Ultraaqua A/S

- Model SS - UV Systems for General Water Disinfection


ULTRAAQUA’s SS closed reactor series are built from high-grade AISI 316L steel are suitable for most water  disinfection applications. UV sensor and automatic mechanical cleaning systems are available. The three standard series 220 SS, 350 SS and 440 SS and the ÖNORM SSV Validated Series cover a large variety of flows and doses.

  • Corrosion-resistant electropolished stainless steel AISI 316L construction
  • Simple installation, operation and maintenance
  • Improved energy efficiency for clear water due to internal reflection of UV light
  • Operating pressure up to 10 bar
  • No tools needed for regular maintenance
  • Available with standard or advanced controls


Third party validated UV system

One entirely product series has been validated according to ÖNORM M 5873-1 – UV ÖNORM Validated systems for drinking water applications, based on ULTRAAQUA’s newly patented SwirlFlow™ technology.

Please note that 220, 350 and 440 series are based on the same design principles and quality components. Key components such as UV lamps, quartz sleeves, lamp drivers, sensors etc. are manufactured according to the exact same very high technical standards.

UVT – UV transmittance

UVT describes how well UV light penetrates the water. In relation to UV system sizing this parameter is as decisive as water flow rate. In general, the higher the water quality, the higher UVT. However, water that looks very clear can still have low UVT if it contains certain dissolved substances such as iron, manganese, etc. ULTRAAQUA offers free in-house measurement of UVT from a supplied water sample.  

For low UVT applications (UVT < 70%), please consider LUVT Series.

InLine (440 series) or U-configuration (75, 220 and 350 series)

In many cases it is an advantage that inlet and outlet are on the same level. This is often the preferred configuration for installations to fit existing pipe systems. If the UV system is installed with a bypass, the U-configuration is often the simpler solution.

Custom-made systems

ULTRAAQUA can offer optimized custom-made UV systems based on your specific requirements. ULTRAAQUA can offer UV systems with customized connection sizes and/or orientation. ULTRAAQUA can also offer even larger systems than the standard current available.
