Congratulations!
You have made an excellent choice.
JULABO thanks you for the trust you have placed in us.
This operating manual has been designed to help you gain an understanding of the operation and
possible applications of our circulators. For optimal utilization of all functions, we recommend that you
thoroughly study this manual prior to beginning operation.
The JULABO Quality Management System
Temperature control devices for research and industry are developed,
produced, and distributed according to the requirements of ISO 9001 and
ISO 14001. Certificate Registration No. 01 100044846
Unpacking and inspecting
Unpack the circulator and accessories and inspect them for possible transport damage. Damage
should be reported to the responsible carrier, railway, or postal authority, and a damage report should
be requested. These instructions must be followed fully for us to guarantee our full support of your
claim for protecting against loss from concealed damage. The form required for filing such a claim will
be provided by the carrier.

Recirculating Cooler

Operating manual
1. Intended use
JULABO recirculating coolers have been designed to control the temperature of specific fluids in a
bath tank. The units feature pump connections for temperature control of external systems (loop
circuit). JULABO recirculating coolers 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).
1.1. Description

ATC

RS232
PUMP
SMART
;The recirculating coolers are operated via the splash-proof keypad. The
implemented microprocessor technology allows to set and to store different values
that can be indicated on the MULTI-DISPLAY (LED). Three menu keys facilitate
adjusting setpoints, warning and safety functions and menu functions.
;The PID temperature control adapts the heat supplied to the thermal requirements
of the bath.
;Absolute Temperature Calibration (ATC3) provides a high temperature stability in
the bath. With the 3-point calibration an offset is adjusted at three temperatures to
ensure an accurate temperature pattern at the selected spot in the bath over the
full temperature range.
;Electrical connections:
The serial interface RS232 allows modern process technology without additional
interface.
;The excess temperature protection conforming to IEC 61010-2-010 is a safety
installation independent from the control circuit. This protection can be indicated
and set on the MULTI-DISPLAY (LED).
;The early warning system for low level signals that bath fluid needs to be refilled
before the low level protection conforming to IEC 61010-2-010 causes a complete
shut-down of the main functional elements.
;The pump capacity (electronically adjustable via the motor speed) enables to adapt
to varying conditions for internal and external temperature applications.
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.
