Performance Characteristics

A new chapter in high-precision temperature control has been opened with the new Unistat generation. State-of-the-art technology has been added to the proven concept for even better temperature control performance. Unistat process thermostats impress with excellent thermodynamic properties and a range of functions to meet the highest demands. Unistats guarantee high-precision and reproducible temperature control results, short heat-up and cool-down times and large temperature ranges without inconvenient fluid changes. To ensure an optimum heat transfer, the units are equipped with a state-of-the-art, seal-free circulation pump featuring a magnetic coupling. The improved venting and degassing functions enable fast commissioning and trouble-free operation.
The innovative Pilot ONE controller with 5.7" touchscreen colour display is used for operation. Important parameters can be seen at a glance and temperature curves are displayed graphically in real time. To provide comprehensive connectivity, the "Com.G@te DIGITAL" with the most important digital interfaces is included as standard. Analogue interfaces can be retrofitted via the optional "Com.G@te PLUS".
The Unistat technology also offers impressive economic benefits with minimised operating costs and an efficient energy management. Another advantage is the increased durability of the temperature control fluid. Sealed hydraulically, the systems prevent the formation of oil vapours and oxidation. The Unistats are fitted with extensive safety features and are therefore ideally suited for unsupervised continuous operation. Relevant operational states are permanently monitored and, if necessary, the system is switched off or emergency circuits are activated. All safety circuits are designed in accordance with Performance Level C or higher (DIN EN ISO 13849-1).

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.
