Simplex R-evolution Water Softener: the first and best-selling range of hydrodynamic water softeners
The Simplex R-evolution range from Manta Ecologica offers hydrodynamic water softeners without electricity, compact and extremely efficient.

For over twenty years, Manta Ecologica has revolutionized the water treatment market with the Simplex R-evolution line, the first and best-selling range of hydrodynamic softeners in Italy. An advanced, compact and electricity-free technology, designed to drastically reduce consumption, simplify maintenance and ensure maximum efficiency in protecting systems from limescale build-up.
The invisible problem of limescale: damage, waste and regulations
The presence of limescale in drinking water is one of the main causes of inefficiency in domestic and professional systems. Just one millimeter of scale is enough to reduce boiler efficiency by 10%, with a direct impact on energy consumption ( +20% ) and on the annual expenses of an average family. In addition to the economic damage, limescale compromises the life of household appliances and taps and promotes bacterial proliferation. For this reason, the UNI 8065:2019 regulation requires its elimination through softening in the presence of hardness greater than 15 °f and thermal power over 100 kW.
Simplex R-evolution: hydrodynamic technology without electricity
The Manta water softeners of the R-evolution line are completely hydrodynamic : they do not require electrical power, do not contain electronic components and do not require any programming. This translates into greater reliability over time, less maintenance and the possibility of installation even in environments without electricity. Making the solution even more advantageous are:
- Rapid regeneration : only 15 minutes compared to the market average of 90 minutes.
- Optimized consumption : 90% less water and salt for each regeneration.
- Small footprint : up to 80% less space than conventional water softeners.
A complete range for every plant engineering need
The Simplex R-evolution line is made up of models designed for every application context:
- Simplex 330/SMC : compact, ideal for homes of up to 4 people. Flow rate of 1.5 m³/h.
- Simplex 2500/SMC/A: for domestic or light industrial use. Flow rate up to 2.7 m³/h.
- DUPLEX 330/DA and DUPLEX 4000/DA: double-body water softeners with alternating regeneration, designed for 24/7 service continuity.
- R-evolution modular systems: from 4 to 8 cascade modules, for condominiums, hotels and industrial plants with flow rates up to 20 m³/h.
Each model is automatic, volumetric and designed to ensure maximum efficiency and ease of installation.
Real savings, measurable benefits
In addition to energy savings and reduced maintenance costs, installing a R-evolution water softener allows you to reduce the use of detergents and chemicals by up to 50%, with positive effects on environmental sustainability. Manta technology allows for a rapid return on investment , thanks to operational efficiency and the absence of electricity costs or electronic spare parts.
Manta Ecologica's experience in support of professionals
In addition to the quality of its products, Manta Ecologica supports installers and designers with training tools and technical content that is always up to date: in-person training courses in Verona, throughout Italy and online, video tutorials, technical notebooks, blogs and guides dedicated to water treatment. With over 40,000 installations in Italy, the R-evolution line is confirmed as a proven professional choice, ready to meet the needs of modern heating and plumbing systems.
