Condition: used, 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 Ledpfxsynkbms Ab Aehn 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. Technical Data: Fan and Air Data - Air volume flow: 60.0 m³/s (generated in suction operation) - Fan motors: 3x 11.0 kW (axial fans) - Technology: Integrated belt drive - Water flow: 198 l/s Hydraulic Connections - Water inlet: 1x DN 250 (nominal size ND 250 mm) - Water outlet: 1x DN 300 (nominal size ND 300 mm) - Make-up water connection: 1x DN 40 (ND 40 mm) - Overflow / Drain: DN 80 (ND 80 mm) / DN 50 (ND 50 mm) Dimensions and Weights - Operating weight: 11,446 kg (including water fill up to overflow) - Shipping weight: 5,350 kg (empty weight) - Heaviest single part: 3,114 kg (for installation)

This type of system is designed to power low-temperature installations – freezers, freezing tunnels, and advanced refrigeration systems in food processing plants (meat, fish, bakery). The design based on three identical units allows for very flexible, three-stage cooling capacity management (in steps of 33%). The system automatically activates the appropriate number of compressors depending on the actual thermal load, which optimizes energy consumption and extends the service life of the components. The entire unit is mounted on a compact support frame, which facilitates installation. Key features: - Reliable Bitzer two-stage compressors: The two-stage compressor series is specifically designed for deep freezing. It ensures stable operation at very low evaporation temperatures and is characterized by a high energy efficiency ratio. - Safety and automation of the Linde frame: The industrial design of the frame integrates a common suction and discharge manifold, an advanced oil equalization and separation system, and the necessary control and measuring equipment (protective pressure switches), which effectively protects the system from failures. - Industrial protection class (IP 54): Hermetic electrical boxes and the compressor design protect the system from moisture and dust, allowing for safe operation in harsh machine room conditions. - Application versatility: The unit is factory-designed to operate with R22 refrigerant. Due to the presence of compressors with the "Y" designation (filled with ester oil), the system can be successfully adapted to work with modern, environmentally friendly alternatives from the HFC group (e.g., R448A / R449A / R404A / R507) after a standard verification of seals and automation settings.
