Dear Khun Pattaraporn,
Sorry for any inconvenience.
We have discussed this matter and have solve this problems by
1. We will extend the warrantee from 12 months after commissioning, 18 months after delivery at site whichever comes first to 24 months after delivery.
2. Or, we will bring Thermowell back to our warehouse tomorrow if possible. Then we will re-produce the items with the origin as your request. Please note that we can deliver all items back to your site around 20 Jan 15 because of the long holiday.
