Recirculating coolers

Huber Unistat dynamic temperature control systems form the entry point into highly dynamic temperature control for laboratory, pilot-plant and industrial use, with Unistats down to -45°C in the Petite Fleur, Grande Fleur, Tango and 400-series lines offering compact dimensions and unique thermodynamics for high-precision temperature control. Unistats down to -60°C are predestined for chemical process and reaction engineering applications such as temperating reactors, autoclaves, miniplant/pilot plants, reaction blocks and calorimeters, while Unistats down to -120°C guarantee the shortest heat-up and cool-down times and wide temperature ranges without troublesome fluid changes, enabling professional scale-up from research lab to production plant with consistently stable process conditions. High-temperature Unistats up to +425°C set standards for safety, operating comfort and temperising speed thanks to a minimized internal volume, while dedicated Unimotive models serve automotive-industry applications using water-glycol mixtures with corrosion protection down to -45°C.

Key features:

• Unistat lines down to -45°C, -60°C and -120°C for different applications

• High-temperature Unistats operating up to +425°C

• Unique thermodynamics for high-precision, reproducible results

• Professional scale-up from research lab to production plant

• Unimotive models for automotive temperature-simulation testing

Typical applications:

• Temperating reactors, autoclaves, miniplants and calorimeters

• Chemical process and reaction engineering

• Automotive component and battery temperature-stress testing

Huber recirculating chillers span from compact Minichiller and Unichiller models up to 2.5 kW cooling capacity — a cost-effective, environmentally friendly cooling solution needing little space, ideal for cooling laboratory equipment, distillation apparatus, vacuum pumps and rotary evaporators — through Unichiller models up to 10 kW offering best efficiency, stable pressure and flow performance and constant cooling-water temperature for heat removal in biological and chemical processes and technical plant cooling. Tower-design Unichiller units up to 80 kW, with a small footprint and air- or water-cooled refrigeration machines, serve as central cooling-water supply for industrial and chemical processes, while circulating heat exchangers and the compact, economical CS Chiller line round out the range with a secondary cooling circuit and system-separator function.

Key features:

• Minichiller/Unichiller up to 2.5 kW for compact laboratory cooling

• Unichiller up to 10 kW with stable pressure, flow and temperature

• Tower-design Unichiller up to 80 kW for central cooling-water supply

• Circulating heat exchangers acting as a system separator between circuits

• CS Chiller line for compact, cost-effective cooling

Typical applications:

• Cooling laboratory equipment, distillation apparatus and vacuum pumps

• Heat removal in biological and chemical process work

• Central cooling-water supply for industrial and chemical plants

Huber baths and circulators cover a full range of open-bath temperature control, from classic heating thermostats in the CC and KISS model lines through to heating-cooling thermostats with a refrigeration unit and open bath suitable for laboratory and industrial heating and cooling tasks down to -90°C. Visco baths, equipped with transparent polycarbonate baths and a counter-cooling coil, serve capillary viscometer and densitometer measurement tasks, while circulating heaters provide temperature control for externally connected open systems in a compact design with a stainless-steel circulation pump suitable for installation in plant equipment. A dedicated beer-forced-aging-test thermostat with an integrated program generator cycles temperature between 0°C and 60°C to induce artificial beer aging for quality testing.

Key features:

• Heating thermostats (CC, KISS series) with classic open-bath design

• Heating-cooling thermostats operating down to -90°C

• Visco baths with polycarbonate bath and counter-cooling coil

• Circulating heaters with stainless-steel pump for external systems

• Beer-forced-aging-test thermostat cycling 0-60°C

Typical applications:

• Capillary viscometry and densitometry measurement

• Laboratory and industrial heating/cooling down to -90°C

• Beer quality testing via forced-aging temperature cycling
