New Cooling Powers

Huber has extended the Unistat range of highly dynamic temperature control systems with four new models. The Unistats 905, 905w, 912w and 915w have been designed for tasks in process and chemical engineering such as
temperature control of reactors, autoclaves, mini and pilot plants, reaction blocks and calorimeters. These temperature control systems offer unique thermodynamics for highly precise and reproducible temperature control results. Unistat technology guarantees quick cooling and heating rates as well as wide temperature ranges without the need to change the thermal fluid.

All new models cover a temperature range from -90°C to +250°C and have heating powers of 6 kW. Depending on
the model, the new Unistats have cooling powers from 4.5 kW up to 11 kW. Unistats are also equipped with a 5.7”
colour TFT display for easy control. The display shows allimportant parameters at a glance and is even capable of
illustrating temperature processes in graphic and real time. Powerful speed regulated circulation pumps with delivery
rates up to 110 l/min guarantee an ideal circulation and the soft start protects glass reactors against breakage.

Unistats offer efficient energy management to reduce running costs. The hydraulically sealed construction reduces
the formation of oil vapours and oxidation extending the lifetime of the thermal fluid by years. Safety features allow
the system to run unsupervised for continuous operation. In case of a failure, warnings are given out, the system
switches off or emergency circuits are activated. Further features are: programmer, adaptive cascade control, ramp
function, calendar function, adaptive user menus, sensor calibration as well as analogue and digital interfaces.

The optional WebG@te module offers further connections such as Ethernet and USB. The unit can be remote
controlled via the company network and the Internet. Temperature profiles and measurement data can be stored
directly on a USB data storage medium. Connection into a process control system is possible via the interfaces.
