Furnish and install EVAPCO Model(s) LRW _____ Counterflow, Blow-Through Closed Circuit Cooler with single side air entry to cool _____ GPM (L/S) of _____ from ___°F (ºC) to ___°F (ºC) with a ___°F (ºC) entering wet bulb temperature. Unit height shall not exceed _____ feet (meters). The cooler(s) shall operate against ____ w.g. external static pressure. Closed Circuit Cooler(s) shall be fully assembled with all moving parts factory mounted and aligned.

Cold Water Basin
The complete cold water basin shall be constructed of Type 304 stainless steel for long life and durability. Standard cold water basin accessories shall include Type 304 stainless steel overflow, drain, anti-vortexing hood, strainers, brass make-up valve with unsinkable, foam filled plastic float and wastewater bleed line with adjustable valve.

Casing and Fan Section
The casing and fan section shall be constructed of G-235 (Z-600 Europe) galvanized steel for long life and durability. Fan section shall include fans, motors and drives. The entire drive system (including fans, motors, sheaves and belts) shall be located in the dry entering airstream.

Centrifugal Fans and Drives
Fans shall be forwardly curved centrifugal type of hot-dip galvanized steel construction. The fans shall be factory installed, statically and dynamically balanced for vibration free operation. The fans shall be mounted on either a solid steel shaft or a hollow steel foam filled shaft with forged bearing journals. The fan shaft shall be supported by heavy-duty self-aligning bearings with cast iron housings and lubrication fittings extended to the outside of the unit for ease of maintenance. The fan drive shall be a V-Belt type with taper lock sheaves designed for 150% of the motor nameplate horsepower. Drives are mounted and aligned at the factory.

Fan Motor
Fan motor(s) shall be ___ Horsepower (kW) T.E.F.C. design with 1.15 service factor and suitable for outdoor installation on ___ volts, ___ hertz, and ___ phase electrical service. Motor(s) shall be mounted on an adjustable base with external belt adjustment.

Water Recirculation Pump
The pump shall be a close-coupled, centrifugal type with a mechanical seal. Pump motor shall be ___ Horsepower (kW) T.E.F.C. design suitable for outdoor installation on ___ volts, ___ hertz, and ___ phase electrical service.

Heat Transfer Coil
The coil(s) shall be all prime surface steel, encased in steel framework with the entire assembly hot-dip galvanized after fabrication. Coil(s) shall be designed with sloping tubes for free drainage of liquid and tested to 400psig (2758 kPa) air pressure under water.

Water Distribution System
The system shall provide a water flow rate of not less than 6 GPM over each square foot (4 liters per second over each square meter) of coil face area to ensure proper flooding of the coil. The spray header shall be constructed of schedule 40 polyvinyl chloride pipe for corrosion resistance. All spray branches shall be removable and include a threaded end plug for cleaning. The water shall be distributed over the entire coil surface by precision molded ABS spray nozzles (1” x 1/2” orifice) (25,4 by 12,7 mm) with an internal sludge ring to eliminate clogging. Nozzles shall be threaded into the spray header to
provide easy removal for maintenance.

Eliminators
The eliminators shall be constructed of inert polyvinyl chloride that has been specially treated to resist UV degradation. Assembled in easily handled sections, the eliminators shall incorporate three changes in air direction to assure removal of entrained moisture from the discharge airstream. The maximum drift rate shall not exceed 0.001% of the recirculated water rate.

Finish
The complete cold water basin shall be constructed of Type 304 stainless steel for maximum corrosion protection. The casing and fan section shall be constructed of G-235 (Z-600 Europe) heavy gauge mill hot-dip galvanized steel. During fabrication, all galvanized panel edges shall be coated with a 95% pure zinc compound.

Mechanical Equipment Warranty
The fan motor and drive system shall carry a (5) five year warranty from the date of shipment, against defects in materials and workmanship including the fan(s), bearings, sheaves, shafts, fan motors(s) and mechanical equipment supports.
