BAC S15E 1018-10 LE

BAC S1500E Cooling Tower

The BAC S15E 1018-10-LE is a high-performance, open-circuit cooling tower from the S1500E series manufactured by Baltimore Aircoil Company (BAC).
This specific model is designed for industrial cooling applications and large HVAC systems where high efficiency and ease of maintenance are priorities.

Technology

Patented BACross III fill media system, which allows for easy inspection of the fill to prevent biological growth (e.g., Legionella).

Key Features of the S1500E Series

Maintenance access: A large, inward-swinging access door and internal maintenance platforms allow technicians to conveniently perform inspections while standing inside the unit.
Hygiene control: The design minimizes standing water and protects against sunlight through special air inlet elements, reducing algae growth.
Flexibility: The single-sided air intake allows the cooling tower to be installed even in confined spaces or directly against walls.
Materials: Galvanized steel with Baltibond hybrid coating.

Typical Applications

Industrial cooling: Used in factories for process cooling.
HVAC: Used in large building complexes as part of a central chiller system.
Refrigeration: Used as a condenser in commercial refrigeration systems.

Cooling Capacity

An open evaporative cooling tower does not have a fixed, single kW cooling capacity, as the actual performance depends entirely on the thermodynamic ambient conditions and system temperatures.

The model is designed for maximum flow rates of up to 198 liters per second.

Under typical industrial or HVAC standard conditions, the nominal cooling capacity of this model is in the range of approximately 1,200 kW to 2,100 kW.

Why does the cooling capacity vary?

Wet-bulb temperature (outside air): The cooler and drier the ambient air, the more water can evaporate, and the higher the cooling capacity.

Water temperatures: The performance changes significantly depending on the warm water inlet temperature (e.g., 35 °C) and the cold water outlet temperature (e.g., 29 °C).

Air volume flow: According to BAC's technical data, the S15E 1018-10 LE model actively moves 60.0 m³/s of air through three installed 11.0 kW fan motors.

If this air volume is reduced by a frequency inverter (e.g., during night operation or in winter), the cooling capacity decreases in a controlled manner.

Approach: This is the most important thermodynamic limit. It describes the difference between the desired cold water temperature and the physically determined wet-bulb temperature. The closer the cold water is cooled to the wet-bulb temperature (smaller approach), the less kW of power the tower can provide.
