FXV Custom Features & Options››Coil ConfigurationsBAC offers a large selection of coil configuration options to fulfill anythermal and pressure drop requirements. STANDARD SERPENTINE COILThe standard cooling coil is constructed of continuous lengths of allprime surface steel. The coil is hot-dip galvanized after fabrication(HDGAF) to apply a thick zinc corrosion barrier over the entireexterior surface of the coil. The coil is designed for low pressuredrop with sloping tubes for free drainage of fluid. Each coil ispneumatically tested at 375 psig (2,586 kPa) and is fabricated perASME B31.5 standards to ensure the highest quality and integrity.Standard Coil ConstructionCustomerValued LOW PRESSURE DROP COIL DESIGNSMultiple coil configurations have been designed by BAC and areavailable to meet all system pressure drop requirements. A higherpressure drop across the coil requires greater system pumping energyand therefore increases operating costs. These coil configurationsdrastically reduce pressure drop while ensuring the highest thermalperformance. CLEANABLE HEADER COIL (OPTION)The cleanable header tube bundle provides removable cover plateson the inlet and outlet header boxes to permit access to eachserpentine tube circuit for solvent or air-pressure cleaning.

FXV Custom Features & Options››Drive System OptionsVEBAC5ROTO & DRIM W YEAR YARRANT The fan drive system provides the cooling air necessary to rejectunwanted heat from the system to the atmosphere. All BAC drive systemsuse premium efficient cooling tower duty motors and include BAC’scomprehensive 5-year motor and drive warranty. Cooling tower dutymotors are specially designed for the harsh environment of a coolingtower and have permanently lubricated bearings, drastically decreasingthe maintenance requirement of the motor. BAC belt drive systemsare the most durable and maintenance friendly drive systems on themarket, including single nut adjustment for belt tensioning to make belttensioning simple.CustomerValued STANDARD BALTIDRIVE POWER TRAINThe BALTIDRIVE Power Train utilizes special corrosion resistantmaterials of construction and state-of-the-art technology to ensureease of maintenance and reliable year-round performance. This BACengineered drive system consists of a specially designed powerbandand two cast aluminum sheaves located at minimal shaft centerlinedistances to maximize belt life. As compared to a gear drivesystem, this specially engineered belt drive system provides manyadvantages. The BALTIDRIVE Power Train requires only periodicinspection of components and belt tensioning, which is simplewith a single nut adjustment, and requires less downtime. Only fanbearing lubrication is required for routine maintenance. Belt drivesystems also have the added advantage of being suitable for variablefrequency drive (VFD) applications without requiring expensiveoptional accessories.BALTIDRIVE Power Train Fan SystemCustomerValued INDEPENDENT FAN OPERATION (OPTION)Models FXV-0809, FXV-0812, and FXV-1212 are provided withone fan motor driving two fans.

BALTIGUARD FAN SYSTEM (OPTION)The BALTIGUARD Fan System consists of two standard singlespeed fan motor and drive assemblies. One drive assembly issized for full speed and load, and the other is sized approximately2/3 speed and consumes only 1/3 the design horsepower. Thisconfiguration provides the reserve capability of a standby motor inthe event of failure. As a minimum, approximately 70% capacitywill be available from the low horsepower motor, even on adesign wet-bulb day. Controls and wiring are the same as thoserequired for a two-speed, two-winding motor. Redundant motorsare available by increasing the size of the standby fan motor ofthe BALTIGUARD Fan System to the size of the main motor.This provides 100% motor redundancy and the greatest level ofreliability.BALTIGUARD Fan SystemUsed for VFD Applications BALTIGUARD PLUS FAN SYSTEM (OPTION)The BALTIGUARD PLUS Fan System builds on the advantagesof the BALTIGUARD Fan System by adding a variable frequencydrive (VFD) to either the pony or the main motor, depending onsystem requirements. This offers the benefits of additional capacitycontrol and energy savings, along with the redundancy offered bythe BALTIGUARD Fan System. Alternatively, a VFD can be addedto both the pony and main motor for complete capacity control andredundancy under any load.

FXV Custom Features & Options››Cold Water BasinThe spray water collects in the cold water basin which is pumped backover the heat transfer coil. During operation, the FXV cold water basinhelps eliminate any stagnant water zones, which are susceptible tobiological growth. STANDARD MECHANICAL WATER LEVEL CONTROLMechanical make-up valves must operate continuously in the moistand turbulent environment existing within evaporative coolingequipment. Due to this environment, the operation of the valvemust be simple, and the valve must be durable. BAC’s high qualitymechanical water level control assembly is standard with all units,and has been specially designed to provide the most reliableoperation while being easy to maintain. This accessory is omitted forremote sump applications.Mechanical Water Level ControlCustomerValued ELECTRIC WATER LEVEL CONTROL (OPTION)BAC’s Electric Water Level Control (EWLC) is a state-of-the-artconductivity actuated, probe type liquid level control.

FXV Custom Features & Options››Air Intake and Discharge OptionsIn a closed circuit cooling tower, airborne debris can be entrained inthe water through the unit’s air intake. The FXV has several options forair intake accessories that prevent debris from entering the system andmaintain even unobstructed flow through the unit. Reducing the amountof debris that enters the tower lowers maintenance requirements andhelps to maintain thermal efficiency.CustomerValued COMBINED INLET SHIELDS (CIS)The Combined Inlet Shields’ (CIS) bent flow path blocks sunlightfrom the cold water basin and fill section and acts as a screen toprevent debris from entering the unit. These benefits result in asignificant reduction in algae growth, debris accumulation, and scalebuild-up. CIS are constructed from corrosion and UV resistant PVC,are CTI certified, and are installed in easy to handle sections that areseparate from the fill section to facilitate removal, inspection, andreplacement. The use of CIS results in lower maintenance costs andease of maintenance over the life of the unit.Combined Inlet Shields PCD HOODS AND INSULATION (OPTION)The innovative design of BAC closed circuit cooling tower’s resultsin a low heat loss when the unit is idle. When additional heatloss prevention is desired, PCDs with stainless steel linkages anddamper actuators can be provided. The motor actuators are easilyaccessible. The addition of factory mounted insulation to the hoodand/or casing further reduces the heat loss by minimizing losses dueto conduction. Per ASHRAE 90.1-2010 either an automatic 3 wayvalve or PCDs are required on Closed Circuit Cooling Towers used onheat pump applications when used in heating applications.CustomerValued SUNSCREENS (OPTION)C27The corrosion resistant SunScreens are mounted above the spraydistribution system and help to smooth the airflow into the coils foroptimum thermal performance. They also prevent strong winds fromcarrying spray water out of the unit and block sunlight in locationspreviously susceptible to algae growth.
