CDU 1500


Circulating Chemical Delivery Unit

The MABAT CDU-1500 types are offering a circulated chemical loop between the unit and the plating tool. The systems' are allows internal batches preparation and circulating the chemical while controlling the required parameters of temperature and pH levels.

The system is build as two identical, independent units in one cabinet to support two chemicals supplies to the plating process. The unit can be delivering in one cabinet, half size, to support one main chemical batch only.

Only the highest quality components are used in its construction and the module controller utilises the very latest control technology.

The CDU can be interlinked with existing factory monitoring systems, please consult with MABAT’s software engineering dept.

  • Handles most aqueous chemicals
  • Small footprint
  • 3 sides maintenance access
  • Utilities located at high level for easy connection
  • Circulating the batch from ant to the tool (gravitationally)
  • High volume batch size of up to 450 Liters
  • Automatic pH level correction according to operator set point 
  • Polypropylene cabinets with height adjusting feet mounted on a stainless steel chassis
  • High Level resolution touch screen for local operation
  • All chemical handling pathways, tubing, valves and pumps utilise HP440/HP450 PFA & PTFE
  • Pneumatic actuation of valves, transfer and delivery chemical pumps
  • Pumped drain from the cabinet base which acts as leak containment
