I am looking for an article on Tempered Water System. Any references will be appreciated.

To process1, you simply enter tempered water systems and the internet will provide you with plenty of information.

I don't have any article about tempered water systems, but work extensively with one and designing another at my previous employer. The process cooled / condensed heavy hydrocarbons that would freeze below 120oF. Since this could happen with cooling tower water, a tempered water loop was used which supplied water at 140 oF for process cooling. The water was cooled with an air cooler, but I think a plate-frame exchanger with cooling water would be more economical depending on available utilities.

Any specific issues on tempered water?

Another usual recommendation is to use parallel-flow exchangers to ensure there is no temperature cross-over with possible sodification of the warm stream.
