Uni-Guard Filter Diffuser

The U.S. Government (NIOSH) recommends that filtration systems be enhanced to remove hazardous air borne contaminants (See NIOSH Publication 2003-136). Uni-Guard™ is the most cost-effective enhancement method available. recommends that filtration systems be enhanced to remove hazardous air borne contaminants (See NIOSH Publication 2003-136). Uni-Guard™ is the most cost-effective enhancement method available.

The unique design of Uni-Guard™ Ceiling Filter-Diffuser Units makes possible a revolutionary value-added concept in Air Filtration and Air Diffusion.

Uni-Guard™ ceiling filter-diffuser units enable high-efficiency, sub-micron filters to be applied in a central fan system at the room air supply outlets. This is the ideal location to provide maximum overall system filtration effectiveness without increasing fan energy costs. Uniform air motion within the occupied space “sweeps” contaminates to the filters and provides draft free thermal comfort at higher energy saving thermostat settings.

Uni-Guard™ ceiling filter-diffuser units are especially suitable for the enhancement of existing central fan filtration systems, but may also be used with new systems.

Installation of Uni-Guard™ ceiling filter-diffuser units is simple, replaces old conventional diffusers, and does not require modifications of duct work or equipment rooms. The units may be installed incrementally, over time, without shutting the system down.

Uni-Guard™ results can be measured immediately after the installation of a single unit. The occupants will see and feel the improvement.

Warren’s breakthrough design in air flow throttling control offers superior acoustical, laminar flow and controllability characteristics. The Zebra® precision air valve may be used to regulate or balance air flow in ducted HVAC systems, air handling units, economizer sections, outside air intakes, or VAV applications. The Zebra® air valve assembly is compact and modular for easy installation and service, and can be mounted in almost any ducted system. Structural integrity of the Zebra® air valve is enhanced by the pleated accordion design and integral heavy gauge frame construction.

The effects of stratification have long been a concern to mechanical systems designers and building engineers. The Zebra® precision air valve offers laminar airflow throughout its entire throttling range. This ensures even air distribution over the entire cross-sectional area of the heating coil and/or supply duct.

The Zebra® precision air valve’s patented slide plates and direct-drive actuator mechanism provide precise throttling control. Due to its linear stroke and tight drive mechanism, Zebra®‘s slide plate design dramatically reduces linkage hysteresis and slide loading commonly found in conventional dampers. The actuator stroke (travel) is linear with its free area opening which provides more accurate control at low flows.

Noise attenuation is accomplished by the use of an array of evenly distributed precision orifices. This pattern creates a “muffler effect” that produces higher frequency noise as opposed to lower frequency noise associated with conventional dampers, which is very difficult to attenuate. The Zebra®‘s design is inherently quieter than single or opposed blade damper configurations.

2015 the 13 & 17-Year Periodical Cicadas Emergence in Kansas & Missouri

April 22, 2015 UPDATES (see below)

Emergence of the Missouri & Kansas Periodic Cicada Broods

Air Solution Company’s patented Air Intake Filters for cooling tower applications will provide the protection you need. For more information, pricing or to contact us CLICK HERE

Cicadas affect campus cooling systems Wednesday, Jun. 1, 2011 — 2:39 PM

13 & 17 Year Periodical Cicada Broods are known to be as large as a BILLION per square mile and are a nuisance for 6-8 weeks.

Cicadas are attracted by the sound of cooling towers and can easily inundate the fill, sump, strainer, piping, pumps and chillers. Air intakes of other equipment can also be affected.

UPDATES:

Brood IV, the Kansan brood, will emerge in Texas, Oklahoma, Missouri, Kansas, Nebraska, and Iowa, in the spring of 2015.

The cicada species that will emerge are Magicicada cassinii (Fisher, 1852), Magicicada septendecim (Linnaeus, 1758), and Magicicada septendecula Alexander and Moore, 1962. These periodical cicadas have a 17-year life cycle. The last time they emerged was 1998.

2015 Kansas & Missouri: 17 Year Magicicada Brood IV

Missouri Counties Affected: Atchison, Barton, Buchanan, Caldwell, Clay, Clinton, Daviess, Dekalb, Gentry, Grundy, Harrison, Holt, Jackson, Johnson, Lafayette, Livingston, Mercer, Nodaway, Pettis, Ray, Saline, Vern, and Worth

Kansas Counties Affected: Allen, Anderson, Atchison, Bourbon, Butler, Chase, Cherokee, Coffey, Crawford, Doniphan, Douglas, Geary, Greenwood, Johnson, Labette, Linn, Lyon, Marion, Montgomery, Neosho, Osage, Pottawatomie, Riley, Saline, Sumner, Wilson, Woodson, and Wyandotte CLICK HERE FOR MAP

2015 Missouri: 13 Year Magicicada Brood XXIII

Missouri Counties Affected: Andrew, Barry, Bates, Bollinger, Boone, Camden, Cape Girardeau, Cedar, Christian, Clark, Cole, Cooper, Crawford, Dade, Dallas, Douglas, Franklin, Henry, Hickory, Howard, Howell, Jefferson, Knox, Laclede, Lawrence, Macon, Maries, Mississippi, Montgomery, Morgan, Newton, Ozark, Pemiscot, Perry, Pettis, Polk, Randolph, Scott, Shannon, Ste.

These bugs are harmless, except to your cooling towers

and other mechanical equipment air intakes.

They are attracted to the sound of cooling towers,

get sucked in plugging the fill, strainers and sump.

They contaminate the cooling tower water.

Their soft tissues breakdown feeding and escalating the bacterial level

and they absorb water treatment chemicals.

Their hard exoskeleton does not breakdown in the water

or by water treatment. They have to be physically removed

from the fill, sump and strainers

They can plug up other equipment and AHU air filters, as well.

You can protect your cooling towers and other

susceptible equipment with patented Air Intake Filters

from Air Solution Company. And this is a good time to do it,

while there time to order and install the filters.

By keeping these bugs and other airborne debris (like cottonwood seed) out of your HVAC systems, you will avoid all the headaches and high maintenance and labor costs.

Dead Cicadas Cause Problems At Metro Schools

“Teams will be out inspecting all 88 cooling towers across the district. More sub-contractors will be hired to handle the clean-up. Seven crews will be out daily. Each of those crews will be cleaning about eight to ten towers a day.”

Consider the cost of this:

88 cooling towers, 7 crews, 14 people in the field, $80/hour contract labor, 40 day duration = $224,400 or $2,545 / tower to remove the Cicadas and keep the chiller plants operating, otherwise they shutdown.

This is the calculated cost to vacuum and skim the bugs out of the sump, fill and strainers does not include added water treatment, higher water and energy costs or additional maintenance due to high head conditions. For example a 1° higher condenser water temperature entering a 250 ton chiller operating at .60 kW/ton at 79% load, 16 hrs/day, 214 days/year = 3% inefficient or $1,450/yr.per chiller.
