Copper tubes for refrigeration circuits

Copper tubes in which a refrigerant circulates are installed in refrigeration circuits. This is filled via a filling valve. After the filling process, the tube is cut off from the ultrasonic welding machine by the filling valve in a single operation and at the same time welded gas-tight so that the refrigeration circuit is hermetically sealed. This application is also possible with aluminium tubes.
