HydroFLOW® K40
Experience enhanced water quality and improved filtration with the HydroFLOW® K40, your ultimate solution for addressing limescale, biofouling, and water clarity issues in swimming pools, spas, and small commercial water systems.
A Smarter Way to Improve Water Quality
The HydroFLOW® K40 enhances filtration, reduces biofouling, and helps manage limescale accumulation using patented electronic water conditioning technology. Unlike traditional chemical-based treatments, it works throughout your entire pool or water system, reducing reliance on chlorine and other disinfectants. By optimising filtration efficiency and minimising maintenance, HydroFLOW® K40 provides a low-maintenance, eco-friendly solution for commercial pools, spas, and water features.
Experience the Difference with HydroFLOW® K40
Improves Filtration Efficiency – Enhances particle removal and reduces backwashing, saving water.
Reduces Biofouling & Algae Growth – Helps keep pool water clear and balanced with less chemical usage.
Minimises Chlorine Demand – Supports healthier, more comfortable swimming environments.
Lowers Maintenance Costs – Helps reduce scaling and sediment buildup in pool equipment.
Easy Installation & No Maintenance – Simply clip onto the pipe, no plumbing modifications required.
Ideal for Apartments & Small Homes – Perfect for houses of up to three bathrooms.
Limescale is a chalky, white deposit formed by dissolved minerals, primarily calcium and bicarbonate, in water. When heated or left to evaporate, these minerals solidify and accumulate on surfaces, affecting equipment, water clarity, and the overall swimming experience.
Limescale commonly appears on:
💦 Pool surfaces and tiles – Rough deposits on walls, floors, and waterlines, making cleaning more difficult.
⚙️ Filtration and circulation systems – Blockages in pipes and filters, reducing water flow and efficiency.
🔥 Pool heaters and pumps – Scale buildup in heating elements, leading to higher energy costs and inconsistent water temperatures.
How Does HydroFLOW® K40 Improve Water Quality?
Unlike traditional methods that depend on high chlorine levels, costly chemical treatments, and frequent backwashing, the HydroFLOW® K40 offers a smarter, long-term solution. It transmits an electric field through the entire water system, causing fine particles to cluster together, making them easier to filter out. This improves water clarity while also reducing biofilm formation and managing mineral deposits.
✅ Enhances Filtration – Smaller particles bind together, improving removal efficiency.
✅ Reduces Biofilm & Algae Growth – Helps maintain cleaner, clearer water with fewer chemicals.
✅ Minimises Limescale Buildup – Helps reduce scaling in cooling towers, heat exchangers, and pipes.

FAQs
Click below to read FAQs about HydroFLOW® products.
How does HydroFLOW® work?
HydroFLOW® uses a chemical-free signal to prevent limescale buildup, biofouling, and sediment accumulation. It also gradually dissolves existing scale, improving system efficiency without altering water chemistry.
Does HydroFLOW® work on all pipe materials?
Yes, it works on copper, PVC, PEX, stainless steel, and all other piping materials.
Where should I install HydroFLOW®?
For Domestic Units:
Install HydroFLOW® on the cold water feed to the boiler, heat exchanger, or water heater for optimal protection. If this is not feasible, it can be placed anywhere between the cold water stopcock and the boiler or cylinder.
For Commercial, Industrial, and Marine Applications:
Placement depends on the specific system. In most cases, HydroFLOW® should be installed on the cold feed to the heat exchanger or key equipment to ensure maximum protection. For complex systems, consult a specialist to determine the best location.
Is it easy to install?
Yes, install it onto the pipe and plug it in - no plumbing modifications or maintenance required.
How do I know it's working?
The unit has LED indicators:
- Pearl and Pearl Plus have a rotating blue LED pattern, showing that the signal is actively being transmitted.
- K40 and HS40 have a single red LED to confirm operation.
- Commercial and industrial models have red and green light - green for power, red for signal strength.
Does HydroFLOW® require electricity?
Yes, it operates on standard mains power, using minimal energy (around £4 per year for residential units).
How long does HydroFLOW® last?
With no moving parts, units are highly durable. Residential units come with 3 year manufacturer warranty.
Commercial and Industrial units come with 3- or 5-year manufacturer's warranty, but many last over 15 years.
How does HydroFLOW® compare to water softeners?
Unlike softeners, HydroFLOW® protects the entire plumbing system without chemicals or salt, retaining essential minerals in drinking water.
Where does the dissolved scale go?
Dissolved limescale is flushed or filtered out of the system. In some cases, it settles as a fine powder at the bottom of tanks or basins, which can be periodically cleaned.
Does flow rate matter?
No. HydroFLOW® works effectively regardless of water flow rate and even treats standing water.
Will it protect my central heating system?
Yes, it prevents scale buildup in boilers, heat exchangers, and radiators, improving efficiency and longevity.
How do I see results?
Results depend on water hardness and system condition. Existing scale gradually dissolves over weeks or months, while new scale formation is immediately reduced.
What's the difference between small and large HydroFLOW® units?
Larger units have a higher power output and are designed for commercial, industrial, and marine applications.
Is the water still safe to drink?
Yes, HydroFLOW® does not change water chemistry, keeping it safe and mineral-rich.
Is HydroFLOW® covered by a warranty?
Yes, residential units include a 3-year manufacturer's warranty.
Commercial and industrial units are available with a 3-year manufacturer's warranty with an option to upgrade the warranty up to 5-years.
