98% Of Particles Are Too Small To Be Influenced By Airflow
The particles in a room vary in size, concentration and settling time. What happens to these particles depends almost solely on their size and to some degree, their age. Well-established facts of physics has demonstrated that there are two primary forces at work that affect particle movement. One is air movement created by the HVAC system and the second is the naturally occurring electrical fields that exist in all rooms. 98% percent of the particles, in typical indoor air, are 3 microns or smaller in size and due to their small cross sectional area cannot be moved by air currents. Particles of this size are controlled, to a much larger degree, by the naturally occurring electrical fields (this is why small particles tend to “plate out” or cling to electronic devices such as TVs and computer monitors). These contaminants stay behind and create, not only a serious health hazard for occupants, but also a costly maintenance issue for owners.
Particle / Contaminant Behavior
As particles age they naturally collide with one another and as a result, stick together creating a larger particle. This naturally occurring phenomenon is called “coagulation”, and as one prominent researcher stated, “is the most important phenomenon in the interactions of aerosols (airborne particles).” As particles coagulate, through this random process of collisions, the end result is a reduction in the volume of submicron particles and an increase in the larger particles (both size and volume). As particles increase in size the cross-sectional area eventually becomes large enough for normal air currents to now move them. This naturally occurring process is exceptionally slow and thus has virtually no effect on eliminating contaminants from an occupied space.
Excitation – How It Works
Excitation discovered long ago that the natural process of coagulation could be greatly influenced by the use of a “non-homogenous in-duct electrical field”. A non-homogenous electrical field is comprised of two grids mounted 3″ apart from one another. One grid is a high voltage (HV) field and the other is a high frequency (HF) field. These two fields have a dramatic effect on particles coming in close proximity by greatly increasing the speed and direction of the particles. The rate of particle collisions is increased exponentially resulting in a rapid decrease in small particles (submicron) and a rapid increase in particle size.
As particles increase in size they can then be picked up by the HVAC system and moved through ducts and trapped by the filters to be removed. The particles are “carbaceous” (containing or composed of carbon) so VOC’s, gases and other odorants tent to absorb and adsorb onto them turning them, in effect, into “micro-miniature carbon beds.” The coagulated particles work somewhat like snowballs rolling downhill sweeping up fine particles increasing the proportion of large contaminants carried and trapped by the filters. The Excitation Technology is the only air purification technology that uses unique, patented solid-state mechanisms to increase particle size allowing particles to be moved by the HVAC system to the filter and removed permanently.
Excitation – Summary
Standard mechanical systems are designed to remove particles that can become air entrained; 3 microns in size. 98% of all particles are submicron in size and therefore are less influenced by the controlled airstream. Excitation accelerates the natural process of conglomeration, a process by which particles collide, stick together and grow in size. As the particles reach 3 microns in size, they become air entrained and return to the mechanical filters for removal.
Excitation allows the particles that would naturally remain in a space to be removed; effectively cleaning the air.
Real time monitoring keeps buildings cleaner and safer
The CosaTron Advantage
Breathe easy
and spend less
CosaTron is the most effective way to minimize contaminants in a building. It does this by controlling and eliminating dangerous airborne particles, which leads to safer buildings—and reduced energy costs.
Control, remove
and reduce particles
We use a patented high-tech system to clean indoor air. Our technology increases the size of airborne particulates in a given space, allowing them to be transported and filtered out by your HVAC system.
CosaTron equipment produces zero CO2 and zero ozone
CosaTron is the only technology that produces no negative side effects while controlling the particulates generated from chemical, biological contaminants and poor ventilation.
The CosaTron
Effect
CosaTron technology increases particle size—which, in turn, helps those particles absorb more VOCs, gases and odors. These larger particles are then easier to remove with standard HVAC filters.
