Fully automatic state of the art XL batch cleaner for assembled PCBs

The kolb AQUBE® series offer next-generation cleaning systems - even more efficient, even more compact, easy to handle and maintain, pre-equipped for extended water management and ready for the smart factory (SF ready certified).

AQUBE® LH7 is a fully automatic XL high volume new generation PCB fine cleaning system - except AQUBE® 9 types there are no PCB cleaning batch systems with a comparably large chamber size available worldwide - with a capacity of up to 540 (8.6 m² / 92.5 ft²) eurocards and a relative cleaning time of 10 seconds per card.

AQUBE® LH7 is a German engineered and manufactured machine primarily for the process safe fine cleaning of assembled PCBs, hybrids (HDIs, SiPs) and misprints from reflow flux residues, resin, copper, oxide and soldering support substances.

The two-tank, triple-circuit function configuration with ClosedLoop water reprocessing ensures short cycle times and makes this system the perfect economic choice for the precision cleaning of assembled PCBs.



  • Two tank system with triple circuit function
  • Smart Factory ready: DNAccess, remote control, traceability (PLC data scanning and memorizing)
  • Fully automatic 4step process: cleaning, rinsing (tap water), DI-water rinsing, VMH®-TurboDigital hot air evaporative drying
  • 10 seconds relative cycle time for the cleaning, rinsing and drying one eurocard
  • Horizontal PTFE mounted rotor system with up to eight asynchronous spray rotors for thorough wetting (no blind spots)
  • Heater cleaning tank A, automatic water change for the rinsing circuit, DI water system, mixing-blending unit, water measuring unit (ion contamination measurement), ion exchanger and fine filter system as standard
  • Processes and service intervals PLC controlled. Event issuing and software control via touch screen
  • EDGELESS Design and VARIccess® service access: maximum capacity, easy maintenance on a very small footprint
  • Suitable for high temperature cleaning and rinsing up to 80 °C (176 °F)
