A world first: precise lamp dimming in seconds – even with varying flows and water temperatures.

Flow up to 523 m³/h

The unique UV systems Dulcodes LP are synonymous with pioneering water treatment – efficient and free of chemicals.

Our patented Vario-Flux high-output lamps with dynamic lamp heating are used in the Dulcodes LP. Thanks to the unique combination of electronic ballast technology and the Vario-Flux lamps, they can be quickly and precisely dimmed over a broad power range of up to 50% of the nominal electrical power. This ensures automatic adjustment to varying flows and water temperatures at all times.

Efficiency even increases in dimmed mode, which has a particularly positive effect when the actual flow is below the maximum possible flow of the system.

The flow in the Dulcodes LP has been optimised in a reactor based on intensive computer simulation. At the same time the pressure loss is kept minimal. The resulting uniform radiation dose without over- or under-metering of a partial volumetric flow leads to minimal use of energy, a minimum number of lamps and significantly reduced life cycle costs.

Your benefits

  • UV system Dulcodes LP for a broad field of application for efficient, safe and chemical-free water disinfection
  • Unique dynamic lamp heating adjusts the lamp output in seconds and provides for optimum disinfection even with rapidly varying flows and water temperatures
  • Homogeneous UV dose, thanks to optimised flow characteristics in the reactor, guarantees maximum flow output with a minimum number of lamps and minimum pressure loss
  • Reduced life cycle costs due to the long service life of Vario-Flux high-output lamps with low energy consumption and high UV output
  • High flexibility thanks to vertical or horizontal installation and free choice of the flange position
  • User-friendly and intuitive control for the display of operating statuses and adjustment of operating parameters

Field of application

  • Potable water treatment
  • Food and beverage production
  • Swimming pool water

Technical Details

  • CFD (Computational Fluid Dynamics) optimised reactor made of high-grade stainless steel 1.4404/AISI316L by means of computer simulation
  • High-output amalgam lamp "Vario-Flux" with dynamic lamp heating
  • Guaranteed lamp service life of 14,000 operating hours (pro rata)
  • Electronic ballasts for the gentle ignition, operation and individual monitoring and control of the lamps
  • Long-term stable UVC sensor for continuous monitoring of the system
  • Efficient and chemical-free cleaning of the cover tubes with manual or automatic wiper system, optionally available for selected system sizes
