In many industrial processes, scrubber performance depends heavily on stable and controlled inlet gas temperature. Hot process air can reduce scrubbing efficiency, increase chemical consumption, and accelerate corrosion inside the scrubber. To solve this challenge, a custom-designed stainless steel finned tube air cooler is installed upstream to cool the process air before it enters the scrubbing unit.
This custom air cooler is engineered specifically for applications requiring high corrosion resistance, low pressure drop, and reliable thermal performance—even when operating near atmospheric pressure and with traces of H₂S in the gas stream.
Key Mechanical Features
1. Stainless Steel Construction
Tubes, fins, headers: SS304 or SS316
Casing & supports: stainless steel
Fasteners, flanges, and drain components: stainless steel
2. 30-Inch ANSI Pattern Flanged Connections
Designed for simple alignment with existing ductwork.
3. Finned Tube Coil Block
Multi-row, multi-pass configuration
High-efficiency fin design
Optimized for gas-phase cooling
Suitable for high humidity (75–90% RH)
4. Internal Flow Optimization
Uniform gas distribution across the coil face
Smooth inlet and outlet transitions
Integrated drainage for condensate
Optional mist eliminators if required
Thermal Performance Advantages
The cooler is engineered to reduce process air temperature from 130 °C to 40 °C, ensuring the downstream scrubber operates within its optimal range:
Improved absorption efficiency
Stable chemical dosing
Reduced scaling or corrosion inside the scrubber
Longer packing and media life
Improved environmental compliance
The finned-tube configuration, combined with the ambient air temperature at 1,500 m elevation, allows accurate thermal design without oversizing or excessive fan power.
