Vapour Degreasing – High-Performance Precision Cleaning

Effective Solvent Cleaning for Industrial Components

Vapour degreasing is a highly effective industrial cleaning process used to remove oils, greases, waxes, flux residues and other contaminants from precision-engineered components.Using heated solvent vapour, the process delivers thorough, consistent cleaning, even on complex geometries and difficult-to-reach surfaces. As the vapour condenses onto cooler components, it dissolves contamination before evaporating to leave parts clean, dry and free from solvent residues, often without additional rinsing or drying. Widely used in aerospace, automotive, medical device manufacturing, electronics and precision engineering, vapour degreasing provides a reliable solution for demanding component cleanliness requirements.

How Does Vapour Degreasing Work?

The process typically involves three key stages:

1. Solvent Immersion: Components are immersed in heated solvent to dissolve and remove stubborn oils, greases and manufacturing residues.

2. Vapour Cleaning and Rinsing: Clean solvent vapour condenses onto cooler components, removing remaining contamination and providing a final rinse.

3. Drying: As components warm, condensation stops and residual solvent evaporates, leaving parts clean and dry, ready for further processing.

Enhanced Cleaning with Ultrasonic Technology

Modern vapour degreasing systems can incorporate ultrasonic cleaning to improve the removal of stubborn contaminants from intricate components, blind holes and narrow passages.

Combining ultrasonic cleaning with vapour rinsing and drying provides an efficient, repeatable process for high-precision manufacturing applications.

Solvent Cleaning Equipment

D&S Ultra-Clean Ltd supplies advanced solvent cleaning systems for applications requiring consistent, high-quality results across sectors including aerospace, medical, electronics and precision engineering.

Closed solvent cleaning equipment (Types III–V)

Closed solvent cleaning systems carry out cleaning, rinsing and drying within a sealed chamber, helping to minimise operator exposure and reduce solvent emissions. These systems are designed to prevent solvent vapours from escaping into the workplace, improving air quality and reducing potential health and safety risks. Many incorporate automated cleaning cycles, vapour recovery and solvent recycling features, which improve efficiency, reduce solvent consumption and limit environmental impact.

Enclosed solvent cleaning equipment (Types II–III)

Enclosed solvent cleaning systems are designed to contain solvents and their vapours throughout the cleaning process, helping to minimise operator exposure and reduce emissions into the workplace. These systems are particularly suited to precision cleaning applications where high levels of cleanliness, consistency and process control are required. By providing a controlled cleaning environment, they help ensure reliable cleaning performance while improving workplace safety, reducing solvent losses and supporting compliance with environmental regulations.
