Huber Ministats are the smallest cooling circulator in the world. Their small dimensions allow Ministats to be placed in the smallest of spaces, for example in a laboratory fume cupboard or inside technical plant. Despite their minimal size the systems are extensively fitted out and offer sufficient performance for temperature control of photometers, refractometers, viscometers, distillation apparatus, reaction vessels and mini-plants. The main applications are using external applications however the bath opening allows objects to be thermoregulated directly in a thermostat bath. A powerful pressure/suction pump with an infinitely controlled rotational speed ensures optimal circulation. The maximum pressure can also be regulated by an optional pressure sensor, meaning that sensitive glass reactors and apparatus can reliably be protected from breakage. Additionally, Ministats offer the Pilot ONE controller as standard with a colour TFT display and comfortable operator guidance. Analogue connections according to NAMUR are available via the optional Com.G@te module allowing Ministats to integrate into plant and process control systems.

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 favourites 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.
