Up for sale is an incredibly rare, industrial-grade AB Akribi Kemikonsulter Dynamic Drainage Analyzer (DDA) Complete Wet-End Chemistry System. Engineered and manufactured in Sundsvall, Sweden, this professional laboratory analyzer is the global benchmark for simulating and optimizing drainage, retention, and filtration performance in paper mills, cellulose research, and wastewater R&D applications.

This listing features a 100% complete core system setup, including the Physical Filtration/Test Tower assembly, the matching Pneumatic & Electronic Control Unit, and a dedicated laboratory laptop pre-installed with the original, active DDA v3.12 Software interface (as shown running in image_6.png).

Purchasing this complete bundle completely eliminates the immense corporate headache of sourcing separate hardware modules, dealing with missing communication drivers, or tracking down obsolete European software licenses. It is an ideal, plug-and-play core setup for research universities, paper recycling facilities, or chemical laboratories.

📋 Full System Component Breakdown:

1. AB Akribi DDA Physical Filtration & Testing Tower (image_7.png):

   • Sample Cylinder: High-clarity upper acrylic sample vessel for pulp suspension and chemical retention observation.

   • Automated Pneumatic Cylinder: Bottom aluminum heavy-duty piston for automated vessel lifting and positioning.

   • Chemical Dosing Manifold: Upper dual-valve electronic dosing solenoids for automated polymer/additive injections during testing.

   • Vacuum Chamber Assembly: Integrated heavy-duty glass vacuum filtrate container equipped with a built-in top-tier WIKA pressure/vacuum gauge (0 to -1 bar scale) to accurately monitor dynamic dewatering rates. (Features original Cargill R&D asset labeling from a professional research facility).

2. AB Akribi Pneumatic & Electronic Benchtop Control Unit (image_4.png & image_5.png):

   • Front Panel Controls: Manual pressure regulation knobs accompanied by dual high-precision WIKA pressure/vacuum monitoring gauges. Features high-visibility hardware toggle buttons for "Vessel Up" pneumatic lift activation and a "Stirrer Motor Off" safety isolation override.

   • Rear Panel Interfaces: Multi-pin analog/digital interface connections, an integrated cooling fan filtration housing, a standard pneumatic push-to-connect air inlet fitting, and a universal 90-254VAC power module.

3. Dedicated System Laptop w/ Pre-Loaded DDA v3.12 Software (image_6.png):

   • Boots directly into the proprietary DDA v3.12 Settings panel.

   • Allows the operator to save, configure, and modify critical testing matrices, including: Preparation Time (s), Stirrer Lift Time (s), Dry Solids (g/l), Amount Furnish (ml), Target Vacuum parameters (mBar), max exposure times, and custom directory routing for .DDP output files (C:\DDAresults\).

• System Condition: Used industrial laboratory surplus.

• Operational Status: Outstanding mechanical and electrical core condition. The control unit powers on perfectly (green power LED illuminates). The laptop boots up smoothly and runs the active DDA v3.12 interface without errors. The structural valves, fittings, and WIKA gauges on the tower are in excellent condition. Full chemical-run loops are untestable due to lack of facilities. System is sold As-Is / Untested for full chemical cycles.

• Cosmetic Condition: Very clean, professional laboratory condition. Minor superficial scuffs on the benchtop casings from standard R&D operations.

• Included Items: AB Akribi DDA Filtration Tower, AB Akribi Pneumatic/Electronic Control Unit, Dedicated System Laptop with DDA v3.12 software, and power supplies/cables. (Ships securely inside the heavy-duty aluminum flight/travel case shown in the pictures)
