求翻译：I like the idea of retrieving the nitrogen. It would be good to use the retrieved nitrogen for the oil tempers. In the specification for the tempers I asked for the same controller that Lebanon uses, the HC900 with the companion HMI. The .pdf for the controller is attached. Please ask the supplier if they can use this instrument/PLC/HMI. This is a very powerful controller for such a small asset. It would be good to use the same device on different pieces of equipment so the Operator does not need to learn so many different controllers. Also the people that come from Lebanon use this controller for the oil temper furnaces there so they know the controllers very well and can use them and train you on how to use it. It will add some cost compared to what supplier already offer.是什么意思？
