applications.

1. Intended use

JULABO circulators 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).

luxury foods and tobacco, or pharmaceutical and medical products. Direct temperature control means unprotected contact of the object with the bath

1.1. Description

 The circulators 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 VFD COMFORT-DISPLAY and LCD DIALOG-DISPLAY. Three menu keys facilitate adjusting setpoints, warning and safety functions and menu functions.

 The integrated programmer allows storing and running temperature and time-

dependent processes.

 The control electronics including “ICC - Intelligent Cascade Control“ automatically

adapts the heat supplied to the thermal requirements of the bath.

 The TCF - Temperature Control Features allow the user to have access to all

important temperature control parameters. This means: Full control on the control mode and the chance to manually adjust or adapt control to the specific application.

 Absolute Temperature Calibration (ATC3) provides 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, switchable from RS232 to RS485, allows modern process technology without additional interface. Connection for Pt100 external sensor for external temperature measurement and control. Alarm output for external alarm message or control of JULABO refrigerating baths or solenoid valve (cooling water). The electronic module (option) provides 3 further analog connections (alarm input, standby input, recorder output, programmer input).

 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 LCD DIALOG-DISPLAY.

 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.

 Intelligent pump system: The pump capacity (electronically adjustable via the motor

speed) enables to adapt to varying conditions for internal and external temperature

material.

• Cooling machine, pump motor and electronics produce intrinsic heat that is dissipated via the venting openings! Never cover these openings!

• Keep at least 20 cm of open space on the front and rear venting grids.

• The place of installation should be large enough and provide sufficient

air ventilation to ensure the room does not warm up excessively because of the heat the instrument rejects to the environment. (Max. permissible ambient temperature: 40 °C). For a fault (leakage) in the refrigeration system, the standard EN 378 prescribes a certain room space to be available for each kg of refrigerant. The refrigerant quantity is specified on the type plate.

• Place the unit on an even surface on a pad made of non-flammable

is required.

• Do not set up the unit in the immediate vicinity of heat sources and do not expose to sun light

• Before operating the unit after transport, wait about one hour after setting it up. This will allow any oil that has accumulated laterally during transport to flow back down thus ensuring maximum cooling performance of the compressor.

• Set selector dial for cooling machine (23) in position "1" for operation

5.2. Bath fluids

Carefully read the safety data sheet of the bath fluid used, particularly with regard to the fire point! If a bath fluid with a fire point of ≤65 °C is used, only supervised operation is possible.

Water: The quality of water depends on local conditions.

• Due to the high concentration of lime, hard water is not suitable for temperature

Only water cooled models:

Ensure circulation of cooling water by connecting the tubing to cooling water inlet and outlet on the rear of the refrigerated circulator.

clamps to prevent slipping.

Temperature application to external, open systems

The circulator is equipped with both a pressure and suction pump for external temperature application in open systems.

Differing flow rates of the pressure and suction pumps should be compensated. To maintain a constant liquid level, the JULABO „D+S“ Level Adapter is recommended for the external bath tank. The flow rate of the pressure pump will be then regulated by a built-in float device. The liquid level may be changed by a height adjustment on the „D+S“ Level Adapter.

Accessory: „D+S“ Level Adapter Order No. 8 970 410

Important:

 The liquid level should be equal in the internal and external

baths (absolute height).

 If you take out samples (for example Erlenmeyer flasks) from

the external bath, turn the circulator off with the Start/Stop key.
