SS coaxial coils

heat exchanger for marine AC

Marine Condensing Coils

Using sea water as cold source for providing heat/cold air, the marine AC can supply comfortable working can living condition for the marine.


Product Profile:

HZSS Marine condensing coils are made of titanium with enhanced grooveline technology to achieve high efficient and high corrosion resistance.


Product Features:

1. Water in the inner coil and gas in between the innerand outer coil to enhance turbulence intensity  and heat transfercoefficient.

2. Spirally corrugated  tubes increase heattransfer area  to create higher efficiency.

3. Reliable with higher pressure stand and less welding points.

4. Anti-freezing and self cleaning.

5.Titanium inner tube with high corrosion resistance.

6.Enhanced groove line inner tube surface increase heat transferefficient by 30%.
