Swimming Pool Purifiers
Filter and sort
What is a pool filter system and what is it used for?
A pool filter system is the combination of pump + filtration hydraulics that ensures water recirculation to keep it clear and safe. We offer solar solutions (Lorentz PS2 with integrated MPPT; ZIRI FCP/XKP), hybrid (solar with 230 V single-phase backup), and AC (230 V single-phase or three-phase 230/400 V). Note: Lorentz PU units without controller (e.g., PU600 CS-17-1, PU1800 CS-37-1) are listed under spare parts.
Advantages and limitations
- Efficiency: the solar option reduces consumption and operates preferably during hours of highest irradiation.
- Flexibility: hybrids switch to 230 V single-phase when solar radiation does not cover the flow; pure AC available in 230 V single-phase and three-phase 230/400 V.
- Reliability: sealed motors, MPPT/press-control, and protections against dry running.
- Limitations: incorrect sizing can cause low water renewal; it is necessary to account for losses in filters/pipes and keep clogging under control.
Applications
- Residential and community pools (12–36 m³/h).
- Recreational facilities and pools with daytime demand.
- Off-grid systems with compensation tank and priority solar operation.
How to choose your filter system
- Pool volume (m³) and desired turnovers/day (usually 1–3). Flow rate ≈ volume / operating hours.
- Total Manometric Head (TMH): sum of height + losses from filters, pipes, valves, and fittings.
- Energy: solar (PS2 includes MPPT), hybrid (backup 230 V single-phase) or AC (230 V single-phase/three-phase 230/400 V).
- Compatibility: pipe diameter, filter connections, and water quality; use suitable filters/strainers.
Indicative specifications
| Typical flow rate | 12–36 m³/h (depending on model and pool size) |
| Manometric head | 9–27 m (considering losses in the filtration circuit) |
| Power supply | Solar MPPT | Hybrid (solar + 230 V single-phase) | AC (230 V single-phase / three-phase 230/400 V) |
| Control | MPPT/variable speed drive, timer, press-control, level probes (depending on configuration) |
| Protections | Dry run, thermal, DC/AC overvoltage, check valve |
| Key accessories | Pre-filter/strainer, pressure gauge, valves, PV protections, AC panels |
Best practices
- Calculate the required flow rate based on turnovers and available solar hours (for solar/hybrid).
- Size pipes and filter to keep losses contained; clean the pre-filter and monitor clogging.
- Schedule daytime operation; for hybrids, configure switching to 230 V single-phase correctly.
- Include protections: PV isolator, overvoltage, circuit breaker/RCBO, and dry running if supplied from a tank.
