Advantages
Cost saving due to consumption of chemicals being reduced by approx. 30 %
No rinse water, no overflow water
No water treatment, no chrome reduction or decontamination
No chromic hydroxide sludges to be discharged to special dumps
Avoidance of aerosols and vapours containing chromate; hence no damage to health
Reduced expenses of staff, industrial instrumentation and of measuring instruments for operator’s control and maintenance
Optimal adaptation of coat thickness and its homogeneity within the micron range
Increase in strip surface throughput rates to a maximum of 460 m2/min at strip speeds of 200 m/min
Reduction in installation space and in drying times by abt 50 % as compared to conventional processes
No strip heating required, because the processing temperature of abt 50°C is already attained in the preceding cleaning stage

Special Features
Stainless steel rolls, highly resistant to corrosion; hence long lifetime
Motorized fine adjustments of the rolls, enabling precise positioning (abt 1 micron); hence reproducible coat thicknesses
Linear position sensors for reproducible setting of stored reference values even if the product is changed
Frequency controlled roll drives for optimum adaptation of the roll peripheral velocity to the line speed
Passline roll used to keep the strip flat for two-side coating
Mobile coater heads to facilitate roll and vat removal, cleaning and maintenance work, and presetting of specific production parameters.
