1. Marine air conditioner: Because of high corrosion resistance, it resisted the corrosion by salinity in sea water, prolonged lifetime as well as reduced maintain cost, and a compacted size with high heat exchanging capacity

2. Ice maker: Ice maker and ice-cream machine worked under low temperature. They need salty water. Nominal heat exchanger is easy to be corroded to be leaked. But cupronickel has high corrosion to prohibit leaking.

3. Sea water sourced heat pump

4. Waste water sourced heat pump
