Air handling and purification in centralised systems

Appropriate technologies for healthy and clean air

Today more than ever, our well-being and health depends on the ambient conditions of the buildings and venues in which we spend most of our time.

Centralised air handling systems must include a purification step, whereas in cases where there is no mechanical ventilation, locally applied air purification systems are integrated with ventilation to obtain clean, pure air inside the building.

CENTRALISED AIR CONDITIONING SYSTEMS

Integrations into main ventilation


The quality of building ventilation directly affects the relationship between the airborne transmission of respiratory infections and people’s health and productivity. The recent pandemic has sparked increased interest in the implementation of UV-C technology for the disinfection of airflows and improvement of the indoor air quality.

Various government organisations and supranational entities suggest the use of UV-C light as a recommended mitigation step to reduce the airborne transmission of diseases and improve the indoor air quality in all types of buildings. Like most tools, UV-C systems, if used properly and implemented in accordance with proper testing criteria, can do much to improve the indoor air quality and health of the building’s occupants, guaranteeing excellent performance and safety.

How it works

UV rays eliminate up to 99.999% of microorganisms such as viruses and bacteria, destroying their DNA or RNA with minimal effort and without the use of hazardous chemicals or gases. The UV rays do not leave any residue, so the environments are immediately ready for use without any risk

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 light genuinely works if properly applied and with the necessary precautions. The difference between a quality project, and an application that fails to bring the desired results, lies in the degree of knowledge about the subject, and level of experience acquired over time. Light Progress has been developing successful projects worldwide since 1987, and has built a client portfolio consisting of important companies in all fields requiring certified hygienic conditions to produce quality products and services.
