Description
The Huber Unistat 825 (1079.0004.01) is a cutting-edge dynamic temperature control system built for precision and performance in pilot plant, kilo lab, and industrial-scale thermal applications. With a wide operating range from -85°C to +250°C and advanced process control via the Pilot ONE touchscreen controller, the Unistat 825 delivers fast temperature change rates, exceptional stability, and unparalleled thermal uniformity.
Designed for demanding external circulation, it is compatible with reactors, double-jacketed vessels, distillation systems, and more. The closed-loop system minimizes fluid loss and oxidation, while the integrated heater, cascade refrigeration, and efficient circulation pump provide reliable operation under continuous loads.
Whether used in chemical synthesis, materials R&D, or pharmaceutical process development, the Unistat 825 represents the highest standard in thermal process control.
