CosaTron is a unique and patented system that does not generate ozone, ionization, or high frequency interference.

CosaTron is not an air filter. It is applied in combination with an air filter to enhance the performance of the filter.

The CosaTron System includes an electrode assembly located in the primary air handling unit, after the filters, before the heat transfer coils, on the suction side of the fan. The electrode assembly is made up of two elements, high voltage (HV) and high frequency (HF), separated by special insulators. The electrodes are powered by a patented generator connected to an ordinary 120 V, 60 Hz outlet, requiring the energy of a 50 watt light bulb. (Note: other power supply generators are available to meet each country’s standards).

The ‘Physics’ of CosaTron®ⁱ

There is a natural electrical field between the Earth and the upper atmosphere. At ground level, the electrical field intensity is, on average, about a hundred volts per meter. This natural electrical field is everywhere, including inside of buildings.

This natural electrical field inside buildings is rather complex; it is distorted by the electrical wiring in the walls, electrical equipment, metal ducts, etc. The electrical field inside of a room can be visualized as a distorted cobweb of electrical lines of force.

In all rooms, there are a large number of particles in the air. Most of the particles come in from outside. These particles normally carry an electrical charge. These charges are due to cosmic rays, the slight radioactivity in building materials, frictional charging of materials, operating electrical equipment, etc.

The particles in a room vary in size. What happens to these particles in a room depends on their size. The larger ones are controlled by gravity, they tend to drift down and fall onto the floor. These are vacuumed up during normal housekeeping. The medium size particles are controlled by the air currents in a room that are created by the HVAC system. They are entrained by the air currents and carried to the returns, thence to the filters and they are caught in the filters.

The fine particles, which are 98 percent of the total particles by count, are controlled by the normal electrical fields in a room and relatively few of them are entrained by the air currents. The fine particles, less than about 2 microns in size, are so light and have such small cross sectional area that the air currents do not see them, so to speak.

From a physics standpoint, the fine particles are constantly moving along a room's electrical lines of force. They collide with other particles and tend to stick together. In physics, this is called coagulation. In this way, they ultimately form medium size particles. When they get to that size, they can be entrained by the air currents and carried to the filters. Details of the physics are available; they are spelled out in several published papers in scientific and engineering journals.

CosaTron® In Operation

CosaTron® is a patented high tech means to accelerate this natural process of coagulation, thereby minimizing contaminates in the air. There are number of papers published in scientific and engineering journals that report research that shows the effectiveness of CosaTron®. CosaTron's action occurs in the vicinity of its electrodes in the duct and continues in the room.

Specifically, air in a duct passes first through a filter which removes the medium size particles entrained by the air currents. Most of the fine particles in the air pass through the filter. This air then goes into the section of the duct which contains the CosaTron® high voltage high frequency fields which are created in the vicinity of the CosaTron® electrodes. In the CosaTron® HVHF field, the fine particles are accelerated and are driven in a lengthy chaotic path. This increases the probability of collision and greatly increases the rate of coagulation. These coagulated particles then go into the room via the supply diffusers. In the room air, they act like snowballs rolling down a hillside; they pick up many more fine particles. These, now medium size, particles can be entrained by the air currents, carried to the returns and are caught by the filters. Thus, since the natural process of coagulation is greatly enhanced by CosaTron®, the air in the room is kept much cleaner than it normally would be.

This action in the vicinity of the CosaTron® electrodes in the duct can actually be seen. It has been filmed in an actual duct using smoke particles so that the CosaTron® action is visible.ii

Research reported in additional scientific and engineering journals shows that CosaTron® is also effective in minimizing other contaminants such as VOCs, bacteria, viruses and odorants. The reason that CosaTron® is so effective against these other contaminants is that fine particles are typically carbonaceous. They absorb and adsorb these other contaminants somewhat like charcoal would. Thus, when the coagulated particles are entrained by the air currents and carried to the filters, these other contaminants are carried with them and are also removed.

CosaTron® is a patented high tech means to accelerate a well understood phenomenon in physics, i.e. coagulation of particulates. CosaTron® is a very effective means to minimize contaminants in a building and to save on energy costs; facts documented by research in the laboratory as well as in actual buildings and published in a number of scientific and engineering journals.
