SpAOP is a compact system using direct UV-C generation technology (eliminating the need to generate ozone). The unit is ideal for water treatment in hot tubs and other SPA equipment.
Spaop 21 W Z20 is a special version of the UV-C lamp designed for hot tubs and spa systems. It differs from the standard Spaop 21 W mainly in the type of connection and system compatibility. While the basic Spaop 21W has a universal or standard connection, the Z20 version uses a 20 mm diameter connection, which allows for easy and secure installation in systems that require this size. This difference is crucial when replacing the lamp, because although both lamps have the same 21 W output, the same UV-C disinfection efficiency and a similar service life of around 9,000 hours, the Z20 version is a perfect fit for equipment where a 20 mm hose connection is required, ensuring proper seating and a tight seal. In addition to the connection, the Z20 design is adapted for easier installation and maintenance.
Ultraviolet disinfection is one of the technologies increasingly used in recent years to improve the treatment of drinking and pool water. The principle of disinfection lies in the photochemical damage of RNA and DNA, proteins, enzymes, and other biologically important macromolecules. The effectiveness of disinfection depends on the UV dose, the type of UV lamp used, and their arrangement in relation to the flow direction of the drinking or pool water. To select the appropriate type of UV unit correctly, it is necessary to determine and ensure the required UV dose, which depends on the flow rate and the water quality in terms of its transparency, i.e. the concentration and type of dissolved and undissolved substances that affect the reflection or absorption of UV radiation.
The possibility of combining UV radiation with other treatment technologies leads to achieving high water quality. The advantage is reduced operating demands, i.e. savings in dosed chemicals and safe, simple operation in automatic mode.

Why choose Spaop?
Choosing the Spaop 21 W UV-C sterilizer is the ideal solution for anyone looking for a reliable and eco-friendly way to treat water in a hot tub or small pool. Unlike traditional disinfection methods, this system uses ultraviolet radiation to eliminate bacteria, viruses, and algae, while leaving no chemical residues in the water. As a result, the water is not only crystal clear, but also gentler on the skin, eyes, and respiratory tract. Spaop is specially designed for use at higher temperatures, up to 40 °C, making it ideal for hot tubs. Its compact design allows for easy installation even in limited spaces, and maintenance is minimal. At the same time, it significantly helps reduce the consumption of chemical products, which is beneficial not only for users’ health but also from an economic and environmental standpoint. The sterilizer is made of high-quality materials resistant to corrosion and high temperatures, ensuring a long service life. Spaop 21 W is a product of the renowned Dutch manufacturer Blue Lagoon, known for its high manufacturing standards and precise UV-C disinfection technology.
