BasicLINE: Painting systems: Steam technology

The system essentially consists of a steam generator, a material supply and the DA3 spray gun.

The steam generator is available in different configurations. Water softening is necessary if feedwater of suitable quality is not available. Fully automatic blowdown minimises the maintenance effort.
A pump or pressure vessel is conventionally used to supply the material.

BENEFITS

Gentle application – lower material consumption
The material is atomised by the steam as it leaves the nozzle. The physical properties of superheated steam ensure a uniform, gentle coating with very little rebound. Extremely high transfer efficiency can be achieved, resulting in minimal overspray.

Higher gloss
The particularly fine atomisation produces a higher gloss level.

Significant reduction in total air requirements
The steam spraying process replaces conventional spray air generated by compressors with gentle steam. Compressed air is only used to convey the spray material via a pump or pressure vessel.

Shorter drying and processing times
The steam spraying process significantly reduces drying times through fine atomisation and lower residual moisture. This reduces waiting times before drying or firing and minimises the space required.

Improved working conditions
Lower spray pressure reduces noise exposure. Less paint mist also reduces the burden on the operator and the cleaning and maintenance effort.
