Vacuum plays a crucial role in various manufacturing processes in which products have to be filled with gases or liquids. Examples include refrigerant circuits for heat pumps, air conditioning systems and refrigerators, brake lines in vehicles, heat pipes and gas-filled lights.
Areas of application:
- Refrigerators, heat pumps and air conditioning systems
- Filling hydraulic vehicle brakes
- Filling gas cylinders
- Heat pipe production
- Lighting production
Before finally filling a product with gas or liquid, it is crucial to evacuate the interior to create a clean and dry environment and ensure “bubble-free” filling.
The challenges in filling applications are manifold. In addition to removing air, moisture or even droplets of liquid often need to be pumped out of the volume.
