Frequently Asked Questions

Quick Answers to Your Technical Questions

Q: What's the difference between inner grooved and smooth copper tubes?
Inner grooved tubes feature internal ridges that increase the heat transfer surface area by 30-50% compared to smooth tubes. This makes them ideal for applications where space is limited and higher efficiency is required, such as in air conditioning evaporators.
Q: How to select the right tubes for flooded evaporators?
Selection depends on refrigerant type, operating pressure, and expected heat transfer rates. Our TE/LE/LF series tubes are specifically designed for flooded evaporator applications, offering enhanced boiling heat transfer performance.
Q: Stainless steel vs copper: Which is better for heat exchange?
Copper offers superior thermal conductivity, while stainless steel provides better corrosion resistance and strength at high temperatures. The choice depends on your specific application requirements and operating conditions.
Q: When should heat exchange tubes be replaced?
Regular inspection is recommended. Signs that tubes need replacement include visible corrosion, reduced heat transfer efficiency, leaks, or mechanical damage. Our technical team can provide professional assessment services.
