Ultra Violet Air Handler Bio Hazard Control

Anthrax is an acute infectious disease caused by the spore-forming bacterium Bacillus anthracis*. Anthrax most commonly occurs in wild and domestic lower vertebrates (cattle, sheep, goats, camels, antelopes, and other herbivores), but it can also occur in humans when they are exposed to infected animals or tissue from infected animals (CDC Website).

High output Ultra Violet (UV) Light Air Purification Systems is known to be effective in killing multiple types of viruses (please see below) and will reduce the risk of exposure. Irradiation takes place in the confined spaces of the Air Handler, thereby posing no threat to room occupants.

The B.C. UV Systems was specifically designed to operate in HVAC systems. The high output tube provides up to six times more energy than traditional UV lamps down to 32 degrees Fahrenheit. Fewer units are required, resulting in less total consumption.

The air flow velocity (fpm) of the air handling system is a major factor in determining the dwell time microorganisms spend within the HVAC cavity. It also affects the amount of heat removed from the UV lamps. The higher the air flow rate, the more UV light energy is required to achieve the desired destruction rate. The high power output of the BC UV System assures maximum killing power.

The typical standard for microbial control in IAQ application is to destroy 90% of E.coli on a single pass. By increasing the number of tubes and reflectors, destruction rates in excess of 99% can be achieved.

The UV tubes continue to function efficiently in cold temperatures with over twice the life of conventional UV lamps. Typical tube life is one year under continuos operation conditions.

Sizing:

Coil Size 91"Height x 126" Width
Air Handler Size: 91"Height x 126" Width

 

Coil Coverage of 24" Fixtures:

Number of Rows High = 4  
Number of Fixtures per Row = 5 System Total = 20 Fixtures
Fixture Width = 120" Inches Remaining = 3 on each side of the fixture
