Due to hard coat machine have a problem. Dehumidifier system can not work, we found high percentage of room humidity (65-75%RH, 25˚C) as it’s can not control within hard coat technical standard. So technical side would like to request you to connect new chiller for hard coat machine in order to improve and control humidity & temperature within (20-40%RH, 20˚C).Could you please support us for this requested? If you have a question or problem, Please don’t hesitate to let me know.
