- Heat exchangers in power plants (nuclear， electric， thermal and geothermal power plants)
- Chemical and petrochemical industries
- Highly corrosive systems (evaporators， condensers…)
- Food processing and refrigeration industries
Advantages of low-finned tubes
- 2.5-3 times the external surface area of bare tubes
- Increased heat exchanger efficiency means fewer tubes are needed to accomplish the same heat transfer as bare tubes
- Low finned tubes can improve the performance of existing exchangers without the difficult and expensive task of building new housings
- Reduced space and weight are valuable for offshore production or high altitude distillation towers. Low fin technology can transform large shell and tube heat exchangers into compact heat exchangers
