To establish user’s files.

For every sold nitrogen generator / oxygen generator, our company establishes user's files in computer. We collect the content of contract, technical parameters after commissioning, equipment working state, equipment operating state, user’s opinion or suggestion and so on, then we record it in computer so that we can look up easily to serve the user better and improve our work. Therefore help from users would be greatly appreciated. It is better that you send us the record list about equipment operating state and maintenance record by fax or post periodically.
