Precision Thermoregulation

Precision thermoregulation

Unistats have the most up-to-date pump technology and provide optimal recirculation to increase the through-flow volume and significantly improve heat transfer to an object. The rapid response in programmed temperature changes help deliver predictable and reproducible results.

Secure Process

Process Security

Unistats provide assurance that temperature-dependent processes in your laboratory or production processes will run exactly as required

Unistat and Tango Thermoregulators

Unistats are not comparable with conventional temperature control engineering: there are no alternatives thermodynamically

  • Safe

    Designed for demanding temperature control applications requiring the highest safety standards

  • Dynamic

    Hydraulically-sealed, re-circulating thermostats for temperatures between -125 °C and +425 °C

  • Accurate

    The ideal choice for accurate and responsive control of a wide variety of applications in the pharmaceutical, chemical, petrochemical and semi-conductor markets

Process Safety

  • Unistats provide an option to allow the circulation pump and compressor to continue to work despite an over temperature trip. This allows controlled heat removal and protects your thermally controlled products from being destroyed.


  • Unitstats only require de-gassing after each application set up. As a result uncontrolled conditions during normal operation will be minimised.

Hydraulically sealed

  • Volume changed due to fluid temperature fluctuations are equalised by the expansion vessel. The fluid in the expansion vessel hydraulically seals the fluid circuit and prevents early oxidation.

Touchscreen Colour Display

  • The large, graphic touchscreen aids operation and shows convenient display of temperature runs directly on the machine. Therefore essential application parameters are always in view.


  • Unistats offer numerous possibilities for data communication. RS232, Ethernet and USB interfaces are fitted as standard, as well as various analogue interfaces.

Temperature Control

  • The intelligent temperature control TAC analyses the controlled fluid circuit continuously, and adjusts the control parameters automatically. The result is the best control results even with difficult applications.

Pressure Control

  • The pressure control VPC continuously monitors the pressure in the connected application and therefore protects the sensitive glass reactor from breakage.


  • Unistats have a high power to volume ratio (Watts/Litre). In practice, Unistats offer a very high speed of temperature change in the region of several hundreds of Kelvin per hour.

Space saving design

  • Unistats have a compact design requiring little space. The power to volume ratio (Watts/cm) according to DIN12876 documents the extremely small space requirement of the Unistats.

Heat Transfer

  • Powerful circulation pumps and a large hose cross section ensure maximum flow rates and optimum heat transfer.
