New buildings are built tighter to save energy, while older buildings are implementing new measures to reduce heating and cooling loss. Reduced fresh air also prevents dilution of contaminated air resulting in an increase of contaminants as they are now trapped inside and are continually recirculated throughout the space.
Indoor Air Quality (IAQ) applications in hospitals, schools, commercial buildings and offices vary. From Hospital Acquired Infection (HAls), sick building syndrome, absenteeism and work place productivity, Indoor Air Quality influences these facilities in many differents ways.
When the objective is to eliminate up to 99.9999% of airborne bio-contaminants, including viruses and bacteria that circulate through the ventilation system without increasing the pressure drop resulting from high efficiency filtration, Sanuvox offers the right solution with its high efficiency patented air purification system.
The BioWall air purification unit is installed in the ventilation duct parallel to the airflow, allowing sufficient contact time that is required for airborne sterilization. The UV-C intensity of each lamp can be measured in “realtime” with an optional UV-C sensor, ensuring the required inactivation intensity will be delivered to the contaminant.
OPERATING THE EQUIPMENT
To create the sterilization chamber in the existing duct (up to 5 feet deep per unit), the walls are covered with an aluminum reflective material. The proprietary sterilization sizing calculations take into account: air velocity, dimensions of the duct, the UV lethal dose needed to sterilize the microorganism for the desired inactivation rate. The sizing calculations will determine the number and length of the BioWall unit(s) required. The optional UV-C sensor will guarantee that the UV-C emitted from the lamp will exceed the amount of UV-C that is required at all times.
UVC GERMICIDAL PRINCIPLE
The 254nm UV-C germicidal wavelength has been used for decades for sterilization and its effect on microorganisms is well documented. UV germicidal process inactivates microorganisms by damaging their DNA structure, making it incapable of reproducing. The germicidal efficiency can deliver virtually a 100% disinfection rate. The system can achieve exceptionally high disinfection rates as a result of the BioWall unit being mounted parallel to the airflow and the desired intensity is sized for each particular application.
WHERE TO INSTALL
Many buildings and facilities can be equipped with the BioWall unit, like hospitals, private clinics, veterinary clinics, as well as fertility centers. It can also be installed in schools, universities, offices towers and commercial buildings.
