Crystall Sabiana
The current pandemic and resulting health crisis that is putting humanity and the global economic and production system in great difficulty, has increased awareness about the quality of the air we breathe, especially in indoor residential environments and in the workplaces, to which we all hope to be able to return in the coming months.
This invisible enemy, much more dangerous and difficult to fight, spreads in the air we breathe and when it infects us it attacks the entire respiratory system.
The social distancing measures adopted on a national but also on an international level, which involve our staying in our homes for a long time, makes us increasingly reflect on how important it is to be concerned about and deal with the quality of the air we breathe in our homes, where we will be spending much more time, also due to the new ways of working remotely or restrictions on mobility.
Since viruses and bacteria spread in the indoor air of confined spaces, which we all breathe for many hours a day, its quality is, and will necessarily be, entrusted to Ventilation systems equipped with adequate Filtration. This will increase the attention of public institutions, individuals and all operators in the industry and will become the engine that will drive new engineering solutions in the coming months and years.
Every day we read and hear from the various media of new scientific research that links the increase in the spread of infections and the fatality rate of the Covid-19 virus to fine dust (PM10, PM2.5 and PM1), which the WHO has always considered as the main cause of diseases affecting the respiratory system and which claim tens of thousands of victims per year.
For over 25 years Sabiana has promoted the concepts of indoor Air Quality and the importance of designing air conditioning and ventilation systems in a rational manner and aimed, also and above all, at protecting human health. With its courses it has trained and raised the awareness of thousands of professionals in Italy and will continue in this campaign, which, now more than ever, is of extreme social utility.
The Sabiana Crystall electronic filters (or active electrostatic plate filters), patented and available on all hydronic terminals, are the concrete and easy-to-implement response to the risk associated with the spread of both chemical and microbial pathogens in the environment.
The solutions equipped with the Crystall electronic filter have 3 fundamental effects on reducing the risk associated with the spread of pathogens in the environment:
1 they retain fine particles, with an efficiency of up to 95% for PM1 (new Crystall 150 filters); since fine (liquid and solid) particles are the main carrier that conveys all the substances present in the air into our lungs, reducing dust in the environment is a first step towards the reduction of the risk associated with the spread of pathogens;
2 electronic filters have an effective biocidal action on transiting air, certified by the University of Ancona: such action is effective on various microbial pathogens, both due to the action of the high voltage electrostatic field and to the slight production of ozone around the plates;
3 electronic filters have a high biocidal action on what is deposited on the filter: the filter is therefore no longer a passive element that amplifies biological contamination (like traditional mechanical filters), but an element of the ventilation system that reduces it.
In short, as well as retaining part of the substances suspended in the air, the minimal percentage that is not filtered is partially passivated and what is deposited on the filter is almost entirely passivated.
For this reason, we can say that they are more than filters: they are actual air purifiers.
The removal action is as effective on fresh air and recirculation air on an AHU as it is crucial on a fan coil (secondary air), which handles at least 5/6 volumes of ambient air in an hour and therefore purifies the ambient air repeatedly (it purifies all the ambient air every 10/12 min).
Sabiana Crystall filters are certified according to Standard UNI EN 16980 and feature several other advantages in terms of reducing ventilation consumption on an AHU, reducing the contamination of the duct connections, reducing maintenance costs, etc. For further information, please refer to our documentation.
Crystall electronic filters can be applied to the following SABIANA products:
• Fan coils with casing,
• Cassette fan coils,
• Recessed fan coils,
• Controlled Mechanical Ventilation (CMV) units
• Air Handling Units, also applied to already installed AHUs made by other manufacturers
• Systems for duct or outlet installation
Finally, we wish to point out that the correct design of air diffusion systems, which promote good ventilation efficiency with several supply points at the top and several return points at the bottom to prevent pathogens from “wandering” throughout the environment, is a mandatory practice to be followed more than ever at this historical time.
We have always been a benchmark in the Ventilation and Air Quality industry.
Please contact our agents and sales representatives for all the necessary details.
We put our expertise, developed over the years, at your disposal to counteract, today and in the future, the massive spread of substances harmful to humans in confined spaces.
Sabiana will also hold a Webinar on the topic shortly: you will be notified of the date (or dates) in order to take part and further explore these topics.
