BAC – A Global Leader in Cooling Technologies and Solutions

BAC is committed to continuous innovation in technology and product development, ensuring that customers are provided with advanced solutions to meet ever-evolving market demands.

To address the needs of small- to medium-sized projects, especially those requiring low installation cost and simplified maintenance, BAC proudly introduces the Smart Series Cooling Tower — a compact, high-performance solution designed to exceed customer expectations.

Key Features

• Compact modular design for flexible site layout

• Fully assembled for standard delivery

• CTI certified across the entire product line, ensuring 100% thermal performance

• Fully compliant with GB noise standards, with noise levels as low as 61 dB(A)

• National CQC-certified for water conservation, with drift rate as low as 0.00092%

• Standardized with external ladder and hot water basin cover

• All safety features fully comply with both U.S. OSHA and China GB standards

Easy Installation

• All BAC Smart Series cooling towers are shipped fully assembled, allowing for complete lift-in-place installation. This ensures high installation quality while reducing on-site labor time.

• The Smart Series is specially engineered with a robust yet simplified structure that minimizes the number of components. The integrated cold water basin requires no field assembly. For projects requiring knock-down installation due to site constraints, on-site labor is significantly reduced.

Safe and Simple Maintenance

• All safety accessories comply with OSHA (Occupational Safety and Health Administration) standards.

• Standard galvanized steel ladder with optional safety cage and guardrail for easy access to the tower top.

• Hot water basin cover included as standard, capable of withstanding a concentrated load of 91 kg, enabling safe maintenance access.

• Split bearing design allows easy lubrication and replacement.

• Lightweight aluminum belt pulleys are easy to remove and resistant to corrosion.

• Large access doors and internal walkways facilitate maintenance of internal components.

Environmentally Friendly

Water-Saving

• Certified for water conservation, maximizing water resource utilization.

Low Noise Operation

• Standard and high-efficiency low-noise fan options are available, both meeting stringent national noise regulations.

• Industry-leading selection software provides reliable sound power and sound pressure level data for system design.

Guaranteed Thermal Performance

• All Smart Series products are CTI-certified, ensuring that thermal performance meets project requirements.

• Performance is verified through rigorous CTI certification processes and annual audits, guaranteeing 100% compliance with design specifications.

Year-Round Reliability

• Constructed with high-spec G235 galvanized steel frames and panels for superior strength and corrosion resistance.

• Equipped with dedicated waterproof bearings designed for cooling tower operation.

• Aluminum fans offer longer service life and greater reliability than standard FRP fans.

• Corrosion-resistant aluminum belt pulleys reduce wear and extend belt life.

• Standard hot water basin cover prevents debris from entering the system, ensuring dependable operation.

• Seamless integrated cold water basin effectively reduces the risk of leakage.

Construction Materials

Standard Structure
BAC uses high-specification G235 galvanized steel for frames and panels to ensure long service life of the cooling tower.

Drive System

The fan drive system supplies sufficient airflow and discharges heat into the atmosphere. All BAC drive systems are equipped with motors specifically designed for the hot and humid conditions of cooling towers. These motors feature permanently lubricated bearings, significantly reducing maintenance costs.

Optional:

• Vibration Cut-Off Switch

• Extended Lubrication Tubes

Large Integrated Cold Water Basin

The cold water basin collects water from both the cooling tower and system piping when the unit is shut down, and provides the necessary head for the circulation pump. BAC’s sloped basin design eliminates stagnant zones during operation, reducing microbial growth. The seamless integrated basin prevents debris and microorganisms from accumulating at joints, making cleaning easier.

Standard:

• Mechanical Water Level Control Assembly

Optional:

• Basin Heater

Multiple-Cell Configuration

Special measures are required to balance basin water levels across multiple units. Without proper balancing, one cell may overflow while another continues to refill, wasting water. BAC offers balance pipe options to ensure proper water level equalization among units.

Water Distribution System

BAC Smart series cooling towers use a gravity-fed distribution system. The patented nozzle layout is customized to the project’s flow rate, ensuring efficient and uniform water distribution.

Shipping & Rigging

The BAC Smart series offers two shipping options to meet various installation needs:

• Standard: Fully assembled shipping

• Optional: Knock-down shipping

Sound Attenuation Options

Cooling tower noise has become an increasingly important design factor. BAC offers a wide range of cost-effective noise reduction solutions to meet various project requirements. Both standard and low-noise fan options comply with national GB noise standards.

Fan Options:

• Standard Fan

• Low-Noise Fan (Optional)

Maintenance Access Options

BAC cooling towers offer comprehensive maintenance access features, all compliant with OSHA safety standards.

Standard:

• Internal Maintenance Walkway

• External Ladder with Optional Safety Cage and Guardrail
