High-precision chemical metering pumps, automated ORP/pH controllers, power drivers, and fountain manifold assemblies engineered for Swiss municipal and commercial operations.
Switzerland’s water treatment and public health governance mandates some of the most rigorous chemical control benchmarks in Europe. Facilities operating commercial swimming pools, thermal spa wellness retreats, municipal aquatics, and architectural fountain features across cantons such as Zürich, Geneva, Bern, and Valais must strictly comply with the SIA 385/9 (Society of Engineers and Architects) standards, alongside guidelines set forth by the SVGW/SSIGE (Swiss Gas and Water Industry Association).
In the Swiss alpine hydro-ecosystem, raw water often exhibits high mineral hardness and fluctuating seasonal temperatures. Traditional manual chemical addition or uncalibrated timer-based chlorine feeders fail to maintain stable disinfection levels. Over-chlorination causes harmful chloramine build-up (nitrogen trichloride), leading to unpleasant odor and eye irritation, while under-chlorination risks Legionella pneumophila proliferation—especially in heated wellness hydrotherapy pools. Automated chlorine dosers designed by established OEM factories provide closed-loop potentiometric monitoring, dynamically adjusting liquid sodium hypochlorite or inline hypochlorous acid generation to maintain free available chlorine (FAC) strictly between 0.2 mg/L and 0.8 mg/L as dictated by Swiss cantonal health regulations.
Information Gain Insight: Modern Swiss water management prioritizes "micro-dosing" chemistry—delivering continuous micro-litter injections of chlorine based on real-time Redox (ORP in mV) and pH sensors. This reduces chemical storage consumption by up to 34% annually compared to bulk pulse dosing while eliminating corrosion damage to premium AISI 316L stainless steel pool fixtures and fountain manifolds.
Integrated pH and Redox (ORP) electrodes provide continuous digital feedback to the PLC dosing unit, automatically calculating hypochlorous acid (HOCl) dissociation ratio in real time.
Factory-built pump heads utilize PVDF (Polyvinylidene Fluoride) with double ceramic ball check-valves and PTFE diaphragms, offering total resistance against concentrated liquid chlorine and acid descalers.
Equipped with standard Modbus RTU, BACnet/IP, and 4-20mA analog interfaces to seamlessly connect with Swiss building automation systems (KNX, Loxone) for centralized facility telemetry.
How OEM precision manufacturing ensures leak-free chemical dosing, long-term calibration stability, and whisper-quiet operation in Swiss facilities.
An automated chlorine dosing system functions as the neurological center of modern water filtration circuits. The process begins inside a bypass measuring cell (water sampling chamber), where water from the main filtration stream passes across glass-shielded pH and platinum/gold Redox probes at a constant flow rate regulated by an integrated flow switch. When the measured Redox potential drops below the programmed millivolt setpoint (typically 720 mV–750 mV for Swiss commercial pools), the micro-controller signals the metering pump.
In Swiss luxury residential and boutique hotel spa installations, peristaltic dosing pumps are frequently preferred due to their whisper-quiet operation (<35 dB) and self-priming capability without off-gassing vapor lock. For large-scale public aquatic centers and high-volume commercial fountains, heavy-duty solenoid diaphragm pumps or motor-driven diaphragm pumps are deployed to deliver high injection pressures up to 10 bar against main line hydraulic pressure.

From alpine altitude thermal pools to urban commercial plazas, tailored chemical dosing solutions engineered for distinct environmental requirements.
High-altitude thermal waters (e.g., Zermatt, St. Moritz) require rapid compensation for temperature drops and mineral outgassing. Automatic dosers prevent scale deposition while stabilizing disinfection in hot water up to 38°C.
Heavy bather loads require high-capacity, dual-redundant chlorine dosing skids. Continuous telemetry logging ensures data compliance with municipal health department inspections.
Plaza fountain features use low-noise automatic dosers integrated into IP67 outdoor stainless steel control cabinets, protecting stainless steel spray ring manifolds from biological bio-film buildup.
Estate owners demand compact, wall-mounted dosing stations featuring smartphone Wi-Fi/Ethernet connectivity, allowing remote monitoring during winterization or extended travel periods.
Combining over 20 years of OEM production heritage, ISO 9001 certification, and complete turnkey electrical-hydraulics expertise.
As a specialized manufacturer with two decades of experience and over 1,500 completed global projects, our production facilities engineer complete turnkey water treatment solutions. Unlike mere trading intermediaries, we manufacture core components in-house—including custom stainless steel control cabinets, high-precision nozzle manifolds, programmable PLC control logic, and underwater electrical lighting drivers.
Every automatic chlorine doser undergoes 100% factory hydrostatic pressure testing, electrical isolation checks, and multi-point calibration verification prior to export dispatch.
We tailor panel layouts, dosing outputs, language interfaces (German, French, Italian, English), and private-label casing designs to meet Swiss distributor specifications.
Our engineering team coordinates chemical dosing with sand filtration pumps, reverse osmosis purification units, UV sterilizers, and DMX fountain controllers seamlessly.
Clear, authoritative answers addressing local standards, installation, calibration schedules, and chemical compatibility.
SIA 385/9 regulates water treatment systems for public swimming pools in Switzerland, mandating precise limit maintenance for free active chlorine (0.2–0.8 mg/L), pH values (6.8–7.6), and maximum combined chlorine (≤0.2 mg/L). Factory-grade automatic dosers satisfy these criteria by utilizing dual-channel potentiometric measurement cells with temperature compensation, continuous flow sensing, and automated safety cut-off alarms to prevent chemical over-dosing.
Yes. Our metering pumps feature chemically inert PVDF heads, PTFE diaphragms, and Hastelloy/ceramic check valves optimized for commercial-grade liquid sodium hypochlorite (12–15% NaOCl). For calcium hypochlorite slurry systems, specialized peristaltic dosing units with anti-crystallization peristaltic tubing are deployed to prevent valve clogging.
Given the moderate to high mineral hardness of Swiss municipal supply water, glass electrode probes should undergo buffer solution calibration (pH 4.01 / pH 7.00 and 468 mV Redox standard) once every 30 to 60 days. Automatic dosing controllers include single-point or two-point digital wizard calibration options to simplify routine maintenance for site operators.
Absolutley. Factory controllers offer native RS485 Modbus RTU, BACnet, and 4–20 mA isolated analog outputs. This allows facility managers in Zurich, Geneva, or Lugano to view real-time pH, ORP, chemical tank levels, and alarm status directly from their centralized BMS dashboard or KNX home automation setup.
For outdoor commercial pools or ornamental water features in alpine regions like Zermatt or Moritz, liquid chemical lines can freeze if unheated. Factory dosing skids installed outdoors are mounted within insulated, IP65/IP67 rated, thermostatically heated stainless steel control cabinets. During seasonal shutdowns, automated line-purge modes allow operators to flush lines with clean water effortlessly.
Standard model orders are typically assembled, calibrated, and dispatched within 7–12 business days. Express air freight to Zurich (ZRH) or Geneva (GVA) airports takes approximately 3–5 days, while standard sea/rail freight routes deliver to Swiss regional hubs within 20–28 days.
Yes. As an OEM factory supplier, we maintain a complete inventory of replacement peristaltic tubes, PVDF pump heads, ceramic valve balls, injection valves, suction lances with foot valves, and pre-calibrated pH/Redox electrodes for rapid international dispatch.
