About this file
This is a Baltimore Aircoil Company Cooling Tower Selection Report for a PCT0505-P3-I cooling tower model, designed for a project in Australia dated August 26, 2024. The single cooling tower unit has a flow rate of 19.81 l/s, a standard fan motor of 3.73 kW, and is capable of heat rejection at 460 kW. Key engineering specifications include a unit length of 1.67 m, width of 1.67 m, height of 2.90 m, air flow of 29,988 m³/h, and an approximate operating weight of 1,325 kg. The tower requires a minimum distance of 0.9 m from a solid wall and 1 m from a 50% open wall, with an energy rating of 52.80 USGPM/HP per ASHRAE standards. Sound pressure levels are detailed across various octave bands, with measurements taken at 1.5 m and 15 m distances, and a total sound power level of 94 dB(A).
