Petite Fleur: Efficient temperature control system for laboratory applications

publication date: Jun 17, 2020
author/source: Huber


The Petite Fleur models are the smallest dynamic temperature control systems in the Unistat range.

They are designed for highly accurate temperature control of small research reactors. As all Unistats, the Petite Fleur models have unique thermodynamic properties. Recent comparative studies show that the Petite Fleur is currently the most efficient temperature control system of its class. In most cases, it cools and heats significantly faster than comparable competitor models. The differences in the housing volume are likewise impressive: In direct comparison, the housing of the Petite Fleur is up to 50 % smaller.

Go to to see case studies with different reactor systems.

The Petite Fleur models reach operating temperatures of -40 °C to +200 °C and offer a refrigeration capacity of 480 W (with full pump capacity acc. to DIN 12876). With a capacity of up to 25 l/min, the circulation pump provides for optimum heat transmission. Delicate glass reactors are protected from damage with the soft start-up, and changes in the viscosity within the fluid circuit are compensated for.

The Petite Fleurs furthermore comprise the touchscreen controller Pilot ONE with its large 5.7“ colour display, USB and network connections, programmer, calendar / timer function, and clearly understandable operator menus in 13 languages. As a standard, all models come filled with environmentally friendly natural refrigerant.
