The UV Bio-Wall

The UV Bio-Wall are individual UV Arrays which work together in providing a “barrier wall” of Germicidal UV
Energy which will destroy virtually any biological contaminant which would pass through it.
Each Bio-Wall has 5 High Intensity 19mm. Quartz Lamps, which are mounted to Parabolic Reflectors that
reflect a full 360° of Germicidal Radiation.

The Two Inch UV Rule

For those who are not familiar with this term, here is a quick summary.

According to the Lamp Manufacturers, efficiencies DROP very

quickly the further from the UV Lamp surface you move.

At just 2” from the surface of the glass, the UV efficiency has

already dropped 80% and the decline is not exponential.

This is true for all types of UV Lamps, from cold cathode to hot

cathode, soft glass to quartz glass.

The Two Inch Rule is extremely important, it is the principal that governs UV

Air Purification.The Two Inch Rule is ONLY applicable for air purification (treating moving air).

Sanuvox In-Duct Purifiers

Sanuvox In-Duct UV Air Purifiers (R1500X, R3500X and C2000X)
are extremely efficient .
The In-Duct Purifiers are relatively small in size (the C2000X,
Sanuvox’s largest Commercial In-Duct UV Air Purifier measures 20” x 9”).
Sanuvox In-Duct UV Purifiers do not purify the entire volume of air in the
duct at one time. The air passing thru the Aluminum reflector Tube will
be treated, the purifier relies on the re-circulation to bring the overall level
of contaminants down.
The reason why Sanuvox In-Duct Purifiers are so effective in destroying
airborne contaminants is because the purifiers can:
a) Slow and Spin the air close to the UV lamp increasing the Dwell time in
order for the contaminant to receive a higher dosage of Germicidal UV (Turbulator).
b) Intensify the UV Energy thru the use of Reflection. The more powerful the UV Energy, the higher the UV
dosage delivered to the contaminant (Aluminum Reflector Tube).
C) Positioning the Purifier Parallel to the air stream increasing the Dwell Time. In contrast, if the purifier was
positioned perpendicular to the air, the contaminant would “zip” right by the lamp not spending very much time
in contact with the UV Energy.

Size DOES Matter

How does the UV Bio-Wall treat ALL the air in the duct at one time?

Because the UV Bio-Wall is designed to treat all the air in the duct, Sanuvox can not slow ALL the air down

as it travels over the lamp.

To compensate for NOT slowing the air down, the Bio-Wall MUST deliver an extremely high amount of UV

over a much greater distance.

How does the Bio-Wall deliver the UV dosage

needed to kill contaminants in the moving air?

The UV Bio-Wall

High Intensity 19mm. Quartz UV Lamps / Parabolic Reflectors

Each Bio-Wall has 5 High Intensity 19mm. Quartz Lamps, which are mounted to Parabolic Reflectors that reflect a full 360° of Germicidal Radiation.

The UV Bio-Wall Lamps can be upwards of 60” long

The UV Bio-Wall

High Intensity 19mm. Quartz UV Lamps / Parabolic Reflectors

Sanuvox Lamps are Quartz glass not Soft glass. Quartz glass produces higher levels of UV Intensity and have a longer operating life than Soft Glass.

The Lamps are special Hi-Intensity Quartz Lamps, which produce higher UV intensity than typical Quartz Lamps.

Sanuvox Lamps are 19 mm in diameter, not 15 mm like other UV manufacturers.

The Getter

The Getter is incorporated into the Lamp.
More environmentally friendly. Uses less than ½ the amount of mercury used in other Lamps.
Designed to absorb pollutants inside the Lamp which are created as the Lamp burns.
Better maintains UV intensity and Lamp Life

Anode

Designed to easily ignite the mercury vapor for less strain on the filaments as the Lamp

starts.

Two Factors in achieving a high bacteria kill are :

The INTENSITY of the UV source and
The greater the INTENSITY the greater the kill.
The length of TIME the bacteria is exposed to the UV light
The more TIME the bacteria is exposed to the UV light, the higher the UV dosage it receives,
the greater the kill.

Intensity

The Bio-Wall increases its intensity through the use of Reflection.

The same way a flashlight or car's headlight uses a reflector to intensify and direct light. The

Sanuvox Bio-Wall uses five Aluminum Parabolic Reflectors to intensify the UV Energy.

=

Anodized Parabolic Reflectors and reflective materials such as REFLECTIX® greatly increases UV intensity

How powerful would a flashlight be without a reflector?

Dwell Time

How does the Bio-Wall increase the TIME the contaminants spend in contact with the UV Lamp?
The longer the UV Lamp, the more time the contaminants spend in contact with the UV Energy.
This compensates for the fact that Sanuvox is not slowing the air down as it passes over the lamp.
b) To increase the dwell time (the time the contaminant is in contact with the UV Energy), the purifier is mounted parallel to the air-stream not perpendicular, maximizing the time the contaminant is in contact with the UV lamp.

That's what the Bio-Wall is designed to do. Increase the TIME the contaminant is in contact with the Lamp so it can be irradiated by the UV Energy. The more time in front of the lamp, the higher the UV dosage the contaminant receives, the higher the kill.

Dwell Time

Bird’s Eye Example – The longer the Air is in contact with

the UV,the greater the UV dosage the contaminants receive

Typical Installation Bio-Hazard Installation

Example: For a 94% kill in a 36” x 36” duct, with the air moving @ 700 FPM. The % Kill is based on Mycobacterium tuberculosis.

The UV Bio-Wall is 60 inches long.

Generic Bio-Hazard Installation on a 36” x 36” Duct @ 700CFM

For a Biohazard installation, each Bio-Wall should be installed 9 inches from the duct walls. Each Bio-Wall will be 18” center to center from an adjacent Bio-Wall.

Biological contaminants vary in UV dosage needed to destroy them. Calculations are based on

contaminant's individual UV dosage required, air velocity, duct size, intensity and length of Bio-Wall.
