How to produce CROSS FIN TUBE heat exchanger
The tube material of STS FIN TUBE heat exchanger manufactured by Joongwon Refrigeration & Heating can be selected from STS 304, STS316L, and it has a diameter of12.70M/M and a thickness of 0.7M/M. Heater and distributors, branches, U band, and capillaries are also made of STAINLESS STEEL. The efficiency of STS CROSS FIN TUBE is about 50% of a copper tube - aluminum FIN coil.

Areas that utilize the excellent corrosion resistance of STS Coil
1. Heat recovery industry
- Use of exhaust heat (substitute carbon steel pipe for pressure piping sensitive to low-temperature corrosion)
- Industries where white lead is a problem
- The miniaturized heat recovery system of high efficiency in micro-turbine facility system
2. Industry related to edibility
- Heat exchanger required cleaning used in HACCP facility
