In a CAT 3516 DITA JWAC system, the air-cooled heat exchanger transfers heat from the hot jacket water to ambient air. The system typically consists of:
Finned tube heat exchanger core
Axial or centrifugal fans
Structural frame and mounting base
Inlet and outlet headers compatible with CAT JWAC piping
Hot jacket water flows through the tubes, while ambient air is forced across the finned surface, dissipating heat without the need for cooling towers or large water consumption.
To meet the thermal and mechanical demands of CAT 3516 DITA engines, JWAC air-cooled heat exchangers are typically designed with:
Elliptical or round tubes to optimize air-side pressure drop
Aluminum or steel fins for efficient heat transfer
Carbon steel or stainless steel headers for durability
High-efficiency axial fans matched to required heat rejection
Vibration-resistant tube supports for engine-driven environments
Design parameters are tailored to:
JWAC flow rate
Inlet and outlet temperature requirements
Ambient design temperature
Site altitude and noise limitations
Because CAT 3516 DITA installations vary widely by application and environment, air-cooled JWAC heat exchangers are often custom-engineered, including:
Thermal design verification to CAT specifications
Customized nozzle sizes and orientations
Anti-corrosion coatings for marine or coastal environments
Low-noise fan solutions for urban or sensitive areas
OEM and ODM services ensure full compatibility with CAT engine performance requirements.
Air-cooled heat exchangers provide a robust, efficient, and water-free cooling solution for CAT 3516 DITA JWAC systems. With proven reliability, flexible installation options, and low lifecycle costs, they are an optimal choice for demanding industrial and power generation applications where performance and durability are critical.
