7.20.2. Cooling water for Carbon container
(optional)
A cooling water bypass provides additional cooling for the carbon without requiring
additional cooling water.
Every time the cooling water for the machine (i.e. distillation, cooling unit, liquid circulation cooler)
flows, the cooling water flows via the bypass (valve NO) through the heat exchanger in the carbon
container cooling the carbon nearly during the entire operation process. Even after several
adsorptions, the carbon will still remain permeable.
The bypass is closed during two process functions:
- Adsorbing to be expected – heating of carbon
- Adsorbing to be expected – cooling phase 1 (all the cooling water needed for the cooling unit)
