Great food smells amazing—but not on your clothes. 
If lingering odors and VOCs create discomfort for customers and staff, UV-FAN provides a powerful solution. It purifies the air, reducing unwanted smells and improving comfort for everyone.

CHALLENGES


La Cocinona is a vibrant kitchen in the heart of Madrid, dedicated to preparing high-quality takeaway food. Its central location makes it easily accessible, but also presents challenges in managing airflow within a compact space. During cooking hours, heat and aromas build up inside the premises, leading to the frequent need for ventilation by opening the doors. This creates a dynamic air exchange between the kitchen and the street, influencing indoor comfort for both staff and visitors.

What is in  the air?
(VOCs) like formaldheide are released during cooking, along with smoke, grease particles, and humidity. Heat and air circulation spread these compounds, making odors linger on surfaces, fabrics, and in the air.Proper ventilation and air purification help manage these airborne elements, ensuring a fresher environment.

PROPOSED SOLUTION
To maintain a pleasant atmosphere, La Cocinona has implemented various ventilation solutions, including ozone generators. However, balancing effective airflow while ensuring an optimal indoor environment remains a key focus. Opening the doors for ventilation can lead to air circulation challenges, affecting both the workspace and the surrounding area. Following a thorough analysis of La Cocinona’s layout, ventilation system, air circulation, and particle levels, the installation of 4 UV-FAN units was recommended to enhance air quality and reduce odors.
These units are strategically placed based on key factors such as odor sources, airflow patterns, and room volume:

1 - Entrance corridor – to address air movement at the main access point
2 - Storage/Fryer area – where cooking emissions are most concentrated
3 - End of the entrance corridor– to reinforce air purification along the airflow
4 - Rotisserie section –another significant source of airborne particles

Each UV-FAN unit is equipped with an hour counter, allowing for precise tracking of operating hours and timely lamp replacements, ensuring consistent performance. Additionally, the air conditioning system has been reviewed and found to be adequate, confirming that the proposed solution integrates effectively with existing ventilation.
In addition to the UV-C lamps, UV-FAN also contains an innovative titanium dioxide nano-particle filter, TiOx®, which enhances the germicidal action with additional odor control.

  
Let your clients enjoy their meal in a fresher atmosphere, work more efficiently, spend less time on cleaning, and provide a wonderful experience for all.
 
THE TEST
During the pilot test, when the entrance door remained closed for 11 minutes (from 11:17 to 11:28), a significant reduction in airborne particles was observed due to the operation of the air purifier:
- Particle count reduction: From 175 to 60, a 65.7% decrease
- Particle mass reduction: From 21.7 to 7 units, a 67.7% 


These results confirm the air purifier's effectiveness in rapidly improving air quality by significantly reducing airborne particulates in just 11 minutes.
           
These results were measured using a instrument for IAQ, confirming the purifier’s ability to significantly reduce airborne particulates and rapidly enhance air quality.

BENEFITS
1- Cleaner Surfaces
Less frequent wall cleaning and reduced floor slipperiness by lowering airborne grease buildup.
2- Fresher Work Environment
Minimized odors on work clothes and improved air quality, reducing irritation and discomfort..
3- Better Airflow Management
Fewer ventilation needs while maintaining a fresh indoor environment.
4- Effective Odor Control
Reduced odors inside and on Bolivar Street for a cleaner, more pleasant atmosphere.
5- Seamless Integration 
Easy to retrofit with no need for disruptive installation, ensuring quick and hassle-free implementation..

F.A.Q.

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.
