听力每日练习 listen 2798 A new installation

1--Would you like me to show you our new cleaning unit? It's a clever design.
 
2-- Yes, I'd like to see that. What does it clean exactly?
 
1-- It washes the solvent off all the metal parts - the blades, trays etc. - and then sends it back into the system.
 
2--What does the unit consist of?
 
1--Well, it’s basically two tanks – one for the dirty solvent and one for the clean solvent a pump and a washing unit. Oh, and there’s a cooling system and a filter. It‘s all controlled by a PLC system – that stands for Process Logic Control.
