Process thermostats Integral XT

With their high heating, cooling and pump capacities, LAUDA Integral XT process thermostats create a new thermostating dimension in process engineering. The basic principle comprises a circulation thermostat with a very small internal volume and anon-perfused expansion vessel.

Process thermostats Integral T

Integral T are extremely efficient process thermostat in a compact design. As generalists for fast, precise thermostating in the external circuit, they easily master the most demanding tasks.

  • Programmer with max. 150 temperature/time segments
  • Parallel display of 2 temperature values with a resolution of 0.1 °C
  • Discharge pressure display
  • External control via Pt 100 temperature probe or standard signal
  • User calibration and LAUDA 2-point calibration
  • Analogue inputs (3) and outputs (2), e.g. for control system. Can be configured to 0 to 10 V or 0/4 to 20 mA
  • Malfunction indication for low level, overtemperature, pumps and cooling compressor
  • Remote "malfunction" display via neutral contact
  • Stand-by switch via neutral contact
