AQUEOUS
The list of advantages and disadvantages listed below covers the water based technology (in no particular order) as follows:
ADVANTAGES LIST (Not in any particular order)
• Cheap initial cost
• Operator risk low
• Filters easy to change
• Cheap chemistry front end
• De-ionised water prevents staining
• Fast cleaning process stages
• Safe process
• Low temperatures in first stages
• Little chemical addition required
• Will remove particulates efficiently
|
DISADVANTAGES LIST
• Large footprint for equipment
• Monitoring critical
• Long process times for drying
• Risk of water retention
• High energy costs
• High CO² levels
• Components will be around 80ºC out of dryer
• Filter changes needed frequently
• High energy input
• Often Impossible to cope with process volumes in the proposed machine
• De ionised water expensive.
• Must have chemical front end
• Four stage process tanks
• Humidity levels in production areas could increase
• Water disposal and usage costs set to escalate due to CO² levels globally
• Water consumption may be restricted in the same way that solvents are already
• More filters to be changed
• More frequent changing of process stages
• Long process times may cause bottle necks in production
• Spray wash systems are not always effective for precision component cleaning
