1 . H e a l t h i e r a i r

Mold in buildings is a known health threat. Mold and other

microorganisms grow on damp cooling coils and in drain pans.Air flowing through coils and across drainpans spreads mold spores and mycotoxinsthroughout buildings where they can landand multiply on moist surfaces. To do allyou can to eliminate this threat, kill moldand other microorganisms on cooling coilsand drain pans with ultraviolet light in theC bandwidth (UVC). Continuous UVC exposure, provided byDRISTEEMs UV Germicidal Systems, keeps coils and drain pansclean and keeps mold spores out of the airstream.

2 . S a v e e n e r g y

A coil with very small amounts of mold growth can significantlyblock airflow and decrease coil thermaltransfer. The coil may look clean to thenaked eye, but there still can be enoughmold coating a cooling coil to reducesystem efficiency. As mold growth on acoil increases, energy costs increase due toreduced coil efficiency.

3 . R e d u c e m a i n t e n a n c e

Cleaning coils by hand exposes maintenance staff to strongchemicals and mold mycotoxins, which can cause severe healthproblems. Pressure-washing coils can push mold into the coilinterior, reducing coil function or requiringcoil replacement. Removing coils tosubmerge them until clean sometimesworks; however, it is a very expensive wayto clean coils.

Theres a much easier and more effectiveway to keep coils clean.

UV Germicidal Systems clean dirty coils and drain pans and keepthem continuously clean. Just replace the lamps annually andeliminate the periodic need for cleaning toxic coils by hand. UVGermicidal Systems applied to new coils maintain operation at peakperformance.

Where should you install UVC?Mold spores are everywhere in our homesand work places. We co-exist comfortablywith mold when their populations aresmall; however, when mold spores f ind afavorable environment, they multiply tothe point where they can cause healthproblems.

To multiply, mold spores need moisture anda food source. While there are many placeswithin a building where mold can grow,mold thrives on damp cooling coils with

dust as its food source.Good filtration helps, and prevents somemold growth, but will not eliminate it.

And, its extremely important to kill moldon coils to prevent spores from spreadingthroughout the building via the airstream.This is why we recommend installing UVClights to illuminate all cooling coils.

Q:What types of buildings need a UVGermicidal System?

A:Any building with a damp or wetcooling coil.

DRISTEEM performance and reliability

Customers all over the world rely on DRISTEEM performance

and reliability. Proven in thousands of installations, youllfind DRISTEEM humidifiers at NASA, high-tech facilities,world-famous museums, and the White House. Now, thatsame engineered performance and reliability is available inDRISTEEMs UV Germicidal Systems.

Solutions that precisely fit your application

DRISTEEM has a UV solution for every cooling coilapplication, including:

Large AHUs Small AHUs Packaged rooftop units

From systems installed right out of the box to systems designedfor a uniquely sized AHU, youll find the right UV solution atDRISTEEM.

Efficient operation

An effective ultraviolet treatment is a factor of intensity aswell as exposure time. Rely on DRISTEEMs UV GermicidalSystems to provide the required amount of ultraviolet light tokill microorganisms on coils. Polished aluminum reflectorson Model UVR enhance this efficiency by focusing ultravioletenergy at the coil and drain pan.

Easy installation and servicing

DRISTEEM UV Germicidal Systems are easy to install andservice. Model UVR is pre-assembled and ready to mount onsupport channels. Just connect power to the terminal strips.Other models ship with mounting hardware. Model UVRfixtures rotate away from the coil for easy service access (seeFigure 4-1).

M o r e a b o u t m o l d

Mold spores are everywhere and grow where there is water and food such as dust, paper

or wood. In buildings, molds thrive on dark, damp cooling coils and on moist paper orwood building materials such as wall board.

All molds can cause allergic reactions in humans and many produce mycotoxins.

Mycotoxins can be found in air, mold spores, within mold itself, and in the material where

mold is growing. Some common indoor molds such as aspergillus and penicillium can

cause a severe, sometimes toxic, reaction in humans. At low normal background levels,

mold is only a minor issue for many. Unmanaged, mold can be a serious health issue.

Ultraviolet light (C band) emitters

shall be incorporated downstream of

all cooling coils and above all drain

pans to control airborne and surface

microbial growth and transfer.

Components (see Figure 6-1)

1. Rotating lamp fixture

The lamp fixture rotates away from the coil,allowing easy access for lamp replacement(see also Figure 4-1 on Page 4).

2. Hinge with quick release pin

To rotate the lamp fixture, simply pull thequick release pin from the hinged bracket(see also Figure 4-1).

3. Ballast

Program-start ballast provides precise lampfilament preheat, optimizing lamp life.Operates with the following voltages: 120,208, 240, and 277 VAC.

4. Lamp

High output ultraviolet (UVC) lamp killsmold, bacteria, and all other microorganismson coils and drain pans.

5. Reflector

Polished aluminum reflector focuses UVCenergy.

6. Terminal strip

The terminal strip, located behind the easilyremoved key-holed cover, provides accessfor quick field electrical connections.

7. NEMA-12 electrical enclosure

The electrical enclosure houses an electronic

timer that monitors lamp usage andilluminates an indicator light after 9,000hours of use to signal required lampreplacement. A dry contact closes when thelamps need changing and sends a signalto a remote indicator light or buildingmanagement system (provided by installer).

8. Support channel (optional)

The lamp fixture attaches easily to standardhole-punched channel supports, which canbe provided by DRISTEEM if requested,shipped loose.

9. Door interlock safety switch (optional;

not shown)Recommended for installation on anydoor with access to a UVC lamp, the doorinterlock safety switch turns off the UVClamp when the door it is installed on opens,preventing accidental exposure. The switchrequires manual reset.

Installing Model UVR

Install Model UVR on the coils downstream side 12" to 24"(305 mm to 610 mm) from the coil (12" [305 mm] recommended).Placement on the coils downstream side produces the most

effective results because the downstream side tends to be the wetterside, enabling mold growth. In addition, the coils downstream sidetypically has more access room, allowing easier servicing.

Notes:

Obstructions between lamps and the coil will block illuminationand reduce Model UVRs effectiveness.

Contact DRISTEEM for instructions when placing a dispersionunit downstream of a UV Germicidal System.
