LAUDA Integral XT

Extremely broad temperature range and rapid temperature changes:

Integral XT

LAUDA Integral XT process thermostats allow extremely rapid temperature changes, resulting from the small, internal, thermally active heat transfer medium. The instruments work according to the highly efficient flow principle with a broad working temperature range. The process thermostats are used where rapid temperature changes or high refrigeration and heating performance are required.

Application examples

  • Temperature control of stirrer tanks
  • Temperature control of reactors in chemistry, pharmacy or biotechnology
  • Thermal tests on test stands
  • Use in material tests

Integral XT Air-cooled process thermostats down to -80 °C

The LAUDA Integral XT process thermostats are ideally designed for the requirements of rapid and precise temperature control of an external application in process plant and pilot plant environments. The air-cooled process thermostats offer high performance in a small space while still providing functionality across a wide temperature range. Using the LAUDA Kryo 55 heat transfer liquid, temperatures from -50 up to 220 °C can be achieved without changing the heat transfer liquid. The special high-temperature version enables process temperatures up to 300 °C. This makes it ideal for reactor thermostating in chemical or pharmaceutical processes. The large expansion vessel in the LAUDA Integral XT absorbs temperature-induced changes in volume, thereby ensuring smooth operation even in large connected external systems.

Integral XT Water-cooled process thermostats down to -50 °C

Independent of variations in ambient temperature, Integral XT watercooled process thermostats achieve constantly high cooling performance. The temperature of the ambient air remains virtually unchanged thanks to the dissipation of the process heat through the cooling water. This is a particular advantage in setups similar to production as in process plants or in the mini-plant, where work is conducted under the most strained conditions. Water-cooled Integral XT systems are also the perfect choice for airconditioned spaces, since they do not tax or place an unnecessary burden on air-conditioning systems.

Integral XT Water-cooled process thermostats down to -90 °C

The new LAUDA Integral XT 1590 W and XT 490 W process thermostats stand out for their high cooling capacities at very low temperatures. Thanks to the two-stage cascade system, the thermostats are particularly suited for applications in the ultra-low range down to -90 °C. The water-cooled devices achieve cooling capacities of up to 18.5 kW and maximum heating capacities of 10.4 kW. The Integral XT 1850 W is also available with a heating capacity of 16.0 kW.

Integral XT High-temperature thermostats up to 320 °C

The LAUDA Integral XT high-temperature thermostats allow a maximum working temperature of 320 °C. The process thermostats are operated using the Command remote control, which is already utilized in the other XT models. The powerful pump can be regulated at eight different levels, supplying a maximum pressure of 2.9 bar and a flow rate of up to 45 L/min. The two models, XT 4 H and XT 4 HW, provide heating power of 3.5 kW. The XT 8 H and the XT 8 HW are equipped with an 8.0 kW heating system. With the XT 4 HW and the XT 8 HW models, water-generated counter-cooling allows for quick cool-down across the entire temperature range. Typical applications of the thermostats include distillation at high tempera­tures and control of high-temperature chemical syntheses.
