Product Description
The Antifreeze Vacuum Filling Machine uses a PLC-controlled system to automate the complete coolant filling process. The system first performs vacuum evacuation, followed by leak testing under vacuum and pressure conditions. After confirming system tightness, a secondary vacuum is created before the coolant is introduced under controlled pressure.
Once the filling pressure reaches equilibrium, the system automatically vents to atmospheric pressure and performs back suction to remove excess coolant. This helps achieve the specified liquid level and prevents the coolant level from dropping after filling.
The complete cycle integrates vacuum evacuation, leak testing, pressure filling and back suction, making the machine suitable for automated coolant and antifreeze filling applications on automotive production and assembly lines.
