- Up to 1.63 m³/h – 27 L/min for the treatment level indicated by the manufacturer as clean water
A suitable choice for a standard domestic installation with moderate flow requirements. For several bathrooms or higher simultaneous water demand, choose the 55 W UV pack.
This pack combines a self-cleaning filter, a triple 10-inch filter and a 25 W AMALGAM UV-C sterilizer. Each component works at a different stage to pre-filter the water, refine filtration through cartridges and finally provide microbiological treatment.
The 25 W version is particularly suited to a home with up to 4 to 5 people and one bathroom, with moderate simultaneous water demand. For several bathrooms or higher simultaneous water use, the 55 W UV pack provides a higher treatment capacity.
Particularly suited to a home with 1 bathroom and moderate simultaneous water use.
Each component has a specific role and is installed in the correct sequence.
Add only the extra cartridge your water actually requires.
Is the 25 W UV pack suitable for your home?
This 25 W version is particularly suited to homes where the number of water outlets used at the same time remains moderate, for example a family home with one bathroom.
The number of occupants is only a practical guide. The final choice should be based on the installation's instantaneous flow rate. For several bathrooms or higher simultaneous water demand, the 55 W version is more suitable.
Which water sources is this pack designed for?
This pack is intended for treating locally sourced water: rainwater stored in a tank, borehole water, well water or spring water.
Depending on its source, this water may contain sand, silt, rust, suspended particles, unpleasant tastes or odours, and may also present a microbiological risk.
The self-cleaning filter captures the largest impurities, the triple filter refines and customizes filtration, and the UV-C sterilizer acts on micro-organisms. UV treatment therefore does not replace the filters installed upstream.
How does the pack work?
The water passes through each piece of equipment in sequence so that every stage prepares the water for the next one.
1. Self-cleaning filter: protecting the installation
Installed as the first treatment stage, the self-cleaning filter captures larger solid impurities such as sand, rust and other deposits.
Its progressive filtration of 90 then 40 microns protects the finer cartridges installed downstream and helps prevent premature clogging.
The BACKWASH system performs reverse rinsing of the filter without having to interrupt the home's water supply.
The filter also includes a pressure reducer and pressure gauge and accepts 3/4" (20/27) and 1" (26/34) connections.
2. Triple filter: refining and customizing filtration
After pre-filtration, the water passes through a system with 3 standard 10-inch housings. This design allows several filtration media to be used in sequence while keeping the installation adaptable to the actual characteristics of your water.
Captures sand, silt, rust and other fine particles still present in the water.
Completes the filtration process and helps improve the taste and odour of the water.
The third housing remains free so that an additional cartridge can be installed if required, according to your water analysis.
The pack deliberately includes everything required to get started without adding several sets of replacement cartridges to the initial price. You can add extra consumables to your order according to your needs.
3. 25 W UV-C sterilizer: final microbiological treatment
The UV sterilizer is installed after the filtration stages. It uses UV-C radiation to act on micro-organisms present in the water and is not designed to retain particles.
As a simple guide, the 25 W model is particularly suited to a home with up to 4 to 5 people and one bathroom.
For several bathrooms or when several showers and water outlets may be used at the same time, choose the 55 W UV pack.
- Drinking-water treatment: 4.8 GPM – 18.2 L/min – 1.30 m³/h
- Treatment indicated as clean water: 6 GPM – 27 L/min – 1.63 m³/h
These values correspond to the stated specifications of the 25 W UV sterilizer. The actual instantaneous flow rate of your home should therefore be taken into account when choosing the model.
- UV-C lamp: 25 W AMALGAM
- Stated lamp life: approximately 16,000 hours
- Flow rate for drinking-water treatment: 1.30 m³/h – 18.2 L/min
- Maximum flow rate indicated for clean water: 1.63 m³/h – 27 L/min
- Chamber material: stainless steel
- Stainless-steel chamber length: 520 mm
- Outer diameter: 64 mm
- Connection: 3/4" – 20/27
- Maximum operating pressure: 6.8 bar
- Ballast cable length: 1.95 m
The 25 W AMALGAM UV-C lamp is rated for approximately 16,000 hours of operation, or up to around two years depending on operating conditions.
UV treatment acts on micro-organisms. It does not remove particles, correct turbidity or remove a specific chemical contaminant. Suitable filtration must therefore be installed upstream and, when borehole, well or spring water is intended for drinking, water analysis remains essential.
Why analyse borehole, well or spring water?
The composition of naturally sourced water can vary greatly from one location to another. Water analysis helps identify the characteristics of your water and determine whether the third housing should contain an additional treatment cartridge.
Depending on the analysis results, it can be fitted with an additional cartridge selected for the actual problem identified rather than adding an unnecessary treatment as standard.
What is included in the 25 W UV pack?
- 1 self-cleaning filter with pressure reducer and pressure gauge
- 1 triple filter with 3 standard 10-inch housings
- 1 x 5-micron sediment cartridge
- 1 x activated carbon block cartridge
- 1 free third housing for an additional cartridge
- Triple-filter connectors and accessories
- 1 x 25 W AMALGAM UV-C sterilizer
- Quartz sleeve
- 25 W UV-C lamp
- Ballast and power cable
- 2 mounting brackets
- Seals required for fitting the sterilizer
In what order should the pack be installed?
The order of the equipment is important: the different filtration stages must prepare the water before it passes through the UV chamber.
Water supply → self-cleaning filter → triple filter → 25 W UV sterilizer → home water system
Maintenance and consumables
The self-cleaning filter is cleaned by backwashing. Its operation can also be automated with the optional automatic backwash controller.
The triple filter uses standard 10-inch cartridges, making replacement easy and allowing a suitable additional cartridge to be selected for the third housing.
The UV-C lamp and some associated parts are consumables. The 25 W AMALGAM lamp is rated for approximately 16,000 hours of operation.
FAQ – 25 W UV filtration pack
Is the 25 W UV pack suitable for a home with 4 to 5 people?
Yes. It is a useful guide for a home with up to 4 to 5 people, one bathroom and moderate simultaneous water demand. The key technical factor remains the actual instantaneous flow rate.
When should I choose the 55 W UV pack?
The 55 W version is preferable when the home has several bathrooms or when several high-flow water outlets may be used at the same time. Its treatment capacity is higher than that of the 25 W model.
What flow rate can the 25 W model treat?
The sterilizer is rated at 4.8 GPM – 18.2 L/min – 1.30 m³/h for drinking-water treatment and up to 6 GPM – 27 L/min – 1.63 m³/h for the treatment level indicated as clean water.
Is this pack suitable for rainwater?
Yes. It combines pre-filtration, fine filtration and UV-C treatment and can be used for rainwater stored in a tank. The third housing allows an additional treatment cartridge to be fitted according to the intended use and water quality.
Is it suitable for borehole, well or spring water?
Yes. However, water analysis is particularly important when the water is intended for drinking so that any additional treatment requirements can be identified.
Why is the UV sterilizer installed after the filters?
Particles and turbidity should be reduced beforehand. The self-cleaning filter and cartridge filters therefore prepare the water before it passes through the UV sterilizer.
Do all three housings need a cartridge?
No. One sediment cartridge and one activated carbon cartridge are supplied. The third housing remains available for an additional treatment cartridge selected according to your water.
Why is only one set of cartridges supplied?
This keeps the starting price more attractive and allows you to choose how many replacement cartridges you want to order.
This pack combines three complementary stages for treating rainwater, borehole water, well water or spring water. The 25 W version is particularly suited to a home with up to 4 to 5 people and one bathroom, while the 55 W pack is designed for homes with more water outlets or higher simultaneous water demand.
