1. Intended use

JULABO circulators have been designed to control the temperature of specific fluids in a bath t ank . 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. Three menu keys facilitate adjusting setpoints, warning and safety functions and menu functions.

 Temperature- and time-dependent processes can be stored and executed using the

integrated programmer.

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

adjust the heat supply to the thermal requirements of the bath.

 The TCF - Temperature Control Features give the user access to all important

temperature control parameters. This means full control of the control behavior at all times and the ability to manually adjust or adapt the controls to the specific application.

 Absolute Temperature Calibration (ATC3) provides high temperature stability at all

points 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 entire 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, progr ammer in put).

 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 VFD COMFORT-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 shutdown 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 applications.

F34: The circulator fitted with a stainless steel bridge is placed on on the back of the bath tank leaving the bath open on the front side.

• 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 radiates to the environment. (Max. permissible ambient temperature: 40 °C). With regard to a disturbance in the cooling loop (leakage), the guideline EN 378 prescribes a certain room space to be available for each kg of refrigerant.

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

The necessary amount of refrigerant is specified on the type plate. > For 0.25 kg of refrigerant R134a, a room space of 1 m required. > For 0.52 kg of refrigerant R404A, a room space of 1 m required. > For 0.49 kg of refrigerant R507, a room space of 1 m

is req uired.

• Set selector dial for cooling machine in position "1" for operation with HE circulator.

(only F25, F34)

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

• 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

• No liability for use of other 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 control because it leads to calcification in the bath.

• Ferrous water can cause corrosion - even on stainless steel.

• Chloric water can cause pitting corrosion.

• Distilled and deionized water is unsuitable. Their special properties cause

Recommended bath fluids:

See website for list of recommended bath fluids.

ATTENTION: The maximum permissible viscosity is 70 mm

Caution:

Fire or other dangers when using bath fluids that are not recommended:

Please contact JULABO before using other than recommended bath fluids. Use only nonacidic and noncorrosive bath fluids.

JULABO assumes no liability for damage caused by the selection of an unsuitable bath liquid. Unsuitable bath fluids are fluids which, e.g.,

• are highly viscous

(much higher than recommended at the respective working temperature)

• have a low viscosity and have creep characteristics

• have corrosive characteristics or

• tend to crack.

5.3. Temperature application to external systems

Caution: Securely attach all tubing to prevent slipping.

If the circulator is operated without external system, close the pump connector (22)

Temperature application to external, closed systems

The circulator is used for temperature application to external, closed systems (loop circuit) with simultaneous temperature application in the circulator bath.

• Unscrew the M16x1 collar nuts on the pump connectors with a 19 mm (3/4“) wrench and remove the sealing disks. Using the collar nuts, screw on the tubing connection fittings (for tubing 8 mm or 12 mm in diameter) delivered with the unit and tighten firmly. (Pressure pump: 22, suction pump: 21)

• Push on the tubings, and secure with tube clamps.

• Attach the tubings to the connectors of the external closed

system, e.g., an instrument with a pressure-resistant temperatur e jacket or a temperature coil, and fasten with tube 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

At high working temperatures the tubing used for temperature application and cooling water supply represents a danger source. A damaged tubing line may cause hot bath fluid to be pumped out within a short time. This may result in:

• Burning of skin

• Difficulties in breathing due to hot atmosphere

Safety recommendations

• Employ suitable connecting tubing.

• Make sure that the tubing is securely attached.

• Avoid sharp bends in the tubing, and maintain a sufficient distance from

surrounding walls.

• Regularly check the tubing for material defects (e.g. for cracks).

5.4. Filling / draining

Notice:

• Pay attention to the thermal expansion of bath oil during heating to avoid overflowing of the liquid.

• Do not drain the bath fluid while it is hot! Recommendation: Temperature range 5 °C to 40 °C Check the temperature of the bath fluid prior to draining (by switching the unit on for a short moment, for example).

• Store and dispose the used bath fluid according to the laws for environmental

Filling

Take care that no liquid enters the interior of the circulator.

• Recommended maximum filling level with water as bath fluid: 30 mm below the tank rim

• Recommended maximum filling level with bath oils: 40 mm below the tank rim

 After filling, immerse the samples in the bath or place the lid on

the bath, in case the opening is not to be used.

 The circulator provides an early warning system for low level that

may be triggered when changing samples in the bath.

Warning:

For supervised or unsupervised operation with the “AUTOSTART“ function avoid any hazardous situation to persons or property

Take care to fully observe the safety and warning functions of the circulator.

Factory settings: OFF

The circulator has been configured and delivered by JULABO in accordance with the NAMUR recommendations. This means for the start mode that the unit must enter a safe operating status after a power failure. This safe operating status is indicated by the message „OFF“ or „R OFF“ on the VFD COMFORT-DISPLAY. A complete, all-pole shutdown of the main functional elements such as heater and pump motor is effected. The values set on the circulator remain saved and the unit is restarted by pressing the start/stop key in manual control. In remote control mode the values need to be resent by the PC via the interface. If such a safety standard is not required, the NAMUR recommendations can be bypassed with the AUTOSTART function thus allowing a direct

9.7. MENU ATC - Absolut Temperature Calibration

ATC serves to compensate a temperature difference that might occur between circulator and a defined measuring point in the bath tank because of physical properties.

Example: 1-point calibration

For ATC calibration, in steady state the bath temperature at the location of the temperature sensor (CT) is determined at the respective adjusted working temperature. This value is then set on the circulator in the menu >ATCalibration< under menu item > CTEMP X <. This can be a 1-point, 2-point or 3-point calibration.

3-point calibration

Principle:
