Ladder, Safety Cage, Gate, and Handrails

In the event the owner requires easy access to the cooling tower fan deck, the Series 3000 Cooling Tower can be furnished with ladders extending from the top of the unit to the base, as well as safety cages, safety gates, and handrail packages. All components are designed to meet OSHA requirements. All access to the top of the equipment must be made in accordance with applicable governmental occupational safety standards.

External Service Platforms

For external service, louver face platforms, access door platforms, and fan deck extensions can be added to the cooling tower when the unit is purchased or as an aftermarket item. Safety cages and safety gates are also available. All components are designed to meet OSHA requirements.

Internal Walkway and Service Platform

A galvanized steel internal walkway is available to provide a permanent working surface for easy access to the strainer, outlet, and make-up water assembly. For access to the motor and drive assemblies on two-piece units, 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 to either switch type to activate an alarm.

Basin Heaters

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

The electric water level control replaces the standard mechanical make-up valve when more precise water level control is required. 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

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

High Temperature Fill

If operation above 130°F (54.4°C) is anticipated, an optional high temperature fill material is available which increases the maximum allowable entering water temperature to 140˚F (60.0˚C).

Factory Mutual Approval

All multi-cell Series 3000 Cooling Towers are available with Factory Mutual (FM) Approved construction as an option.

Equipment Controls

BAC control panels are specifically designed to work seamlessly with all BAC units and engineered to meet your particular application. A terminal box, available on Series 3000 Cooling Towers, includes a factory-mounted enclosure, factory wiring to terminal blocks for the fan motors and vibration cut-out switch, and grounding lugs.

Mechanical Equipment Removal

There are three types of mechanical equipment removal systems available. One will handle motors/gears weighing less than 900 lbs. The second will handle motors/gears weighing more than 900 lbs, and the last handles motors located outside the airstream.

Basin Sweeper Piping

Basin sweeper piping provides an effective method of preventing sediment 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).

Side Outlet Depressed Sump

A side outlet depressed sump box is available for field installation below the base of the tower to facilitate jobsite piping. The outlet connection is designed to mate with an ASME Class 150 Flat Face Flange. See the Connection Guide, for more information on standard and optional unit connection types.

Velocity Recovery Stacks

Velocity recovery stacks are available on the Series 3000 Cooling Tower for increased incremental thermal performance. This accessory can be used to gain extra capacity in tight layouts, while maintaining the same footprint and unit horsepower, as well as maintaining CTI certification. Field assembly is required.
