Computer Controlled Crystallization Unit

The Computer Controlled Crystallization Unit, is a cooling crystallization unit. Therefore, it is suitable to perform crystallization experiments with those constituents whose solubility changes according to the temperature.

ATENG 10858 — Computer Controlled Crystallization Unit

(for main items)

• With this unit there are several options and possibilities:
• Main items: 1, 2, 3, 4, 5 and 6.
• Optional items: 7, 8, 9, 10 and 11.
• Let us describe first the main items (1 to 6):
• 1 ATENG 10858. Unit:
  Bench-top unit.
  Anodized aluminum frame and panels made of painted steel.
  Main metallic elements made of stainless steel.
  Diagram in the front panel with distribution of the elements similar
  to the real one.
  Crystallizer composed of jacketed reactor made in glass (1 l of
  capacity), which includes temperature sensors and stirrer. Batch
  operation.
  Double blade variable speed stirrer, computer controlled.
  The crystallization reactor is thermally controlled by means of heated
  water circulating in the reactor jacket. PID control over the reactor
  temperature.
  Thermostatic bath of 600 W, with feed water impulsion pump,
  computer controlled.
• Water flow sensor, range: 0.25 – 6.5 l/min.
  Four two-way valves to allow the water circulation, according to the
  process.
  Four “J” type temperature sensors, located at key points of the system.
• Pressure regulation valve to protect the system, range: 0.5 – 6 bar.
• Conductivity cell to measure the solution conductivity, range: 2000 mS.
• Unit: ATENG 10858
• Set of sieves, composed of:
• Three sieves of different light size: 0.5 mm/ 1 mm/ 2 mm.
• Vessel to collect the crystals, capacity: 2 l.
  Protection devices for the electric circuits.
• The complete unit includes as well:
  Advanced Real-Time SCADA and PID Control.
  Open Control + Multicontrol + Real-Time Control.
  Specialized Control Software based on LabVIEW.
  National Instruments Data Acquisition board (250 KS/s, kilo samples per second).
  Calibration exercises, which are included, teach the user how to calibrate a sensor and the
  importance of checking the accuracy of the sensors before taking measurements.
  Projector and/or electronic whiteboard compatibility allows the unit to be explained and
  demonstrated to an entire class at one time.
  Capable of doing applied research, real industrial simulation, training courses, etc.
  Remote operation and control by the user and remote control for technical support,
  are always included.
  Totally safe, utilizing 4 safety systems (Mechanical, Electrical, Electronic & Software).
  Designed and manufactured under several quality standards.
  Optional ICAI software to create, edit and carry out practical exercises, tests, exams,
  calculations, etc. Apart from monitoring user's knowledge and progress reached.
  This unit has been designed for future expansion and integration. A common expansion is
  the Scada-Net (ESN) System which enables multiple students to simultaneously
  operate many units in a network.
