The new Cryo-Compact Circulators 'CF Series' offer a small package of powerful refrigeration technology.

With the introduction of the new CF series, Julabo presents four compact refrigerated/heating circulators.

These units are characterised by their small, compact dimensions of only 24 x 46 x 40 cm and 28 x 46 x 46 cm (W x L x H).

The compactness of these units allows users to free up bench space.

Combined with the possibility of operating the units in ambient temperatures up to +40C, the efficient, well designed ventilation of the units allows them to be placed side by side, or under a fume hood.

The models are divided into the 'Economy' Series (CF30 and CF40 models) with working temperatures from -30C or -40C up to +150C, and the 'HighTech' Series (CF31 and CF41 models) with working temperatures from -30C or -40C up to +200C.

Depending on the model, cooling capacities up to 470 watts can be attained.

The 'HighTech' models utilise an intelligent, self-optimising ICC cascade temperature control, providing a stability of +/-0.02C.

Additional features include a VFD display and an LCD display for interactive operation in easy-to-read text, 3-point temperature calibration, a connection for an external Pt100 sensor, a RS232/485 interface, an integrated programmer and an early warning system for low liquid level.

These models also feature a powerful pressure and suction pump with an electronically adjustable flow rate between 22-26 l/min and a pressure capacity of 0.6 to 1.1bar.

The 'Economy' models utilise PID temperature control, providing a stability of +/-0.03C.

The temperature is indicated via a LED display.

The pressure pump capacity provides up to 15 l/min or 0.35 bar.

All four models offer a heating capacity of 2 kW and conform to DIN 12876-1 safety class 3.

All models feature pump connections for external temperature applications as well as a bath opening, enabling temperature control of small objects, which can be placed directly in to the bath.
