Cintropur TRIO UV 40 W (UV 4100) – complete water treatment with pre-filter, activated carbon and UVC disinfection
Cintropur TRIO UV 40 W is a compact, proven 3-in-1 solution for houses and small businesses that want safer and more pleasant water quality from rainwater, wells/boreholes, cottage facilities or as extra security for municipal water. The unit combines cyclonic mechanical pre-filtration, reusable container for coconut-based activated carbon and UVC disinfection at 253.7 nm in one service-friendly cabinet. The result is an effective reduction of particles, improved taste and smell, and inactivation of bacteria, viruses and protozoa - without chemicals and without changing the water's natural properties.

Why Cintropur TRIO UV 40 W
This model is designed for real household flow and easy operation. The pre-filter rotates the water and captures coarser particles before fine filtration with a sleeve, then the water passes through a refillable charcoal container for sensory enhancement, and finally into the UVC reactor (40 W) for physical disinfection at 253.7 nm. Prefiltration before UVC is essential because turbidity and particles can shield microbes; The TRIO setup solves this in the same system.

Health effects
• 🔒 Chemical-free, physical disinfection that can contribute to safer, more comfortable use in the shower and kitchen.
• 👃 Improved taste and smell through adsorption in coconut-based activated carbon.
• 🌫️ Reduced particle load (sand, rust, soil) via cyclone and sleeve sleeve.
• 💧 Support for stable water quality in case of varying raw water, especially for rainwater and own water supply.
• 🧰 Service-friendly, modular system that can simplify maintenance and operating costs.

Top features
Cintropur TRIO UV 40 W is most often used to deliver water with improved sensory quality and to provide a robust, physical UVC barrier against microbiological deterioration throughout the house. A further strength is that the reusable coal container provides low waste and the flexibility to adapt the type of coal to special needs.

A lesser known benefit
The reusable carbon container (CTN) can be refilled with loose bulk of high-quality activated carbon. It reduces single-use plastics and makes it possible to optimize the treatment against specific flavors or selected micropollutants, while preserving the hydraulics in the system.

Areas of use
The product is suitable for detached houses and cottages, small multi-dwelling buildings, water points in HORECA, cultural and sports buildings, water coolers and aquariums, as well as "point-of-entry" where a complete, physical treatment line is desired. For rainwater, the TRIO configuration expands the field of application by handling particles, dissolved organic substances (sensors) and microbiology in the same unit.

This is how the system works - step by step
Cyclonic pre-filter creates a centrifugal effect that precipitates coarse particles at the bottom of the bowl before fine filtration in sleeve sleeve with selected fineness, usually 25 µm in the TRIO set-up. Activated carbon in a refillable container adsorbs chlorine, ozone, taste and smell as well as a number of organic micropollutants. The UVC reactor with a 40 W low-pressure lamp irradiates the water at 253.7 nm; dosage (mJ/cm²) is determined by lamp power, contact time and the water's optical properties (UV transmittance).

Performance and correct sizing
To preserve the disinfection effect, the water should be clear and low turbidity. Good practice is low turbidity and high UV transmittance (typically ≥90% at 1 cm) after filter and charcoal. In operation, you should keep the real flow below the nominal maximum when the water is less clear, and reduce the flow when UV transmittance is reduced, for example during heavy rainfall in rainwater systems.

Technical details and specifications
The unit consists of pre-filter (cyclone and sleeve), refillable container for activated carbon and UVC reactor. All wet materials are in certified, potable synthetic material with O-rings in the head for secure sealing. The UVC lamp is a low-pressure lamp that emits at 253.7 nm; the recommended lamp change is once per year, and the quartz sleeve is recommended to be changed every five years. Bayonet socket with approximately 5° twist allows quick service replacement. The connections are ¾″ and 1″. Nominal maximum flow is up to approximately 2.6 m³/hour when pretreatment and UV transmittance are satisfactory. The pre-filter uses sleeves in various finenesses (usually 25 µm in TRIO), and coarse particles are collected in the bottom chamber which can be drained. Activated charcoal is coconut-based and suitable for sensory enhancement; the container is easily filled during service. Operating tips include annual lamp change, inspection and cleaning of quartz if necessary, periodic top-up of activated carbon after load and replacement/rinsing of sleeve sleeve in case of differential pressure or visible siltation. The UVC section must always be installed last in the treatment line.

Installation and security
Place the unit accessible for service, with shut-off valves and relief. Install on a firm surface and follow the installation and electrical instructions. Mercury lamps must be delivered to an approved reception in case of disposal. UVC light should never be exposed directly to skin or eyes; the light is encapsulated in the reactor during normal operation. In the case of alternative raw water sources, local requirements for approval and test frequency must be followed.

Tips for operating on rainwater
Choose sleeve sleeve in fineness adapted to roof and magazine type. Empty the bottom chamber regularly and use pre-separation before tanking. Dimensions flow conservatively during periods of high organic load in the raw water. Take annual microbiological samples and check sensors.
