Microchannel heat exchangers: advantages and benefits

All-aluminium microchannel heat exchanging products are now being widely used in the HVAC industry: they provide higher performance, smaller size, features and capabilities not found in traditional fin/tube heat exchangers.

Microchannel technology offers improved performance by increasing air-side heat transfer between the fins and the ambient air, heat conduction between the fins and tubes and refrigerant-side heat transfer between the tubes and the refrigerant.

Briefly summarized, microchannel heat exchanging technology offer the following improvements over traditional fin/tube designs:

Higher efficiency and performance:

• 20% to 40% greater overall heat transfer performance
• Drastic reduction in airside pressure drops

Smaller size and less weight:

• 10% to 30% smaller coil face upon design conditions
• Thin profile takes up less space
• Up to 60% less weight

Reduced costs:

• Less refrigerant charge
• Reduced material cost

Proven reliability:

• Time-tested manufacturing processes and materials
• Higher corrosion resistance
• More robust construction
