• Control range: 5 ºC – 35 ºC.
• Cold water recycling pump:
• Maximum flow: 80 l./min.
• Maximum height:
• Water tank. Capacity: 55 l.
• Climatic chamber suitable for people: Unit: ATENG 12719
• Dimensions: 1125 x 1125 x 2100 mm.
  Muffler installed at the air inlet of the climatic chamber.
• Insulation: 60 mm.
• Instrumentation:
  Twelve temperature sensors that make up six hygrometers (five strategically located along the tunnel
• and one located in the climatic chamber):
  Six “J” type temperature sensors (dry bulb).
  Six “J” type temperature sensors (wet bulb).
  Two “J” type temperature sensors to measure the cold water temperature at the inlet and outlet of the
  heat exchanger.
  “J” type temperature sensor to measure the water temperature before entering the water chiller.
• Two air flow sensors, range: 0 – 300 l/s.
• Six humidity sensors, range: 0 – 100 %.
  Three wattmeters to measure the power consumption of the heating element, water chiller and
  humidifier.
  Psychrometric chart.
• The Data Acquisition and Control Software of the ATENG 12719 unit allows:
  Real time representation of all measured magnitudes. Recording of testing measurements in function
  of time and generation of a file compatible with spreadsheet applications.
  Real time representation in the psychrometric chart of the humidity values obtained.
  Manual operation of the system, controlling every stage and setting stable conditions in each one, or
  an automatic operation, setting comfort conditions in the climatic chamber.
• 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, as well as remote support from 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.
