Ydrokalk2 anti-limescale 20″ APC (charbon bloc), Ydro PR-YDROKALK2-20-APC

Ydrokalk 2 anti-limescale 20″ — APC (charbon bloc) media — Ydro PR-YDROKALK2-20-APC

The Ydrokalk 2 reference PR-YDROKALK2-20-APC (article code ART101393) is an anti-limescale and anti-scale system for the whole home, mounted on a « Big Blue » 20″ housing. It combines, in a single unit, sediment filtration and a multi-level anti-scale treatment, to protect pipework, boiler, water heater and household appliances without salt or chemicals.

4-level anti-scale principle

The Ydrokalk treatment works without a softener: it does not remove calcium from the water but changes the crystallisation of the limescale (catalytic/physical effect) so that scale no longer deposits on the walls. The APC (charbon bloc) media and sediment pre-filtration ensure clear water and durable protection of the network. No regeneration, no drain discharge, no salt consumption.

Composition and media

The system combines a sediment pre-filter cartridge and a treatment media: APC carbon block reduces chlorine, taste and odour and organic compounds, complementing the anti-scale conditioning. The Big Blue 20″ housing offers a high flow rate and long autonomy between cartridge replacements.

Installation

The Ydrokalk 2 installs at the home's inlet (point of entry), on the cold-water line, with a 1″ F connection. Supplied ready to fit, it mounts on the wall via its bracket and connects using the hoses and fittings available in the catalogue. Maintenance is limited to the periodic replacement of the cartridges (pre-filter + media) depending on water hardness and consumption.

Advantages

Salt-free, electricity-free (physical version) and without complex maintenance, the Ydrokalk protects the whole house against scaling: taps, heating elements, exchangers and appliances. It preserves the water's minerals (no softening), improves taste thanks to the filter media and reduces detergent consumption. An economical and ecological water-conditioning solution.

Applications

Detached houses, apartments, holiday homes, small collectives and professional premises supplied with hard water. Ideal to protect a boiler, water heater, washing machine or dishwasher, and to complement a filtration or reverse-osmosis installation. Recommended in hard-water areas to extend equipment life.

Maintenance and consumables

Maintaining performance relies on replacing the cartridges (sediment pre-filter and APC (charbon bloc) media) at the recommended interval; DIMM supplies all compatible cartridges, filter housings, wrenches, gauges and fittings. Regular visual checks of the pre-filter's fouling allow the change to be anticipated and a constant flow to be guaranteed.

Why choose DIMM

DIMM, a water-treatment specialist for more than thirty years, designs and distributes the Ydrokalk range and all its consumables. Each reference, including PR-YDROKALK2-20-APC, has a unique article code (ART101393) ensuring traceability and rapid resupply. Our teams support the choice of model (20″, APC (charbon bloc) media) according to water hardness and household flow.

Ydrokalk or softener: what is the difference?

Unlike a salt softener that exchanges calcium and magnesium for sodium, the Ydrokalk keeps the mineral content of the water and generates no salt consumption, no regeneration wastewater discharged to the drain and no brine-tank maintenance. Where the softener remains the reference for completely removing hardness, the Ydrokalk offers a simple, compact and electricity-free anti-scale protection, particularly suited to homes where installing a softener is difficult or unwanted. The two approaches are complementary and can coexist on the same network, with the Ydrokalk additionally providing sediment pre-filtration that a softener alone does not offer.

Technical characteristics

High-strength Big Blue 20″ housing, 1″ F inlet and outlet, recommended working pressure between 2 and 6 bar, water temperature from 4 to 40 °C. The flow rate suits a whole home, with reduced pressure drop thanks to the large cartridge diameter. The opaque body limits algae growth, and the reinforced head and EPDM seals are food-grade. The whole assembly is designed for use on drinking water and combines with the pre-filters, gauges and isolation valves available in the DIMM catalogue.
