The UV system Dulcodes LP-F&B, developed especially for applications in the food and beverage industry, disinfects product water efficiently and without using any chemicals. ProMinent is presenting the new system on booth 6-208 in hall 6 at BrauBeviale 2018 between 13 and 15 November 2018 in Nuremberg.

Chemical-free disinfection in line with hygienic design requirements

What is special about the new UV system Dulcodes LP F&B is that its patented Vario-Flux high-output lamps with dynamic lamp heating enable fast, precise control. They ensure automatic adaptation to varying flows at all times, regardless of the water temperature.

As an added benefit, they are characterised by their high UV output and minimal ageing behaviour.

Thanks to the unique combination of electronic ballast technology and Vario-Flux lamps, they can be controlled quickly and precisely over a broad range of up to 50 % of the nominal power. Efficiency increases in dimmed mode. This has a particularly positive effect when the actual flow is below the maximum possible flow of the system. Seasonal fluctuations in water temperature no longer play a role and are simply compensated for.

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

The stainless steel housing with no welded seams on the inner reactor shell satisfies hygienic design requirements. Free of gaps and dead space and featuring smooth surfaces (roughness < 0.8 µm), this design ensures quick and easy cleaning (CIP Cleaning In Place). Bacterial colonies and cross-contamination are reliably prevented. The pipes are connected using Tri-Clamp connectors.
