Huber Chili Dynamic Temperature Control System

Category Dynamic Temperature Control Systems
Manufacturer Huber
Country of manufacture Germany

Chili is the latest heating circulator for closed systems in the Unistat product family. The compact heating thermostat is equipped with the E-grade Professional as standard and convinces with excellent thermodynamic properties and a range of functions for the highest demands. Chili guarantees highly accurate, reproducible temperature control results with short heat-up times and wide temperature ranges without changing fluids. Like all Unistats, the Chili is equipped with the innovative Pilot ONE controller with 5.7" touch screen and convenient menu navigation.

The economically Unistat technology provides minimized operating costs and efficient energy management. A further advantage is the extended life-time of the thermofluid. The hydraulically sealed systems prevent the formation of oil vapors and oxidation. Chili is the smallest heating thermostat in the Huber product range that is approved for use with Marlotherm as a thermofluid. For controlled cooling, an external cooling coil (unregulated) is available as an optional accessory. Due to ist technical properties and low purchase price, Chili is ideally suited for distillation tasks in botanical extraction, for example.

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.
