How the LIMex works
Proven sacrificial anode technology from shipbuilding – now for your home.
Zinc & magnesium anodes
Special sacrificial anodes release ions into the water in a controlled manner – completely harmless and drinking water compliant.
Calcite becomes aragonite
The ions convert hard, sticky calcite into soft aragonite. One zinc ion converts approx. 16,000 calcium ions.
Limescale is washed away
Aragonite crystals no longer adhere to surfaces and are simply carried away with the water.
Who is the LIMex L4 for?
- Villas and chalets with 2-4 residents
- Households with 1-2 bathrooms plus outdoor shower
- Vacation villas with seasonal or year-round rental
- Standard house connections with water hardness up to 60 °fH
- Ideal addition to an SWS reverse osmosis system for drinking water
For larger villas: 2× LIMex L4 in parallel
For very large villas with many bathrooms or a high demand for simultaneous operation, two L4s can be installed in parallel:
- Total flow rate up to 94 L/min without additional pressure drop
- Double anode surface – better treatment for high water hardness
- Redundancy – if one device is serviced, the other remains active
- Recommended for villas with approx. 6 or more bathrooms or annual consumption over 450 m³
Your advantages with LIMex
An investment that pays for itself every day.
Device protection
Boilers, washing machines and dishwashers remain limescale-free and work more efficiently.
Energy saving
Limescale-free heating elements consume less electricity. Noticeable on your bill.
Hygiene
Less limescale removes the breeding ground for legionella and biofilms.
Sustainability
Zero chemicals, zero salt, zero electricity. All minerals are retained.
Cleanliness
Fewer limescale stains on fittings, tiles and glass surfaces.
Almost maintenance-free
Zinc anodes last up to 10 years. Magnesium anodes 5+ years. No regular service necessary.
