This recirculating chiller is designed for highest requirements in industrial use.

Special features

This model series offers short cooling times and at the same time a high efficiency as well as an economical alternative to cooling with appropriate tap water. With its compact design, the unit can be installed in a space-saving manner. This unit has a bright LED temperature display, which is easy to read even from a distance.

Some models in this series (with the type suffix "W") are low-noise water-cooled and produce very little waste heat. There are warning and safety functions for reliable continuous operation. A filler opening allows quick filling and a drain cock allows uncomplicated draining of the recirculating chiller.

There are other devices from the manufacturer available in addition to this model. For example, there are the Julabo FC and the Julabo FL with different cooling capacities.

High quality, functional design

The device corresponds to modern, functional design. Thus, the recirculating chiller is located on casters, with which it can be moved comfortably. At the front there are struts for dust collection, which can be easily cleaned.

An on/off button can be operated and there is also an LED display and corresponding input keypad.
