Inside the coil, high-temperature gaseous refrigerant exchanges heat with the spray water and air outside the coil, condensing from gas to liquid. The powerful induced draft fan ensures the spray water fully covers the coil surface. Driven by the airflow, the heat transfer effect is significantly enhanced.

After absorbing heat, the temperature of the spray water and air rises, and some of the water evaporates, carrying away a large amount of heat through latent heat of vaporization. The drift eliminators capture the moist warm air, collecting water into the PVC heat exchange layer.

Water in the PVC heat exchange layer is cooled by the passing air, reducing its temperature before entering the cold water basin. It is then pumped by the circulating water pump back into the spray system for continuous circulation.

Water lost by evaporation into the air is replenished via a float-operated water level control valve.

Under partial load conditions, the heat exchange capacity of the evaporative condenser can be adjusted by controlling fan speed or the number of operating fans.

Patented composite flow heat exchange technology ensures efficient operation with low refrigerant charge.
Concurrent airflow and water flow design prevents "dry spots" at the coil bottom, reducing scaling.
Circulating water exchanges heat within the fill layer, maintaining low spray water temperature.
Meets IBC seismic and wind load requirements; full product range tested at 2.4g seismic level and 167 psf wind load on vibration tables.

All products meet or exceed ASHRAE 90.1 energy efficiency standards.
Patented coil heat exchange design minimizes scaling risk, reducing corrosion and fouling.
High-efficiency and variable frequency motors are available as energy-saving options.
Various coil configurations support different fan motor power ratings to optimize energy use.
Independent drives are optionally available.

Lightweight equipment reduces hoisting and foundation costs.
Modular design shortens installation time.
Fewer coil connection pipes lower piping installation expenses.
Designed to utilize existing foundations effectively.

The choice of materials for the cooling tower maintenance structure depends on water quality, climate, environment, available maintenance resources, product lifespan, and budget. BAC offers practical solutions tailored to customer applications and budgets.

The enclosure and structure use imported ASTM-A653 “G235” galvanized steel plate.

Electrostatic coating on galvanized steel significantly improves corrosion resistance.

304 and 316L stainless steel panels are available, connected with stainless steel bolts.

Equipped with patented composite suspended fill made of PVC, designed for high heat transfer efficiency. PVC offers corrosion resistance and microbial protection. The fill is suspended from the cold water basin for easy cleaning. Low air flow resistance between fill layers ensures high efficiency.

Standard Fill
Suitable for spray water temperatures up to 54.4°C.
High-Temperature Fill (Optional)
Suitable for spray water temperatures up to 60°C.

Various coil options are available to meet different heat exchange and pressure drop requirements.

Made from continuous steel strips, each coil undergoes a 25-kg pressure test and hot-dip galvanizing for corrosion protection. Designed with a slope for proper drainage. Available in two-circuit standard and optional three-, four-, or six-circuit versions to reduce pressure drop.

Available in 304 and 316L stainless steel, pressure tested at 25 kg. Stainless steel coils may have slightly reduced heat transfer; please consult BAC sales.

For high-pressure applications, ASME-certified coils are available, complying with ASME Boiler and Pressure Vessel Code. Hot-dip galvanized and pressure tested at 2586 kPa.

Serpentine coil bundles welded to perforated plates with removable covers for internal cleaning. Available in carbon steel or stainless steel, tested at 860 kPa.

Straight-through design with removable end caps for cleaning. Available in hot-dip galvanized carbon steel or stainless steel, tested at 860 kPa.

Divides coil into multiple independent circuits for varied pressure drops or fluids.

Doubles fluid path length inside coil to increase velocity and enhance heat transfer, suited for low flow rates.

Fan drive expels heat to ambient air. Motors are designed for wet and hot environments with permanently lubricated bearings for maintenance-free operation. BAC’s belt drive system is reliable and easy to maintain.

Uses BALTIDRIVE? belt drive with aluminum pulleys connected by rubber belts for efficient transmission.

Saves energy and reduces noise during partial load operation. Recommended frequency range 25-50 Hz or 30-60 Hz depending on electrical system.

Ideal for large load variations (e.g., day/night). Options include 4/6 and 4/8 pole motors. Consult BAC sales.

Available for hazardous locations. Contact BAC sales.

Two single-speed motors and belts: one at full load, one at two-thirds speed consuming about one-third power. Provides backup with ~70% heat exchange if main motor stops.

Multiple fan types to meet noise requirements.

Low Noise Fan (Optional)
Reduces noise without sacrificing heat exchange.
Ultra-Quiet Fan (Optional)
For more stringent noise limits.
Silencers (Optional)
For inlet/outlet airflow noise reduction.
