Finned Tube Heat Exchanger

Our independently developed Air Separation Compressor Intercooler and Aftercooler adopts innovative surface contact low thermal resistance technology and optimized finned tube shell structure, perfectly solving the industry’s common technical bottlenecks, and providing high-stability, energy-saving and space-saving cooling solutions for medium and large air separation units in Middle East and European industrial scenarios.

1.Performance: Self-developed curved vortex generator combined with anti-clogging turbulence fins increases heat transfer efficiency by 10.9%, delivering precise temperature control, energy savings, and fouling resistance.
2.Structure: Expanded-and-welded joint for media isolation, with curved turbulence design tailored to operating conditions.
3.Reliability: Customizable helium leak detection, dedicated natural frequency inspection, hydrostatic pressure testing, and non-destructive examination (NDE).
4.Maintainability: Modular pull-out design allows servicing without disassembling the main generator, reducing downtime and associated revenue loss.

1.Superior resistance to seawater and treated water corrosion.
2.Higher yield strength at elevated temperatures compared to mild steel.
3.Verified weld integrity reduces the risk of catastrophic failure.
4.Adopting a professional finned tube enhanced heat exchange structure, this unit delivers 343㎡ total heat exchange . The multi-dimensional expanded contact area enables full-coverage medium heat exchange and greatly boosts waste heat recovery efficiency. For continuously operating industrial plants, it delivers superior annual energy savings and better energy-saving performance than conventional equipment.

This cooler series is exclusively optimized for compressor post-compression high-temperature gas cooling.
The premium shell-and-tube structure features smooth internal flow channels that resist dirt accumulation and scale deposition, maintaining stable long-term heat exchange efficiency. Reliable pressure drop control eliminates system faults caused by parameter deviations, reduces mandatory shutdown maintenance frequency, and cuts long-term operational and maintenance costs.
It delivers outstanding operational stability and comprehensive cost performance for large-scale, long-cycle industrial production scenarios.
