2. Advantage of product-:
• Better heat transfer performance-: aluminum heat transfer better than
stainless steel
• Lighter- : Aluminum only 30% weight comparing to copper and brass
• Stronger-: bar-plate structure, turbulators inside, aluminum brazing
• Clean-: all components should be clean when brazing, no flux needed
• Flexible-: products dimension range is very wild. From small cooler to very huge
heat exchanger. Several cooler core can be welded together to enlarge the size
• Cheaper-: no special mould needed for low volume but many modes
