Introduction
Air-Cooled Heat Exchangers (ACHE) are critical heat transfer devices that reject heat from process fluids to the ambient air without the need for water. These exchangers are ideal for industries where water is scarce or expensive, providing energy-efficient, environmentally friendly, and low-maintenance cooling solutions.
At NORDSTONE., we specialize in custom-engineered ACHE systems, designed to operate under extreme temperatures, high pressures, and continuous industrial loads, serving industries such as petrochemical, oil & gas, power plants, chemical, HVAC, and refinery applications.
What are Air-Cooled Heat Exchangers?
Air-Cooled Heat Exchangers are thermal management devices that use atmospheric air as the cooling medium to remove heat from process fluids. They consist of finned tubes through which hot fluid flows, while fans or natural draft move air across the tubes to facilitate heat transfer. These systems eliminate water consumption and associated treatment costs.
Key components include:
- Finned tube bundles for enhanced heat transfer
- Axial or centrifugal fans for forced air movement
- Steel structure and supports
- Inlet and outlet headers
- Plenums and air ducts
- Drive systems (motors, belts, couplings)
- Control systems and instrumentation
Our ACHE systems are engineered for optimal thermal efficiency, reliability, and minimal maintenance in demanding industrial environments.
