Huber Grande Fleur

Category Dynamic Temperature Control Systems
Manufacturer Huber
Country of manufacture Germany

The new Grande Fleur expands the product offering in the dynamic temperature control range. The Grande Fleur together with the Petite Fleur are two small Tangos and are the entry level into the world of Unistat technology.

The compact dimensions and unique thermodynamics of the Grande Fleur mean it is ideally suited for high precision temperature control of research reactors. The Grande Fleur offers all of the great performance and features of the Unistat series, achieving unrivalled heating and cooling rates.

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 favorites 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. The E-grade Explore turns a Unistat into a development tool for process and chemical engineering.
