Single Source Responsibility  

NEMA 3R VFD

BAC has designed the controls taking into consideration the exact specifications of the fan and spray pump motors, heaters and other accessories, providing you with a single source solution.

Indoor/Outdoor Applications

BAC offers a variety of enclosures for location flexibility; whether in a mechanical equipment room or outdoors next to the equipment.

Industrial Grade Components

NEMA contactors are provided with all BAC control panels (25 amps and above). Circuit breaker protection is provided for the main panel as well as separate circuit breakers for each motor or speed. Each control panel is UL/CSA listed.

Pre-wired Unit Mounted Terminal Box & VFD

BALTIGUARD PLUS™ Fan System Control

Easy Installation

All motor starters and basin heater contactors are modular in design, which simplifies expansion or replacement. The VFDs are constructed with 24VDC components, making them 70% lighter and easier to install than VFDs using 120V components. Also available are optional universal mounting kits and factory pre-wired unit mounted terminal boxes (Series 3000 Cooling Towers only) for ease of panel mounting and field wiring, saving time and money.

Compliance with Current Energy Standards

BAC Controls can help you comply with the speed control requirements of current energy standards such as ASHRAE Standard 90.1 and California Title 24. These standards call for any motor 7.5 HP and above to have the ability to run at 2/3 or less of full speed. BAC offers many alternatives to comply with this requirement, depending on your unique system needs. These methods include variable frequency drives, the BALTIGUARD PLUS™ Fan System, the ENERGY-MISER® Fan System, or multi-speed motors. The automatic motor speed control requirements of these standards can be satisfied through the controllers and temperature/ pressure sensors available with BAC Controls for any of these methods.

Saves Energy and Water

Evaporative water-cooled systems, whether for comfort cooling or process applications, offer substantial year-round system energy savings compared to air-cooled alternatives. Proper system control is crucial to fully utilize this advantage and operate your system at peak efficiency under all combinations of atmospheric and load conditions. BAC’s technical expertise in this field can show you how saving energy can also save you water when using BAC Controls for a truly “green” solution.
