| Industry | Steel Coating Industry | |
| Fouling Issue / Frequency |
The heat exchanger is installed in a new plant. Based on experiences in the industry, with plate heat exchangers, fouling was expected. There is no data for this plant on fouling and the fouling frequency |
|
| Solution / Approach |
A shell & tube heat exchanger with the self-cleaning configuration to heat up and keep a zinc phosphate bath at a constant temperature. In the zinc phosphate bath steel components are treated with zinc phosphate. The cleaning particles are separated in a gravity separator. |
