All Information is per Unit

Quantity: 2 Model VFL-036-31K CLOSED CIRCUIT COOLING TOWER

Unit Type:

Factory fabricated, forced draft, counterflow closed circuit cooling tower with vertical discharge.

Quality Assurance:

Each unit is manufactured under closely-controlled conditions using standardized parts to ensure each unit is built precisely to the same high-quality design and construction standards. The design, manufacture, and business processes of Baltimore Aircoil Company are ISO 9001:2000 certified.

Unit Efficiency:

The unit(s) complies with the energy efficiency requirements established by ASHRAE Standard 90.1-2010.

CTI Certification:

The thermal performance is certified by the Cooling Technology Institute in accordance with CTI Certification Standard STD-201.

Materials of Construction:

Heavy gauge panel construction of Type 304 stainless steel utilizing double break flanges for maximum strength, rigidity, and reliable sealing at watertight joints. Circular access doors provided for interior inspection, cleaning, and adjustments are constructed of Type 304 stainless steel and are held in place with phenolic knob screws. The heat transfer casing section is contructed of Type 304 stainless steel.

The fan(s) is located in the dry air stream to provide greater reliability and ease of maintenance. Fan wheels are forwardly curved, centrifugal, squirrel-cage type which are statically and dynamically balanced, and are mounted on a steel shaft supported by heavy-duty, self-aligning, relubricatable bearings with cast iron housings. Fan housings have curved inlet rings for efficient air entry and are constructed of Type 304 stainless steel. The fan housings are of split design to facilitate fan wheel and shaft removal.

V-belt sheaves, selected for 150% motor nameplate horsepower, are mounted and aligned at the factory. Drive and all moving parts are protected by removable screens and panels made of Type 304 stainless steel. The fan(s), fan shaft(s), bearings, mechanical equipment support and fan motors are warranted against defects in materials and workmanship for five (5) years from date of shipment.

Fan Wheels:

Forwardly curved, centrifugal, squirrel cage type fan wheels are constructed from G-235 (Z700 metric) hot-dip galvanized steel protected with the BALTIBOND® Corrosion Protection System. Fan wheels are statically and dynamically balanced. Fan housings have curved inlet rings for efficient air entry.

Coil Type:

Continuous 1.05" (27 mm) O.D. all prime surface Type 304 stainless steel encased in steel framework. Coil will be designed for free liquid drainage. Coil has a maximum allowable working pressure of 300 psig (2170 kPa) and is tested at 375 psig (2685 kPa) air pressure under water.

Drift Eliminators:

Drift eliminators are constructed of polyvinyl chloride (PVC), and are removable in easily handled sections. They impart three distinct changes in air direction to effectively strip entrained moisture from the leaving airstream with minimum air resistance. PVC eliminators are not a working surface. A working platform by others may be required to service the water distribution system.

Unit Anchorage:

When supported as recommended, the unit will have anchorage to resist wind loads up to 30 psf (146.6 kg/m^2) acting on the full vertical projected area with 16 psf (78.1kg/m^2) acting simultaneously on the full horizontal projected area or seismic forces of 161% of the operating weight acting in the horizontal direction, and 24% of the operating weight acting in the vertical direction applied at the center of gravity.

Spray Water Pump Assembly:

Basin has integral pump(s) with large area, lift out, steel strainer screen(s) including perforated openings sized smaller than the water distribution nozzle orifices. Strainers include anti-vortexing baffles to prevent air entrainment. Close-coupled, bronze-fitted pump(s) with mechanical seal is mounted on the basin. The pump motor(s) are totally enclosed, fan cooled (TEFC). A water bleed line with a metering valve to control the bleed rate is installed between the pump discharge and the overflow connection. Electrical requirements match fan motor.

Spray Distribution System:

Spray header with schedule 40 PVC branches. Removable branches and 360° spray pattern plastic spray nozzles are held in place with snap-in rubber grommets.

Basin Water Level Control:

A make-up valve with unsinkable polystyrene filled plastic float arranged for easy adjustment. The corrosion resistant make-up valve is suitable for water supply pressures between 15 psig (103 kPa) and 50 psig (345 kPa).
