Why combine AHU and ventilation?
The advantage of combining an air handling unit (AHU) with ventilation —as is the case in a dual-flow air handling unit —is that stale air is replaced with fresh or recirculated air, all using a single unit. The drawback of conventional systems is the risk of microbial contamination via the heat exchanger. To address this, check out the PhotoClean universal modules!
Air Pollution: A Real Problem in the Workplace
Regardless of your industry (medical, food industry, service sector, or other), the presence of contaminants in the air poses a variety of problems:
- risks to human health
- economic consequences
- failure to comply with legal obligations
Indoor air, especially in enclosed spaces, is contaminated by countless pollutants, such as bacteria, mold, viruses, microparticles, VOCs, and more. Fortunately, there are effective solutions available to restore healthy indoor air quality that fit your budget.
Dual-flow AHU: The System’s Limitations
Dual-flow air handling units are interesting because they combine air treatment with air renewal, and their operating principle is fairly simple. They draw in stale air, treat it, and then partially replace it with fresh or recirculated air before returning it to the duct system. It is during the recirculation process that the risk of contamination arises. Indeed, if viruses—such as the COVID-19 virus—are present in the air, they can reach the heat recovery unit and remain there. The unit then carries these unwanted particles into the air returned to the system!
Air Disinfection in Air Handling Units
To help you enjoy air free of viruses and pollutants without having to invest in equipment that is both costly and energy-intensive, PhotoClean is proud to present a unique technology for air decontamination in air handling units: photolysis.
Developed exclusively by Photoclean, this process combines the natural sterilizing power of UV-C rays with the semiconductor properties of silica fibers. The benefits are numerous:
- no accumulation of pollutant particles
- systematic and continuous destruction of microorganisms and chemical molecules
- efficiency approaching absolute filtration, with incomparably lower energy consumption
- Optimized installation, setup, and maintenance costs
- Compatibility of our modules with all dual-flow air handling units and treatment systems
Protect Your Premises from Microbial Contamination
By treating the air directly within the air handling units (AHUs), our modules enable these units to return perfectly decontaminated air to your facilities. Your system thus ensures optimal treatment and renewal of the ambient air, even in confined spaces or environments with high levels of pollutants.
Our solutions are ideal, particularly in healthcare facilities, but also for ensuring healthy working and production conditions in food industry plants, dairies and cheese factories, manufacturing plants, and more.
Manufactured exclusively in our facilities near Lyon, our products are available in various lines to meet your needs: customized airflow, temperature and humidity control, pressurization or depressurization of spaces, and more.
We also offer mobile air-handling units. Contact us today and schedule an audit of your facilities!
