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.

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.
