W'eau Compact Pool automatic pH and redox control

Make maintaining your pool water a lot easier with the W'eau Compact Pool automatic pH and redox controller. This complete dosing system automatically measures and doses, ensuring that the pH and disinfection levels of the pool water are continuously monitored.

The system uses separate sensors for pH and redox (ORP). Based on these readings, the Compact Pool automatically controls the dosing pumps. When a measured value deviates from the setpoint, the required liquid is added automatically.

As a result, you do much less manual measuring and dosing, and the water balance remains much more consistent. Automatic dosing is a valuable addition to the technical installation, especially for larger pools or pools used intensively.

Automatic measuring and dosing

The W'eau Compact Pool does more than just add chemicals to the pool water. The system first checks the current water values using the included measuring probes.

Two important values are checked:

pH value: indicates how acidic or alkaline the pool water is.

Redox value (ORP): reflects the oxidation potential of the water and is used to control chlorine dosing.

When a value deviates from the setpoint, the system automatically activates the relevant dosing pump.

This ensures that dosing only occurs when it is actually necessary.

Automatic pH control

A correct pH value is one of the most important requirements for good pool water.

If the pH becomes too high or too low, this can affect the effectiveness of chlorine, swimming comfort, and various parts of the pool installation.

The W'eau Compact Pool measures the pH value with a separate pH probe. As soon as a correction is needed, pH-regulating liquid is added automatically.

This saves you from having to manually dose pH products into the pool daily.

Redox control for automatic chlorine dosing

In addition to pH, the system is equipped with a redox sensor.

The redox value is expressed in millivolts (mV) and gives an indication of the oxidizing/disinfecting power of the pool water.

When the redox value drops below the setpoint, the Compact Pool can automatically dose liquid chlorine.

It is important to note that a redox measurement is not the same as a direct measurement of the free chlorine content in ppm. The installation uses the ORP/redox value to regulate disinfection.

Much more consistent pool values

With manual water treatment, chemicals are often added in larger quantities at fixed times. This can cause water values to fluctuate significantly throughout the day.

An automatic dosing system can perform much smaller corrections when needed.

This ensures much more consistent control of the pool water while reducing the chance of unnecessarily large amounts of chemicals being added.

Digital display

On the front of the W'eau Compact Pool, there is a digital display.

Here, you can check the measured values and the system settings.

This provides quick insight into the current operation of the automatic water treatment from the technical room.

Dosing capacity up to 1.5 liters per hour

The specified maximum dosing capacity of the W'eau Compact Pool is 1.5 liters per hour.

The system also features dosing protection, which helps prevent unlimited chemicals from being added to the pool water in the event of a malfunction.

This protection is an important feature for automatic water treatment.

Calibrate first for accurate measurements

Before use, the measuring probes must be calibrated correctly.

Buffer solutions are included for this purpose.

Calibration ensures that the control unit can correctly interpret the readings from the probes. Periodic checking and re-calibration during use are also necessary to maintain reliable measurements.

Therefore, an automatic dosing system does not mean that no maintenance is required at all. The probes must be kept clean, checked, and periodically re-calibrated.

Which chemicals do you need?

For automatic disinfection, liquid chlorine based on sodium hypochlorite is used.

For pH control, a suitable liquid pH reducer is used. For this system, among others, a sulfuric acid solution of approximately 15% is prescribed.

Always use chemicals suitable for automatic dosing systems and follow the manufacturer's instructions.

Never mix chlorine and acid together. The chemicals must be stored and connected separately.

Safe installation of chlorine and acid

With an automatic dosing system, you work with concentrated liquid pool chemicals. A good installation is therefore very important.

Place the jerry cans containing acid and liquid chlorine separately, and preferably use a suitable acid- and chemical-resistant drip tray for each jerry can.

The injection points must be placed correctly in the pool piping, and the order of the various technical components must also be respected.

Especially with installations featuring a heat pump, UV-C system, or other equipment, it must be prevented that highly concentrated chemicals flow directly through sensitive equipment.

Ideal in combination with a Flow Switch

For extra safety, the installation can be combined with, for example, the Blue Lagoon Flow Switch Plus.

A flow switch checks if water is actually flowing through the pool piping. In case of insufficient flow, connected equipment can be switched off.

This is interesting for automatic dosing, as you want to prevent chemicals from being injected while there is insufficient water circulation.

Complete delivery for installation

The W'eau Compact Pool is supplied with the most important parts for installation.

In addition to the dosing unit, you receive the sensors for measuring water values, connecting hoses, calibration fluids, and fastening materials.

The liquid chemicals themselves are not included as standard.

Compact size for the technical room

As the name suggests, the Compact Pool is relatively compact.

The unit has dimensions of approximately 29 x 28 x 15 cm (h x w x d) and can therefore be neatly mounted alongside the other pool equipment.

The anthracite-colored plastic housing also ensures a neat appearance in the technical room.

What is included?

With the W'eau Compact Pool, you receive the automatic dosing unit, pH and redox sensors, connection hoses, calibration/buffer solutions, screws, plugs, and manual.

Liquid chlorine and pH-regulating liquid must be purchased separately.

Automatic water treatment for greater pool comfort

The W'eau Compact Pool automatic pH and redox controller is an excellent addition for those who want to largely automate daily pool maintenance.

The system continuously measures the pH and redox values and only doses when correction is necessary. This keeps the water values more constant and significantly reduces the frequency with which you have to work with liquid chlorine and pH products yourself.

In combination with a good filter system and possibly a Flow Switch, you can build a complete technical installation with which a large part of the daily pool water treatment is automatically regulated.
