Aftercooler Manufacturer in India

What is an Aftercooler?

An aftercooler is a heat exchanger that cools compressed air immediately after it exits an air compressor, reducing its temperature by 50-200°F (30-110°C). This process:

• Condenses moisture from the air
• Protects downstream equipment
• Improves system efficiency

Key Differences: Aftercooler vs. Intercooler

Feature	Aftercooler	Intercooler
Location	After the final compressor stage	Between compressor stages
Primary Function	Final air cooling before use	Intermediate cooling between stages
Typical Temp Drop	110-200°F (60-110°C)	50-150°F (30-80°C)
Common Applications	Industrial air systems	Turbocharged engines

Types of Aftercoolers

1. Air-Cooled Aftercoolers

• How it Works: Uses ambient air to cool compressed air via finned tubes
• Best For:
  • Small to medium compressors (5-200 HP)
  • Outdoor installations
• Advantages:
  • No water required
  • Low maintenance
• Disadvantages:
  • Less effective in hot environments

2. Water-Cooled Aftercoolers

• How it Works: Uses circulating water to cool compressed air

• Best For:
  • Large industrial compressors (200+ HP)
  • High ambient temperature areas
• Advantages:
  • More consistent cooling
  • Compact design
• Disadvantages:
  • Requires water supply
  • Higher maintenance

3. Refrigerated Aftercoolers

• How it Works: Uses refrigeration cycle for precise temperature control
• Best For:
  • Critical applications needing exact air temps
  • Medical/pharmaceutical uses
• Advantages:
  • Most effective cooling
  • Can reach dew points below ambient
• Disadvantages:
  • Highest energy consumption
  • Complex installation

Why Your Compressed Air System Needs an Aftercooler

1. Moisture Removal – Condenses 60-80% of water vapor
2. Equipment Protection – Prevents damage to:
   1. Air dryers
   1. Pneumatic tools
   1. Piping systems
3. Energy Savings – Cooler air is denser, requiring less energy to compress

1. Improved Air Quality – Reduces contamination in sensitive processes

Aftercooler Efficiency Factors

Factor	Effect on Performance
Cooling Medium Temp	Lower = better cooling
Air Flow Rate	Must match compressor output
Surface Area	More area = better heat transfer
Fouling	Dirty fins reduce efficiency

Maintenance Requirements

• Daily: Check for proper operation
• Weekly: Inspect for leaks
• Monthly: Clean fins/tubes
• Annually: Replace worn components

Pro Tip: Install an automatic drain to remove condensed water!
