Unistat P920w
Dynamic temperature control system / circulation thermostat
Performance Characteristics
The Unistat range inspires with unique thermodynamic properties and a range of functions to meet the highest demands. Unistat technology guarantees precise, reproducible temperature control results, the shortest possible heating and cooling times and large temperature ranges without the need for fluid change. All Unistats are fitted with the innovative Pilot ONE controller with a 5.7“ touchscreen colour display and easy menu navigation. All important parameters can be seen at a glance and temperature curves are displayed in graphic real time.
Unistats are equipped with the most up-to-date pump technology for optimal heat transfer. The pump self regulates to ensure the best possible circulation and flow and delicate glass reactors are protected from breakage by the pumps soft start-up feature. Unistat technology impresses as a result of economic operation with reduced operating costs and efficient energy management. Because Unistats are hydraulically sealed, the service life of the temperature control fluid is dramatically increased by preventing oil loss through vapours and oxidation, further saving resources. Unistats are fitted with extensive safety equipment and are therefore suitable for unsupervised continuous operation. Relevant operating conditions are constantly monitored and the system is switched off if necessary or with the process safety feature the emergency cooling circuit is activated.

Product impressions
Controller
The new multi-touch controller Pilot ONE offers a brilliant 5.7" touchscreen with graphic functions and a comfortable navigation menu. All important operating parameters and temperature values are neatly displayed on the touchscreen. Thanks to the new favourites menu, the one-click operation and the integrated technical glossary the operation is very easy, just like on a smartphone. Integrated USB and Ethernet ports allows connection to a PC or network, e.g. for remote control or data transmission.

Please take further technical information as well as information about the scope of delivery, accessories and peripheral devices from the PDF data sheet. In cases of doubt the details given in there apply. If nothing to the contrary is quoted then the performance data referred is at an ambient temperature of 20°C.
Please observe the notes on installation and/or the space requirements of our products.
The following voltage and frequency tolerances apply based on EN60034-1:
Voltage +/- 5% for a frequency tolerance at the same time of +/- 2%
Examples to illustrate this: Not permissible, for example. is -5% on the voltage and +2% on the frequency. Permissible, on the other hand, are tolerances of -5% on the voltage and -2% on the frequency.
We reserve the right to make technical changes and correct errors. Illustrations can deviate from the original.
