Gas lines

  • Standard is a N2 gas line with Mass Flow Controller
  • 3 add. gas lines are possible (inert gases)

Heating

  • Heated by 24 infrared lamps (total power: see pos. 2!) arranged in crossed alignment
  • 3 heating zones 
  • Bottom heating

Vacuum

  • Vacuum capable for external pump system up to 10-3 hPa
  • Vacuum pump is not included and optionally available

Overpressure

  • Maximum overpressure: 2 bar (= 28 psi; absolute pressure: 3000 hPa)
  • Pressure sensor suited for both vacuum (1000 ... 2 hPa absolute) and overpressure (0 ... 2 bar relative)

Process control

  • SPS process controller with 50 programs and up to 50 steps each (Ethernet interface), SIMATIC S7-1200 based
  • Storage of process data in CSV data format on USB 2.0 memory stick, on SD card or to network
  • Including 7" Touch panel for intuitive and comfortable process control in detachable housing

Water cooling

  • Water cooling required (5 bar inlet pressure, 15...20 °C water inlet temperature,
  • demineralised water, free of Cu particles)
  • We recommend either
  • WC-III external water cooler or
  • WC-IV external water cooler or
  • UHE Heat exchanger in case there is a house water supply available
