Drying After Aqueous Parts Cleaning
An environmentally sound way of drying components to very high standards.
Download this white paper to understand key requirements and considerations when defining your drying cleaning equipment needs for your industrial machining process. This will help ensure you get the cleaning results you need based on your quality requirements.
The level of dryness required varies from simply removing excess water to prevent spills and maintain a clean, safe work environment, to drying for critical processes such as thermal deburring, leak testing, and assembly.
Drying is accomplished primarily by evaporation and physical displacement. Evaporation rate is dependant on the difference in vapor pressure between the water on the part and the air used for drying.
Where washing temperature is high (140°F or greater), parts will dry in ambient air within minutes of exiting the washer and no extra drying system is required:
- High-impact air blow-offs
- Recirculating (low impact) blow-offs
- Compressed air blow-offs
- Vacuum dryers
- Convection ovens
In applications requiring tight cleanliness standards it is important that the drying system be designed to prevent recontamination of a precision-cleaned workpiece. Blower suction filters and stainless-steel construction for piping, air knives, and nozzles are required to ensure that that only clean air contacts the workpiece.
