Bayrol Automatic Salt AS5 salt electrolysis system – Transform your pool into a self-cleaning oasis

The last time you measure pH levels. The last time you lug around chlorine canisters. The last time your children get out of the pool with red eyes.

You know the drill: Saturday, 9 a.m. Test strips in the water. pH too high. Chlorine too low. Calculate. Dose. Wait. Measure again. And all the while the question: "Is the water really safe for the children now?"

With the Bayrol Automatic Salt AS5, this chapter is closed.

The intelligent salt electrolysis system, featuring German precision engineering, automatically transforms ordinary sea salt (from as little as 1.5 g/l – less than a tear!) into gentle, natural chlorine. No pungent odor. No stinging eyes. No wasted time.

The large 4.3" touchscreen display shows you at a glance: pH value perfect. Chlorine level optimal. Water temperature 24°C. Salt content 1.8 g/l. Everything's fine – while you're grilling, not standing by the pool with test strips.

What makes it special : The AS5 doesn't just measure, it acts. Automatic pH regulation. Automatic chlorine production via electrolysis. Intelligent dosing with an alarm when the canister is empty. Integrated WiFi module for control via app – even while on vacation.

Made in Germany. For pools up to 140 m³. With Smart&Easy technology for initial setup in under 30 minutes. IP65 splashproof. Horizontal or vertical installation – you decide.

This isn't just any technology. This is the freedom to enjoy your pool instead of maintaining it.

The 5 most important advantages at a glance:

• Effective even at a salt concentration of 1.5 g/l : Gentle water like tears instead of harsh chemicals – your skin, hair and eyes will feel the difference; children with eczema benefit significantly.
• All-in-one automatic system with pH + redox + salt measurement : No separate measuring devices, no guesswork – the AS5 analyzes, regulates and produces chlorine fully automatically, you simply enjoy
• WiFi remote control via app or web portal : Control your pool from the office, on vacation, or from the sofa – receive push notifications of deviations before problems arise.
• 4.3" touchscreen with initial setup wizard : No need to wade through complicated manuals – the digital assistant guides you step by step through the setup process and provides helpful tips for status messages.
• Made in Germany with premium components : German engineering from Bayrol – every component (mechanical + electronic) is tested from the individual part to the finished product, built to last for decades, not years.

For whom is this salt electrolysis system ideally suited?

Reality check : The AS5 is for people who understand that time is the most precious commodity – and that a pool should bring relaxation, not work.

✓ Parents with children with sensitive skin
Your daughter has eczema. Your son complains of burning eyes after every bath. The harsh chlorine smell clings to his hair and skin – you can still smell it at dinner. The AS5 produces natural chlorine from salt – so gentle that it doesn't irritate mucous membranes. The water feels silky smooth, not "chemical." No need to rinse off in the shower.

✓ Busy performers with no time for pool chemistry
You work 50+ hours a week. On weekends, you want to relax by the pool with your family – not measure pH levels and dissolve chlorine tablets. The AS5 takes over the "Saturday chemist job": automatic measurement every few minutes, automatic regulation, automatic chlorine production. You open the app, see "everything green" – done.

✓ People who have once had the "green pool after vacation" nightmare
You return from a two-week vacation. The pool has gone bad. Green, cloudy water. Algae on the walls. Three days of shock chlorination, brushing, filtering – the vacation is mentally over. With the AS5 + WiFi module, you can see from Spain that the pH level is rising – and adjust it via the app. The pool is crystal clear upon your return.

✓ Tech enthusiasts with smart home
You have Philips Hue, a Nest thermostat, and smart garden irrigation. A "dumb" pool with manual chemicals doesn't fit into your system. The AS5 with Wi-Fi, app control, and real-time monitoring is the logical addition. You want data, control, and automation – not test strips and gut feeling.

✓ Wellness enthusiasts who want the "luxury hotel feeling"
You were at a 5-star spa. The saltwater infinity pool with its silky-smooth water – you stayed in for 20 minutes because it felt so good. Back home, your chlorine pool is a disappointment: rougher. More chemical. The AS5 brings the spa feeling home: naturally soft saltwater, no harsh chemical taste.

✓ Environmentally conscious pragmatists
They hate plastic canisters. Every year they buy 20-30 liters of liquid chlorine in disposable containers – which they then have to dispose of. The AS5 produces chlorine from salt: A 25kg bag of salt (paper bag, compostable) lasts for an entire season. Less packaging waste, fewer trips, less chemical storage in the garden.

✓ People with pools up to 140 m³
Your pool has a volume of 80 m³, 100 m³, perhaps even 130 m³. Many inexpensive salt electrolysis systems only manage 50-60 m³. The AS5 is designed for up to 140 m³ – with sufficient power reserves even on hot summer days with high bather usage.

✓ Premium buyers who appreciate "Made in Germany"
They don't buy no-name technology from the Far East. They want quality that lasts. Bayrol manufactures in Germany – every component is tested, from the electronics to the electrolysis cell to the finished product. That's not just marketing hype, that's German engineering standard.

Product description: When salt becomes freedom

The end of the "pool chemist job"

Imagine this: You wake up Saturday morning. The sun is shining. The kids want to go in the pool. Previously, your task would have been: test strips, measurements, calculations, dosing. Today? You open the Bayrol app on your smartphone. One glance. Everything's green. pH 7.2. Redox 720 mV. Water temperature 24°C. Salinity 1.8 g/l. The AS5 did everything overnight.

This isn't a vision of the future. This is your new reality from day one.

Salt electrolysis – The natural alternative to harsh chemicals

The Bayrol AS5 uses a principle that has proven itself in professional systems for decades: salt electrolysis .

Here's how it works (simplified):

1. They add sea salt to the pool water (1.5 to 4.0 g/l – less salty than a tear with 9 g/l)
2. The water flows through the electrolysis cell
3. Electrodes split the salt (NaCl) into its components.
4. Natural hypochlorous acid (HOCl) is produced – the most effective disinfectant.
5. After disinfection, the chlorine turns back into salt – the cycle begins again.

The result : A constant supply of fresh, active chlorine – no storage, no canisters, no pungent odor. The salt remains in the water (does not evaporate); you only need to refill it once or twice per season.

Why salt water feels better than chlorinated water

Traditional chlorine tablets/liquid chlorine : Contain chlorine in high concentrations plus stabilizers, binders, and fillers. The pH value fluctuates significantly. The chlorine is aggressively bound – it irritates skin, eyes, and the respiratory tract.

Salt electrolysis : Produces chlorine in its optimal form (hypochlorous acid) – precisely dosed, exactly when needed. The salt water has a skin-soothing effect (like the Dead Sea). No irritation, no "chlorine smell" (which, by the way, comes from chloramines = used chlorine, not from fresh chlorine).

You'll notice it immediately after your first bath : silky-soft skin instead of rough skin. No red eyes. No dry hair. This isn't your imagination – it's chemistry working for you.

All-in-one automatic system – measurement + regulation + production

The AS5 is not a simple electrolysis cell. It is a fully automated water treatment center:

Measured parameters:

• pH value (7.0 - 7.4 optimal for chlorine effectiveness and skin compatibility)
• Redox potential (700 - 750 mV = measure of disinfection power)
• Salt content (1.5 - 4.0 g/l)
• Water temperature (important for electrolysis efficiency)
• Flow rate (Safety: Electrolysis only when pump is running)

Automatic actions:

• pH too high? → AS5 automatically doses pH reducer (liquid from connected canister)
• Redox too low? (= too little chlorine) → AS5 increases electrolysis performance
• Salt level too low? → AS5 displays alarm on screen + app: "Please add 10 kg of salt"

This means : You don't have to measure, calculate, or dose anything. The AS5 does it 24/7 – more precisely than any human.

4.3" touchscreen with initial setup assistant

Many salt electrolysis systems have complicated menus, cryptic abbreviations, and incomprehensible manuals. The AS5 is different:

Large 4.3" TFT color touchscreen : Just like a smartphone. No buttons, no dials. Swipe, tap, done.

Initial setup wizard : When you switch on the device for the first time, a digital wizard guides you through the setup steps:

1. "How big is your pool?" → You type "80 m³"
2. "What salinity?" → AS5 recommends "2.5 g/l for your pool volume"
3. "Where is the pool located?" → "Outdoors" → AS5 activates temperature protection (no electrolysis below 15°C)
4. "Activate pH dosing?" → "Yes" → AS5 calibrates pH pump

The system is ready for operation after 10 minutes. No engineering degree required.

Smart tips for status messages : If the AS5 detects a deviation, it doesn't just display "Error 23" – but explains: "Salt level below minimum. Please add 15 kg of pool salt to the water and wait until it has dissolved. Then press 'Next'."

WiFi module – your pool in your pocket

The integrated WiFi module connects the AS5 to your home network. You then have two access options:

1. Bayrol Pool Access App (iOS + Android):

• Real-time display of all measured values
• Trend graphs (pH over the last 7 days)
• Push notifications ("pH value above target value – AS5 doses automatically")
• Manual control (e.g., electrolysis boost before a pool party)

2. Bayrol web portal (browser):

• Same functions as the app
• Ideal for PC/Mac at the desk
• Export data for your own analyses

Practical example : You're on vacation in Italy. Your neighbor calls: "I think your pool is getting cloudy." You open the app. You see: pH 7.8 (too high), redox 650 mV (too low). You increase the electrolysis power by 20% via the app. 6 hours later: pH 7.3, redox 720 mV. Pool saved – without a trip home.

Premium suction lance with fill level sensor (optional)

The AS5 dispenses pH reducer from a connected canister (standard: 5 or 10 liters). The problem with simpler systems is that you don't know when the canister is empty – until the AS5 sounds an alarm.

With optional premium suction lance : A level sensor in the canister continuously measures the liquid level. Display on screen + app: "pH canister still 40% full – sufficient for approx. 3 weeks." You will be notified in advance and can reorder in time.

Electrolysis cell – The heart of the system

The electrolysis cell of the AS5 (380 x 170 mm) is made of titanium with ruthenium/iridium coating – highest quality for long service life (5,000 - 7,000 operating hours = several years).

Flexible installation : Can be mounted horizontally OR vertically (Ø 50 mm connection). You decide depending on the available space in the technical shaft.

Integrated safety sensors:

• Gas sensor : Detects hydrogen formation (in case of malfunction) and switches off.
• Salt sensor : Measures salt content directly in the cell (more precise than external measurement)
• Flow sensor : Electrolysis only occurs when the pump is running (prevents overheating)

Self-cleaning function : The AS5 regularly inverts the polarity of the electrodes – limescale deposits are automatically removed. This keeps the cell cleaner for longer, increasing its lifespan.

pH dosing pump – precise regulation

The integrated dosing pump for pH minus (liquid) works with:

• Maximum flow rate: 2.4 l/h
• Max. delivery pressure: 1.5 bar

Intelligent dosing : The AS5 doesn't dispense 200ml of pH reducer "all at once" – but in small increments: 10ml, wait, measure, another 10ml, wait, measure. This prevents overdosing and ensures stable pH levels.

Dosing time alarm : If the pump runs longer than expected (e.g. because the pH value does not decrease), the AS5 sounds an alarm: "pH dosing has been running for 4 hours – please check canister and hose."

Made in Germany – Bayrol quality

Bayrol has been active in water treatment since 1927 – almost 100 years of experience. The AS5 is developed and produced in Germany.

Quality control at every step:

1. Individual part testing (each electronic component is tested)
2. Assembly under cleanroom conditions
3. Functional test of the final product (24-hour continuous run)
4. Leakage test (IP65 certification)

This means that when you unpack the AS5, it has already been tested – not just randomly, but every single device.

IP65 protection class – Weatherproof

The AS5 housing is IP65 certified:

• IP6X (first digit): Dustproof (no dust can penetrate)
• IPX5 (second digit): Protected against water jets from all directions

Practical : The AS5 can be installed in a technical shaft (where it's damp), but also outdoors under a roof. Splashing water during filter backwashing? No problem. Rain? No problem.

Dimensions: H 320 × W 210 × D 120 mm, weight 4.3 kg – compact enough for any technical shaft.

Frequently Asked Questions – Honest Answers

Q: Will the pool water taste salty?
A: No. At a salt content of 1.5-4.0 g/l, you won't taste anything. For comparison: tears have 9 g/l, seawater 35 g/l. Pool water is less salty than a tear – you won't taste it.

Q: Do I still need to buy chlorine?
A: No. The AS5 produces chlorine from the salt in the water. You only need to buy: (1) pool salt (approx. 25 kg once per season for a 100 m³ pool) and (2) pH reducer for automatic pH regulation.

Q: What are the annual operating costs?
A: Rough estimate for a 100 m³ pool: 25 kg salt (approx. €10) + 10 liters pH reducer (approx. €30) + electricity for electrolysis (approx. €50-80 at €0.35/kWh) = approx. €90-120/year. Significantly cheaper than chlorine tablets (€200-300/year).

Q: How long does the electrolysis cell last?
A: 5,000 - 7,000 operating hours. With 8 hours of filter runtime per day x 150-day season = 1,200 hours per year. The cell therefore lasts 4-6 years. After that, it needs to be replaced (replacement cell approx. €300-400).

Q: Does the AS5 also work in winter?
A: The electrolysis unit only operates above a water temperature of 15°C (protective shutdown). In winter (pool covered, not in use), switch the AS5 off or into winter mode. pH dosing can continue if the pool is heated.

Q: Do I need high-voltage electricity?
A: No. The AS5 runs on 230V household current (like your pool pump). No 400V three-phase power is required.

Q: Can I install AS5 myself?
A: With some DIY skills: Yes. The electrolysis cell is installed in the pool's piping (after the pump and filter). The control unit is mounted on the wall, sensors are connected, and the pH pump is connected. Bayrol provides detailed instructions. Alternatively: Installation by a pool technician (approx. €200-400).

Q: What happens during a power outage?
A: The AS5 saves all settings. After a power outage, it restarts automatically. The pool water remains stable (chlorine does not break down immediately). For longer outages (>24 hours), you should add chlorine manually.

Q: Can I operate the AS5 with fresh water?
A: No, you need to add salt to the pool water (at least 1.5 g/l). This is intentional – the salt is the "raw material" for chlorine production. Once added to the water, it stays there (it doesn't evaporate).
