BAC S1500E

BAC S1500E Cooling Tower
The BAC S15E 1018-10-LE is a high-performance open cooling tower from the S1500E series 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 paramount.

Technology
Patented BACross III fill pack system allows simple inspection of the fill sheets to prevent biological growth (e.g. Legionella).

Key Features of the S1500E Series
- Maintenance Access: Large, inward-swinging access door and internal maintenance platforms enable technicians to perform inspections comfortably while standing inside the unit.
- Hygiene Control: The design minimizes stagnant water and protects against sunlight using special air intake components, reducing algae growth.
- Flexibility: The single-side air intake allows the tower to be installed in confined spaces or directly against walls.
- Materials: Galvanized steel with Baltibond hybrid coating.

Typical Applications
- Industrial Cooling: Used in factories for process cooling.
- Air Conditioning (HVAC): Integrated in large building complexes as part of central cooling systems.
- Refrigeration Technology: Used as a condenser in commercial refrigeration circuits.

Cooling Performance
An open evaporative cooling tower does not have a fixed kW rating, as the actual capacity depends entirely on thermodynamic ambient conditions and system temperatures.
This 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 ranges from approximately 1,200 kW to 2,100 kW.

Why does cooling capacity vary?
- Wet bulb temperature (ambient air): The cooler and drier the air, the more water can evaporate and the greater the cooling effect.
- Water temperatures: The performance changes significantly depending on the entering hot water temperature (e.g., 35°C) and the exiting cold water temperature (e.g., 29°C).
- Airflow volume: The S15E 1018-10 LE model, according to BAC's technical data, actively moves 60.0 m³/s of air using three 11.0 kW fan motors.
- If the airflow is reduced via frequency inverter (e.g., during night operation or in winter), the cooling capacity is deliberately reduced.
- Approach: This is the main thermodynamic limit. It describes the difference between the desired cold water temperature and the physical wet bulb temperature. The closer the cold water is cooled to the wet bulb temperature (smaller approach), the lower the tower's cooling capacity in kW.
