External Service Platforms

External Platform at Louver Face

Every external platform is preassembled and pre-fitted at the factory to ensure that every component will fit and function exactly as described. The platform will ship secured in the basin and attach quickly in the field with minimum fasteners. Platforms, ladders and safety cages can be added at the time of order or as an aftermarket item.

Safety gates are available for all handrail openings. All components are designed to meet OSHA requirements.

Ladder, Safety Cage, Gate and Handrails (FXV-288 and 364 Models Only)

In the event the end-user elects to provide access to the fan deck, models FXV-288 and 364 can be furnished with ladders extending from the top of the unit to the base, as well as safety cages, safety gates, fan deck extensions and handrail packages. All components are designed to meet OSHA requirements.

Note: Partial or full grating above the coil air intake is recommended with this option.

Internal Ladder

Internal Ladder and Service Platform

For access to the motor and drive assemblies on single air inlet models, a movable internal ladder is available.

Internal Service Platforms

For access to the motor and drive assemblies on single air inlet models and all dual air inlet models, an internal ladder and upper service platform with handrails is available. Safety gates are available for all handrail openings. All components are designed to meet OSHA requirements.

Vibration Cutout Switch

A factory mounted vibration cutout switch is available to effectively protect against equipment failure due to excessive vibration of the mechanical equipment system. BAC can provide either a mechanical or solid-state electronic vibration cutout switch in a NEMA 4 enclosure to ensure reliable protection. Additional contacts can be provided on either switch type to activate an alarm.

Positive Closure Damper (PCD) Hoods

The FXV’s innovative design results in a low heat loss when the unit is idle. When additional heat loss prevention is desired, coil air intake hoods with factory mounted PCDs with stainless steel linkages and damper actuators can be provided. The motor actuators are easily accessible. The addition of factory mounted insulation to the hood and casing further reduces the heat loss by minimizing losses due to conduction.

Basin Heaters

Basin Heater

Closed circuit cooling towers exposed to below freezing ambient temperatures require protection to prevent freezing of the water in the cold water basin when the unit is idle. Factory-installed electric immersion heaters, which maintain +40°F (4.4°C) water temperature, are a simple and inexpensive way of providing such protection.

Heater kW Data

Note: The table data is based on 460V/3 phase/60HZ power and standard, single-cell configuration

Electric Water Level Control Package

Electric Water Level Control Package

The electric water level control replaces the standard mechanical make-up valve when a more precise water level control is required. The electric water level control incorporates a troubleshooting LED to help diagnose water/probe conditions. This package consists of a conductance-actuated level control mounted in the basin and a solenoid activated valve in the make-up water line. The valve is slow closing to minimize water hammer.

Extended Lubrication Lines

Grease Fittings at the Access Door (inset) and Bearings with the Extended Lubrication Line Option

Extended lubrication lines are available for lubrication of the fan shaft bearings. Grease fittings are located inside the plenum area next to the access door.

High Temperature Fill

Optional high temperature fill material is available for high spray water temperatures up to 135˚F (57.2˚C).

Top Mounted Sunlight Shades

The corrosion resistant shields are mounted above the spray distribution system and help to smooth the airflow into the coils for optimum thermal performance. They also prevent strong wind from carrying the spray water out of the unit and can also block sunlight in locations previously susceptible to algae growth.

Basin Sweeper Piping

Basin Sweeper Piping

Basin sweeper piping provides an effective method of preventing debris from collecting in the cold water basin of the tower. A complete piping system, including nozzles, is provided in the tower basin for connection to side stream filtration equipment (by others).
