HORECA: Case Study Euroveacity - Bratislava (Slovakia)

We are proudly part of the Eurovea City of Future project in Bratislava!

Eurovea will become the ideal place for living and relaxing in the center of Bratislava. The central feature will be Slovakia’s first skyscraper - Eurovea Tower.
Aside 285 000 m2 of office spaces, 95 000 m2 of retail spaces and 1 470 Apartments, the property also features 120 cafes, bars and restaurants.

Currently, 6 restaurants have been equipped with Light Progress UV-SMELL-SQ devices for Odor&Grease reduction inside kitchen hoods and kitchen extraction ducts.

To guarantee a great customer experience in modern and refined shopping malls, every restaurant shall keep kitchen odors under control. And prevention of flammable grease sediments inside kitchen hoods and ducts is also essential to guarantee a safe environment for visitors and employees.

The project includes restaurants from different culinary traditions, including an Indian fast-food restaurant, a German restaurant, a German restaurant with fish specialties, a Vietnamese restaurant, an Italian restaurant and a Mexican and Asian restaurant.

For the Italian restaurant, Ozone lamps have been the preferred choice due to the high performance of the Ozone for smell reduction inside kitchen extraction ducts.

The average extraction capacity of each restaurant is 4.000 m3/h for a complete installation of 31.600 m3/h.

A filtration plenum has been designed, built, and installed for the application's design for every duct. The average size of each plenum is mm. 1340x400x400.


Ultraviolet rays are electromagnetic waves which are part of light. Electromagnetic waves are divided into three main wavelength bands, expressed in nanometers, nm: Ultraviolet rays (UV) 100-400 nm Visible rays (light) 400-700 nm Infrared rays (IR) 700-800,000 nm UV rays are in turn identified in three bands:

  • UV-A (315-400 nm) with tanning properties;
  • UV-B (280-315 nm) con proprietà terapeutiche e di sintesi della vitamina "D";
  • UV-C (100-280 nm) with germicidal properties.

UV-C rays (100-280 nm) have a strong germicidal effect and reach their maximum efficacy at the 265 nm wavelength. The germicidal effect of UV-C radiation covers bacteria, viruses, spores, fungi, moulds and mites; this is mainly due to the destructive effect of the UV-C rays on their DNA, which damage their reproductive system and prevent them from replicating.

Bacteria, Viruses, Spores, Fungi, Mould, and Mites are all sensitive to, and can therefore be eliminated with, UV-C light. Mircrobes cannot acquire resistance to UV-C light, unlike that which occurs using chemical disinfectants and antibiotics. UV rays are ecological. Polluting the environment is inevitable using normal disinfectants. Directly inhaling the vapours, or swallowing food products contaminated by any contact with said chemical disinfectants, can also give rise to a number of serious risks. In cases where chemical disinfectants cannot be eliminated (food, pharmaceutical, healthcare industries, etc.), using ultraviolet rays for disinfection allows a reduction in their use, with considerable economic savings and greater care for the environment, while maintaining and almost always improving the level of disinfection. UV-C light devices can be installed in environments and on machinery and be programmed to maintain the same level of disinfection day and night, guaranteeing ideal hygiene conditions, without highs and lows. On the contrary, chemical disinfectants are effective only during their actual use. Using LIGHT PROGRESS equipped luminaires, operating costs are negligible; it could be said that “LIGHT PROGRESS” UV-C systems do not require maintenance except for the normal replacement of the lamps. The cost/benefit ratio is considered excellent; the devices are both powerful and long-lasting. Hence the elimination of germs using UV-C technology is low-cost and highly effective compared to (or in combination with) other systems.

UV-C really does work when applied correctly and with the necessary precautions. The difference between a quality project and an unsuccessful application is in-depth knowledge and experience gained over time. Since 1987, Light Progress has been carrying out successful projects all over the world and has acquired a clientele of major companies in all sectors that require verified hygienic conditions to produce quality products and services.
