What is it?

The AAL – CalciWave is an active electronic anti-scale device designed to help reduce limescale buildup in water pipes using a controlled electromagnetic treatment method.

Unlike passive systems, CalciWave actively generates a modulated electrical signal around the pipe via external coils, without requiring plumbing modifications or pipe cutting.

Designed for continuous operation, the system aims to influence mineral behavior in circulating water while preserving its natural mineral content.

Why did you make it?

Living in a hard-water region, I wanted a practical and non-invasive anti-scale solution for my own home.

After exploring existing systems — ranging from low-cost gadgets to expensive plumbing modifications — I found few solutions offering a practical, measurable and engineering-driven approach.

CalciWave was designed around a different philosophy: a closed-loop electronic system capable of generating and injecting a controlled and measurable signal around the pipe.

How does it work?

CalciWave operates by:

• Generating a modulated electrical signal
• Injecting controlled energy into external pipe coils
• Creating a variable electromagnetic field around the pipe
• Operating continuously on circulating water to influence mineral behavior and help reduce limescale formation

Installation is non-invasive and requires no pipe cutting or plumbing modifications.

Technical Features

• External 24V DC / 1A power supply included
  • Input: 100–240V AC, 50/60 Hz
  • Output: 24V DC / 1A
  • Region compatibility: EU plug (Type C)
  • Compatible with worldwide mains voltage. A plug adapter may be required outside EU regions.
• Approximate power consumption: ~3W
• PWM + low-frequency modulation technology
• Dual oscillator control system
• Integrated thermal protection and heatsink
• Continuous 24/7 operation
• Compatible with multiple pipe materials (copper, PEX, multilayer, etc.) and diameters

Included

• Ready-to-use CalciWave unit
• 24V power supply
• Quick-connect terminals for coils
• Installation guide

Pipe coils/wires are not included and must be prepared by the user according to the installation guide (wire length depends on pipe diameter and material).

What makes it special?

• Controlled and measurable signal generation
• Closed-loop active electronic approach
• Non-invasive installation (no plumbing modification)
• Low power consumption
• Continuous operation
• Designed with practical engineering principles rather than passive “black box” behavior

Advantages

• No chemicals
• No salt or consumables
• No plumbing modifications required
• Low maintenance
• Compatible with copper, PEX, multilayer and similar piping systems
• Preserves minerals naturally present in water

Important information

CalciWave is designed to help reduce limescale formation and influence mineral behavior in water.

It does not remove minerals from the water.

Results may vary depending on:

• Water hardness
• Flow rate
• Pipe material and installation conditions

Why this price?
