WHAT IS AN AUTOMATIC DOSING UNIT (ADU)?

An automatic dosing unit is used for a variety of indoor or outdoor pools and spas. The system constantly monitors the level of chlorine and pH in the pool and adds the required amounts of chemicals to maintain the pool at the desired levels.

DO I NEED AN AUTOMATIC DOSING UNIT (ADU)?

The simple answer for commercial establishments is yes, and for private pools, it is no.

Most commercial swimming pools and spas use ADUs for various reasons. However, the main reason is the health and safety of the general public or its members.

Using an ADU means that chemicals can be dosed into the pool or spa accurately without the need for a member of staff to dose the pool or spa themselves physically.

 

As many commercial pools and spas are open early morning till late at night seven days a week, it is not safe to manually dose the pool or spa constantly to keep chemicals balanced. This is where the ADU comes into play and does all the dosing while the facilities are open.

 

Having an excellent, reliable ADU is also very important as this will save you spending £££’s extra on chemical usage.

 

Many residential pool customers in the UK like to have an ADU control the chemicals in their pools and spas as it is easier for them to manage.

 

Many private pool customers like to use a tablet feeder, which is less expensive and user-friendly; however, this type of equipment will only dose chlorine into the pool, and it will not be as accurate as using an ADU that is a tablet feeder on a private pool is more than suitable to maintain chlorine levels in the pool.

HOW DOES IT WORK?

Two tubes are plumbed into the pipework of the pool or spa filtration system; this creates a flow of water that passes through the flow cell and back into the pool or spa filtration system, or the return tube can go to a drain. When the water passes through the flow cell, the chlorine and PH sensors will detect the chemicals passing through it and message the ADU of their readings. Additionally, for an ADU to work, you will need a dosing pump for each chemical, one for Chlorine and one for Acid.

 

These pumps are connected to the ADU and will only work when the ADU signals them to dose (depending on readings). The dosing pumps have dosing lines attached to them; these lines are plumbed into the return pipework of the filtration system via chemical injectors. The controller will be set up using ‘Set Points’.

 

A basic example of this is the Setpoint for Chlorine 2.0ppm set point for PH 7.2. When the chlorine level drops below 2.0 ppm, the controller will signal the dosing pump to dose chlorine into the pool or spa until it increases to 2.0 ppm. If the chlorine is higher than the set point of 2.0ppm, the controller will not dose until the chlorine level naturally* decreases to 2.0ppm.

When the PH level goes above 7.2, the controller will signal the dosing pump to dose Acid into the pool or spa until it decreases to 7.2. If the PH level is below 7.2, the controller will only dose acid into the pool or spa once the PH level naturally* rises.

 

*In most cases, the chemicals won’t dangerously rise above or fall below-set points and can naturally correct themselves; however, sometimes, the substances may be so unbalanced that you will require assistance from Poolgenix Ltd to help balance the chemicals, especially in commercial premises.

KUNTZE NEON-MULTI WITH CLOUD CONNECT

Multi-channel water monitoring system for total chlorine, free chlorine, chlorine dioxide, ozone, or hydrogen peroxide measurement.

 

Thanks to its multi-channel monitoring, the Krypton® Multi offers precise results in industrial disinfectant applications, e.g., in drinking water plants or food production.

 

The all-in-one system consists of a measuring device, multiple simultaneous sensors, a flow fitting, software, and cables. In its basic standard configuration, the Krypton® Multi has three measurements: Disinfection, pH, and temperature. A second disinfection, redox, and conductivity measurement can also be added. There are six digital inputs for external events.

 

Eight potential-free output relays can be used either as control or alarm relays. The system features a PID controller and 3-point control functions with or without feedback.

Our modular Argon Stabiflow® fitting is integrated and provides approximately a constant water flow. Thirty litres per hour is brine resistant and approved for pressure up to 6 bar at 20 °C.

 

The Krypton® Multi can be customised to meet your measurements and control requirements.

 

With five analogue outputs, our unique Automatic Sensor Cleaning (ASR®), a Modbus RTU unit and a data logger are add-on modules.

The measurement system can be digitally controlled and seamlessly integrated into an existing measurement infrastructure via our Cloud Connect® service.

In addition, software updates and add-on modules can be activated anytime after purchase.

CHEMICAL DOSING ACCESSORIES

BUND & DAY TANKS

We offer an extensive range of day and bund tanks of all different shapes and sizes suitable for holding Calcium Hypochlorite, Sodium Hypochlorite, Hydrochloric acid, and Sodium Bisulphate.

CHEMICAL DOSING PUMPS

There are many dosing pumps, so we advise you to use good quality products that work well with your chemical controller. We work with an extensive range of suppliers, including Grundfos, LMI, and Emec; please contact us if you need any help with any spares for dosing pumps.

 

At Poolgenix Ltd, we offer a range of dosing pumps that are compatible with your dosing controller. It is important to note that when using a quality chemical controller, the dosing pumps are of fantastic quality, too.

HAND TRANSFER PUMPS

At Poolgenix Ltd, we offer hand transfer pumps and electric transfer pumps, which are typically used to transfer chemicals from 25-litre drums into day tanks for safe and ease of transferring chemicals. Pumps all come with connectors and hoses that are ready to use.

INJECTORS AND CONNECTOR KITS

If you’re looking for chemical injectors and connectors, we have many types to suit all different makes and models of dosing pumps, so if you’re looking for spares, please contact us for any help and advice so we can help you choose the correct parts.

DOSING TUBING AND OUTER PROTECTOR HOSE

We have a range of colours and sizes of dosing tubes and outer protector hoses to suit all dosing pumps.

Using colour outer hosing is a fantastic way to identify chemicals in your plant room visually. We typically use Red for acid lines, Yellow for chlorine lines, and clear for flocculant.

Our injection labels are also colour-coded to match.

WATER BALANCE TESTING KITS

Using Lovibond and Palintest as our leading suppliers, these kits offer reliable and accurate water balance testing. We offer digital and manual test kits suitable for our commercial and residential clients.

PENTAIR RAINBOW 320 INLINE CHLORINE TABLET FEEDER

Instead of using an ADU, this is ideal for private pools and spas. If you struggle to maintain your chlorine level or want a more accessible option for sanitising your pool water, this chemical feeder will benefit you. This feeder will need plumbing into the return pipework back to the pool and automatically feeds the appropriate chlorine or bromine level into the water.

 

Depending on the pool size, there is a valve/dial on the top that you adjust to control the chemical feed into the pool. All you need to do is check your water chemistry and fill the feeder. The transparent sides allow you to see the level when it requires topping up.
