Answer: Water-cooled dryers are often in the same room with other water-cooled equipment (such as air compressors). When piping the cooling water, the dryer should have an independent drainage outlet. If the drainage pipe is shared with other water-cooled equipment, the return water may be blocked due to different water pressures. If you must share a drainage pipe, you should try to use a straight-angle connection and avoid T-connections or reverse-angle connections.
