Answer: The heat transfer effect of water-cooled dryers is better than that of air-cooled dryers, but they consume more water and have the following requirements for water quality:
(1) The water temperature entering the dryer should be below, and the outlet water temperature should not exceed.
(2) The water pressure should be maintained above 0.15MPa to ensure smooth water flow (but
it should not be too high, refer to the machine nameplate regulations).
(3) The magnesium and calcium ions in the water should not be higher than the general standard of neutral soft water.
(4) There should be no solid debris visible to the naked eye in the water.
