NOTE:
Since the quality of the
ambient air and make-up water
varies significantly from job
site to job site, BAC strongly
recommends obtaining the services
of a competent water treatment
specialist prior to the initial
start-up of the evaporative cooling
equipment. Additionally, to protect
against the risk of Legionella
contamination, never operate
the cooling equipment without
adequate biological control.
BAC products are constructed of corrosion-resistant materials. The fill is made of a polyvinyl
chloride (PVC), which requires no protection against rot, decay, rust or biological attack.
Other materials listed below are used in the equipment construction:
•
Galvanized Steel Components
: Inspect the galvanized steel components for blemishes
or corrosion. Wire brush and recoat the affected areas with a cold galvanizing compound
such as zinc rich compound (ZRC).
•
Thermosetting Hybrid Polymer Components
: Inspect the galvanized steel components
protected with the thermosetting hybrid polymer for scratches, scrapes, or blemishes.
To cosmetically touch up these areas with color matched paint use BAC Part #160133
available from your local BAC Representative.
•
Stainless Steel Components
: Inspect stainless steel components for signs of blemishes
or corrosion. See “Long Term Care of Stainless Steel” on
page 25
for cleaning and care
instructions.
•
Fiberglass Reinforced Polyester (FRP) Components:
Series 3000 Cooling Towers
are provided with FRP casing panels as standard. Inspect the casing panels for
accumulation of dirt and clean them with soap and water as necessary.
•
TriArmor
®
Corrosion Protection System
: Inspect components protected with the
TriArmor
®
Corrosion Protection System for signs of deep scratches or blemishes,
especially in areas with field penetrations. Touch these up with 3M™ Windo-Weld™
Super Fast Urethane which is available through your local BAC Representative (BAC
Part # RK1015).
•
Pultruded Fiberglass Reinforced Polyester (PFRP) Components:
Series 3000 Cooling
Towers are optionally provided with PFRP hot water basins. Inspect the basin panels
for accumulation of dirt and clean them with soap and water as necessary.
Water Treatment
A proper water treatment program, administered under the supervision of a competent water
treatment specialist, is an essential part of routine maintenance to ensure the safe operation
and longevity of evaporative cooling equipment, as well as other system components.
In evaporative cooling products, cooling is accomplished by evaporating a small portion of
the recirculating water as it flows through the unit. As the water evaporates, the dissolved
solids, originally present in the water, remain behind and if not controlled, the concentration
of dissolved solids will increase rapidly. This can lead to corrosion, scale, or biological
fouling which may negatively affect heat transfer as well as the longevity of system
components. A water treatment program must control the following situations:
ATTENTION:
Neglected damaged
areas on the Whisper Quiet Fan can
result in the attack of the glass-
fiber layers (a process commonly
known as fiberbloom) because of
moisture entering through these
spots.
