2 Units EVAPCO COOLING TOWERS AT 8 49B 2013
Please follow the link below for manufacturer specifications:
UNIT TYPE Factory assembled, induced draft, counter flow cooling tower.
CONSTRUCTION-

All cold water basin components including vertical supports and air inlet louver frames are constructed of Type 304 Stainless Steel. Heavy gauge mill hot-dip galvanized steel casing. Hot-dip galvanized steel channel and angle supports.

All galvanized steel is coated with a minimum of 2.35 ounces of zinc per square foot of area (G-235 designation). During fabrication, all galvanized steel panel edges are coated with a 95% pure zinc-rich compound.

All factory basin joints below the air inlet louver channel are welded for water tight construction.
PAN STRAINER* All type 304 stainless steel construction with large area removable perforated screens.
ACCESS Hinge mounted door in the upper casing for fan drive and water distribution system access. Removable louver panels on all four sides of the unit for pan and sump access.
FAN SHAFT Solid shaft of ground and polished steel. Exposed surface coated with rust preventative.
FAN SHAFT BEARINGS Heavy-duty, self-aligning ball type bearings with extended lubrication lines to grease fittings located on access door frame. Bearings are designed for a minimum L-10 life of 75,000 hours.
FAN(S) Fans are axial propeller type constructed of aluminum alloy and statically balanced. The fan is installed in a closely fitted cowl with venturi air inlet. Fan screens are galvanized steel and have steel frames bolted to the fan cowl.

FAN MOTOR Totally enclosed, ball bearing type electric motor(s) suitable for moist air service.
Motor(s) are Premium Efficient, Class F insulated, 1.15 service factor design.
Inverter rated per NEMA MG1 Part 31.4.4.2 and suitable for variable torque
applications and constant torque speed range with properly sized and adjusted variable frequency drives.
FAN DRIVE The fan drive is a multi-groove, solid back, reinforced neoprene V-belt type with taper lock sheaves designed for 150% of the motor nameplate horsepower. Fan and motor sheaves are constructed of aluminum alloy.
FILL Polyvinyl Chloride (PVC) of cross-fluted design. PVC sheets are bonded together for strength and durability. Fill is self-extinguishing for fire resistance, has a flame spread of 5 under A.S.T.M. designation E-84-81a, and is resistant to rot, decay and biological attack.
WATER DISTRIBUTION SYSTEM Precision molded ABS spray nozzles with a large orifice to eliminate clogging.
Spray header and branches are Polyvinyl Chloride (PVC) for corrosion resistance with steel connection to attach external piping.
ELIMINATORS The eliminators are constructed entirely of Polyvinyl Chloride (PVC) in easily handled sections. Design incorporates three changes in air direction and limits the water carryover to a maximum of 0.001% of the circulating water rate.
AIR INLET LOUVERS The air inlet louvers are constructed from UV inhibited polyvinyl chloride (PVC) and incorporate a framed interlocking design that allows for easy removal of louvers for access to the entire basin area for maintenance. The louvers have a minimum of two changes in air direction and are of a non-planar design to prevent splash-out, block direct sunlight and debris from entering the basin. (Patent Pending)
PASSIVATION All evaporative cooling equipment utilizing galvanized construction requires initial passivation to maximize the service life of the equipment. The sites water treatment vendor should be contacted several weeks prior to adding any water to the system to provide a passivation plan along with associated passivation plan costs.
ELECTRONIC WATER LEVEL CONTROL PACKAGE
Electronic water level control package with three (3) stainless steel water level
sensors ((1) one high level, one (1) low level and one (1) ground) with a NEMA 4X enclosure mounted in a cleanable Schedule 40 PVC external standpipe with slow closing solenoid Valve(s) and "y" strainer(s).
