How It Works
Working Principle
Dry coolers reject heat entirely through sensible air-side heat transfer -- no evaporation, no water consumption.
Schematic: Air-side sensible heat rejection -- no water contact with process fluid
Hot Fluid Enters the Coil
Process fluid (water, glycol solution or other heat transfer fluid) at elevated temperature enters the dry cooler coil circuit through the inlet manifold.
Fans Draw Ambient Air Across Coil
Axial fans force or draw ambient air across the finned coil surface. The large fin surface area maximizes contact between the hot fluid tubes and the cooler air stream.
Sensible Heat Transfer
Heat transfers from the fluid through the tube wall and aluminum fins to the air by convection. No evaporation occurs -- the process is entirely dry. Achievable outlet temperature is limited by ambient dry-bulb temperature.
Cooled Fluid Returns to Process
The cooled fluid exits through the outlet manifold and returns to the process equipment -- compressor, chiller, hydraulic system or production machinery -- completing the closed loop.
Key Engineering Note: Minimum achievable outlet temperature = ambient dry-bulb temperature + approach temperature (typically 5-10°C). Accurate site dry-bulb data is essential for correct equipment selection.
