Service Platforms

External Platform at Louver Face

Standard Internal Walkway

Internal Ladder and Service Platform

For access to the motor and drive assemblies on Models 15296 through 15425, an internal ladder with or without upper service platform with handrails is available. For external service, louver face platforms and access door platforms are options that can be added to the cooling tower either when the unit is purchased or as an aftermarket item. Safety gates are available for all handrail openings supplied by BAC. All components are designed to meet OSHA requirements.

Vibration Cutout Switch

A factory mounted vibration cutout switch is available to effectively protect against rotating equipment failure.  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.  Remote reset capability is also available on either switch type.

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.

Electric Water Level Control Package

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

The electric water level control replaces the standard mechanical make-up valve when a 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 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 120°F (48.9°C) is anticipated, an optional high temperature fill material is available which increases the maximum allowable entering water temperature to 135°F (57.2°C).

Air Inlet Screens

Wire mesh screens are available factory-installed over the air inlet louvers to prevent debris from entering the tower.

Basin Sweeper Piping

Basin sweeper piping is an effective method of eliminating sediment that may collect in the cold water basin of the tower. A complete piping system, including nozzles, is provided in the tower basin to connect to side stream filtration equipment (by others).  For more information on filtration systems, click here.

Side Outlet Depressed Sump Box

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.
