HUBER refrigerated bath circulators perform safe and repeatable heating and cooling tasks in the lab. 19 models covering the range -90 to 200°C with a selection of heating and cooling powers are available with air or water-cooled refrigeration machines.
A powerful variable speed pressure/suction pump allows the thermoregulation of objects in the bath or external applications. The pump speed is steplessly controlled. In combination with an optional pressure sensor the maximum pressure can be controlled. VPC (variable pressure control) ensures the best circulation and protects delicate glass apparatus from breakage due to overpressure.
Small volume and high heating and cooling powers result in the shortest heating and cooling rates. Displacement inserts can reduce the bath volume by half increasing this effect. Additionally the bath surface area is reduced and therefore the moisture absorption also. The calibration insert (optional) allows all HUBER refrigeration circulators to be used as calibration baths.
All models have Active Cooling Control for cooling power control at the maximum working temperature and an automatic cooling power regulation for energy saving operation and reduced heat dissipation into the lab. Depending on the model, carry handles or rollers are fitted for easy transportation. The drain is located on the front of the unit to enable simple drainage of the bath and the cover plate is thermoregulated to avoid condensation.
All models have the CC Pilot with Plug & Play technology: In the event of service the controller can be simply swapped. The CC Pilot can be used as a remote control (with data cable).
The CC Pilot is a high tech microprocessor based controller with a high precision measurement system for exact and reproducible results. The wide ranging functionality is supported by a large TFT display and simple operation. HUBER refrigeration circulators can be equipped with a ComG@te to enable integration in a process control system.
Depending on the bath dimensions objects can be thermoregulated in a bath. Typical applications for these classics are the thermoregulation of externally closed systems, e.g. photometer, refractometer, viscosimeter, double-jacketed reactors and autoclaves. They are used in miniplants, kilo labs, for stock point measurement, for low temperature calibration, for petroleum tests and many more applications.
