UV Systems

Gentle on people and the environment

UV radiation is a safe, chemical-free and reliable method of disinfection in modern water treatment. ProMinent Dulcodes® UV systems exploit the safety and reliability of UV disinfection in a wide range of applications. Scientific research and the many systems successfully in operation prove that UV is ideally suited to water disinfection.

Our hero: UV-C radiation

No one wants germs - and UV-C radiation in particular, with a wavelength ranging from 240 to 280 nm, attacks the vital DNA of the bacteria directly. The bacteria lose their reproduction capability and are destroyed. Even parasites, like Cryptosporidia or Giardia, which are extremely resistant to chemical disinfectants, are efficiently reduced.

Not just for potable water

Photochemical reactions triggered by UV are used in other ProMinent applications too. The undesirable presence of combined chlorine in swimming pool water is reduced by UV radiation, achieving significant savings in fresh water. Oxidants, such as ozone, chlorine or chlorine dioxide, are reliably reduced in the production water used in the food and pharmaceutical industries, eliminating the need for expensive active carbon filters.

The advantages of UV treatment

Immediate and safe disinfection without the addition of chemicals. This results in highly effective disinfection regardless of the pH value. No undesirable substances are formed. The odour and taste of the water are not impaired. There is no need to store and handle chemicals. No reaction vessel or reaction tanks are required. A ProMinent UV system takes up very little space and keeps investment and operating costs low while delivering exceptional reliability and performance.

Products

UV System Dulcodes A

Flow up to 739 m3/h

The UV system Dulcodes A helps to ensure water quality. The UV system works energy-efficiently and cleanly based on continuously variable medium pressure lamps and can therefore automatically compensate for variations in the water quality or level of contamination. more

Your benefits

  • Simple installation, thanks to the compact inline system, ensures minimal installation work and fast retrofitting
  • Maximum flexibility when installing, thanks to the free choice of fitting position and direct installation in plastic pipes, as no UV radiation escapes from the reactor
  • External power control via 0/4 - 20 mA standard signal for optimum adaptation of the system to changing operating conditions, such as flow fluctuations
  • Automatic adjustment of the lamp output to a defined UV-C sensor signal with power increase to a raised, adjustable sensor signal via a digital input saves energy and extends the lamp service life.
  • Unbeatable simple and quick maintenance: All maintenance work can be carried out quickly and conveniently from one side.
  • Certified systems: NSF 50, CSA 22, UL508, comprehensively biodosimetrically validated to UVDGM 2006

UV System Dulcodes K

Flow up to 250 m3/h

Disinfection of saline sea water or thermal water without corrosion problems caused by the UV system Dulcodes K. The UV system consists of a reactor and a UV sensor made of highly UV-resistant plastic. more

Your benefits

  • Reactor made of UV-stabilised high-density HD-PE, absolutely corrosion-free and temperature stable.
  • Long-term salt water-resistant UVC sensor for monitoring the disinfection capacity, contamination of the lamp protection tubes, lamp ageing and water transmission.
  • Highly efficient Opti Flux 290 W lamps provide maximum disinfection and flow rate with a minimum number of lamps.
  • Ballasts with BUS interface for the gentle ignition and operation of the lamps
  • The replacement of lamps is reduced to the absolute minimum.
  • Low maintenance costs and low follow-on costs, as there are fewer, high-performance lamps featuring amalgam technology with an excellent service life of up to 14,000 hours.

UV System Dulcodes R

Flow up to 274 m3/h

UV system Dulcodes R for the disinfection of potable, process and swimming pool water. The system is used particularly when constituents, such as hardness, iron, manganese or organic substances, are present. Deposits are easily removed by the wiper mechanism even at maximum operating pressure without any need to interrupt operation. more

Your benefits

  • Cleaning without interrupting operation: the manual wiper is easy to operate even when the system is pressurised. Thanks to their self-sharpening function, the wiper elements deliver maximum cleaning and have a long service life.
  • Long-term stable UVC sensor for monitoring disinfection capacity, contamination of the lamp protection tubes, lamp ageing and water transmission
  • Greater performance with fewer lamps: energy-efficient high-performance Opti-Flux 300 W lamps permit greater flow per lamp
  • Longer maintenance cycles, reduced operating costs: 14,000 operating hours guaranteed (pro rata)
  • Electronic ballasts for gentle ignition and lamp operation: replacement lamps are kept to a minimum.

UV System Dulcodes S

Flow up to 569 m3/h

The UV system Dulcodes S for water treatment and disinfection in swimming pools. Combined chlorine is broken down and the typical swimming pool odour is eliminated: no more irritation for eyes, nose and skin. A manual stage switch permits adaptation to the required capacity requirement. more

Your benefits

  • Simple installation, thanks to the compact inline system, ensures minimum installation costs and fast retrofitting.
  • Maximum flexibility when installing, thanks to free choice of fitting position and direct installation in plastic pipes, as no UV radiation escapes from the reactor.
  • Automatic switching on and off based on the chloramine value, for example used in conjunction with the DULCOMARIN® II.
  • Unbeatable simple and quick maintenance: All maintenance work can be carried out quickly and conveniently from one side.
  • Manual power control for optimum adaptation of the system to the respective capacity requirement (not for Dulcodes 1 x 0.65 and 1S).
  • Manual or automatic wiper system for the efficient removal of deposits on the lamp protection tube. The wiper system can be easily retrofitted.

UV System Dulcodes W

Flow up to 600 m3/h
