Equipment Controls


Variable Frequency Drive

BAC control panels are specifically designed to work seamlessly with all BAC units and engineered to meet your particular application.

Low Sound Alternatives


Unit Shown with Sound Attenuation

The low sound levels generated by Series V Closed Circuit Cooling Towers make them suitable for most installations. For situations when one direction is particularly sound sensitive, the unit can be oriented so that the side opposite the air intake faces the sound-sensitive direction. The Series V is also available with factory designed, tested and rated sound attenuation for both the air intake and discharge.

External Access Options

(VF1 Models Only)

In the event the end-user elects to provide access to the top of the unit, VF1 models can be furnished with ladders extending from the base of the unit to the top, 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 government occupational safety standards.

NOTE: When these access options are employed, the unit must be equipped with steel drift eliminators.

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 activate an alarm.

Electric Water Level Control Package

The electric water level control replaces the standard mechanical makeup 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.

Basin Heaters

Basin Heater

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.

Extended Lubrication Lines

Extended lubrication lines with grease fittings located outside the fan section are available for lubrication of the fan shaft bearings.

Bottom Screens (VF1 Models Only)

Wire mesh screens are available factory-installed over the bottom openings to prevent unauthorized access.

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 piping system is provided for connection to side stream filtration equipment (by others).

Solid Bottom Panels


Solid Bottom Panels

Factory-installed bottom panels are required when intake air is ducted to the unit.

Discharge Hoods

Discharge Hood

Tapered Discharge Hood

BAC offers a full line of standard discharge hoods with and without positive closure dampers that are built, tested, and rated specifically for all Series V Closed Circuit Cooling Towers. The tapered hoods are designed to increase the discharge air velocity to avoid recirculation in extremely tight enclosures. Straight or tapered hoods can be used to elevate the unit discharge above adjacent walls. A larger fan motor may be necessary when this option is provided.
