Auto Parts Test Equipment Double System Automobile Refrigerant Vacuum Filling Machine
Application:
It can be used for filling the refrigerant (R22, R134a or R410a).
Working process:
After the filling gun is connected to the workpiece, press the start switch, and the filling machine will automatically vacuum the workpiece. When the workpiece reaches the set vacuum, the equipment will perform vacuum pressure-holding and leak detection on the workpiece; if the workpiece is found to be leaking, the equipment will automatically stop the charging procedure and alarm; if it is confirmed that the workpiece is not leaking, the equipment will automatically open the charging valve to fill the workpiece. When the charged refrigerant volume reaches the set value, the system will automatically close the charging valve. The filling completion signal lights up and the filling process is complete.
