After years of requests for greater mobility for our industrial systems, we have finally found the perfect products.
Discover our new range of portable professional RO systems. Simply connect this cart-mounted system to a water supply hose, and you can easily produce 100 to 200 l/h (depending on feed water quality) of RO water, or even fully demineralized water if needed. We have also developed a 230V plug-in version with a demineralization option so you can produce even purer water.
Consumable Service Life
Estimates provided by the manufacturer
The service life of consumables depends in particular on feed water quality, conductivity, hardness, and how often you use your RO system.
| Consumable | Estimated Service Life | Conditions |
| Membranes | ≈ 2 years | With regular use of approximately 20 h per week and under normal conductivity and hardness conditions. |
| Sediment pre-filter (PP) | 10 to 20 m³ | Depending on feed water cleanliness. |
| Activated carbon filter (CTO or GAC) | 10 to 20 m³ | Depending on the free chlorine level in the water. |
| Amberlite resin | ≈ 20 m³ | Depending on the purity of the water produced, feed water conductivity, and membrane age. |
Keep in mind: these values are manufacturer estimates. Actual consumable service life may vary depending on the quality of the water treated and the system’s operating conditions.
