: cartridge-type, replaceable without removing the body; flat (PHF/MVF), bulb (PHB), low-conductivity (PHLI) or HF-resistant (PHH) cartridges
- Contacting conductivity sensors: cell constants 0.01, 0.1, 1.0, 10.0 cm⁻¹; for pure water, cooling towers (150 PSI) and high-pressure boilers (250 PSI, 205 °C)

What Mikron Proses does
As the Walchem distributor in Turkey, Mikron Proses selects, supplies, engineers, commissions, calibrates and supports these controllers. For legacy W600, W900 and WIND installations, we engineer replacements with Intuition-6 or Intuition-9 while re-using compatible sensors where possible.
Remote monitoring options include WebAlert (Ethernet/USB remote monitoring unit with e-mail/SMS alarm and Excel data logging) and Fluent cloud-based fleet management with communication via Ethernet, Wi-Fi, Modbus TCP/IP or BACnet.

Who supplies Walchem controllers in Turkey?
Mikron Proses is the Walchem distributor in Turkey. We supply Walchem controllers and sensors, engineer panels, commission systems, and provide calibration and technical service.
Are W600 and W900 still available?
No. W600 is discontinued and replaced by Intuition-9 or Intuition-6. W900 is discontinued and replaced by Intuition-9, with Intuition-6 for smaller installations.
Can I use my old W600 or W900 sensors with a new Intuition controller?
Yes. Sensors used on W100, W600, W900 and P1000 controllers are compatible with Intuition-6 and Intuition-9. Mikron Proses has confirmed this compatibility.
What is the difference between Intuition-9 and Intuition-6?
Intuition-9 accepts up to 24 analog sensor inputs and up to 12 relay outputs depending on model code, with a 7 inch touchscreen. Intuition-6 has 2 direct universal sensor inputs, 6 relay outputs, and a 5 inch screen. Choose Intuition-9 for multiple towers or advanced inputs like LPR corrosion or PTSA fluorometer; choose Intuition-6 for single tower or boiler duty.
What does "Discontinued with Support" mean for W100P/P100?
Walchem lists the W100P/P100 series as "Discontinued with Support": no new sales, but support continues for installed units. Mikron Proses supplies compatible sensors for installed units and supports replacement with current Walchem controllers; new projects use W100W or Intuition-6.
