1. Intended use
JULABO Cryo-Compact Circulators have been designed for temperature application to
specific fluids in a bath tank. The units feature pump connections for temperature control of
external systems (loop circuit).
JULABO circulators are not suitable for direct temperature control of foods,
semi-luxury foods and tobacco, or pharmaceutical and medical products. Direct
temperature control means unprotected contact of the object with the bath
medium (bath fluid).

The Cryo-Compact Circulators are operated via the splash-proof keypad.
The implemented microprocessor technology allows to set and to store the
setpoint that can be indicated on the LED temperature display.

The PID temperature control adapts the heat supplied to the thermal
requirements of the bath.

Safety installations conforming to IEC 61010-2-010
The excess temperature protection is a safety installation independent from
the control circuit.
The safety value is set using a tool (screwdriver).
If the low level protection device is triggered, a complete shutdown of the
heater and circulating pump is effected.

The serial interface RS232 allows modern process technology without
additional interface.
2. Operator responsibility – Safety instructions
The products of JULABO ensure safe operation when installed, operated, and maintained
according to common safety regulations. This section explains the potential dangers that may
arise when operating the circulator and also specifies the most important safety precautions to
preclude these dangers as far as possible.
The operator is responsible for the qualification of the personnel operating the units.
 The personnel operating the units should be regularly instructed about the dangers
involved with their job activities as well as measures to avert these dangers.
 Make sure all persons tasked with operating, installing, and maintaining the unit have read
and understand the safety information and operating instructions.
 When using hazardous materials or materials that could become hazardous, the circulator
may be operated only by persons who are absolutely familiar with these materials and the
circulator. These persons must be fully aware of possible risks.
