Dear Ms Cindy,Thank you for your inquiry. However, we noted that the following information is lacking in the documents that is critical for us to design the air cooler:1. Oil inlet temperature2. Ambient air temperature for cooling3. Any requirements on painting colour and paint thicknessPlease also let us know in the event fortune secures the project, will you be issuing a single PO for all the coolers, or order several units every year from 2020 to 2023? Looking forward to your reply. Thanks and regards,Ng Kian Tiong
