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).

foods and tobacco, or pharmaceutical and medical products. Direct temperature control

1.1. Description

 The Cryo-Compact 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 DIALOGDISPLAY. 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). 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 applications..

Temperature application to external, closed systems

• 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: 14, suction pump: 15)

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

• Attach the tubing to the connectors of the external closed system, e.g., an instrument with a pressure-resistant temperature jacket or a temperature coil, and fasten with tube clamps to prevent slipping.

Temperature application to external, open systems

S = Suction pump connection D = Pressure pump connection K = Float

The Cryo-Compact 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.

6.3. Tubing

Cryo-Compact Circulators

At high working temperatures, the tubing used for temperature control and for the cooling water supply represents a danger source. A damaged tubing line may allow a large amount of hot bath fluid to be pumped out within a short time.

This may result in:

• Burning of skin

• Breathing difficulties due to hot atmosphere

Safety instructions

• Use 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), at least once a year.

Recommended tubing:

6.4. Bath fluids

Carefully read the material 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 scale in the bath

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

• Chlorinated water can cause pitting corrosion.

• Distilled water and deionized water are unsuitable. Their special properties

Recommended bath fluids:

ATTENTION: The maximum permissible viscosity is 70 mm

See website for list of recommended bath fluids.

Caution:

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

Please contact JULABO before using other than recommended bath liquids.

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

• are highly viscous

(much higher than 70 mm2 /s at the respective working temperature)

• have a low viscosity and have creep characteristics

• have corrosive characteristics or

• tend to crack.

Note:

The temperature system has been configured and supplied by JULABO according to N.A.M.U.R. recommendations. This means for the start mode, that the unit must enter a safe operating state after a power failure (non-automatic start mode). This safe operating state is indicated by „ OFF „, resp. R OFF on the VFD-COMFORT-DISPLAY. A complete shutdown of the main functional elements such as heater and circulating pump is effected simultaneously.

The values set on the Cryo-Compact Circulator remain stored, and the unit is returned to operation by pressing the start/stop key (in manual control mode). In remote control mode, the values need to be resent by the PC via the interface.

Should such a safety standard not be required, the AUTOSTART function (automatic start mode) may be activated, thus allowing the start of the instrument directly by pressing the mains power switch or using a timer.

 The AUTOSTART function can only be used, if setpoint setting is carried

out via >keyboard< or >eprog< or >ext. Pt100<.

Warning:

For supervised or unsupervised operation with the AUTOSTART function, avoid any hazardous situation to persons or property. The instrument does no longer conform to N.A.M.U.R. recommendations.

Resetting time >Tn< (Integral component)

Compensation of the remaining control deviation due to proportional regulation. An insufficient resetting time may cause instabilities to occur. Excessive resetting time will unnecessarily prolong compensation of the control difference.

Lead time >Tv< (Differential component)

The differential component reduces the control settling time. An insufficient lead time will prolong the time required to compensate for disturbance effects and cause high overshooting during run-up. An excessive lead time could cause instabilities (oscillations) to occur.

Proportional range >Xpu<

The proportional range Xpu of the cascaded controller is only needed for external control.

2. Connect an external contact ‚AK‘ (e.g. for emergency switch-off) or an alarm contact of the superordinated system.

In case the connection between Pin 2 and Pin 3 is interrupted by opening the contact ‚AK‘, a complete shutdown of the circulating pump and heater is effected, and the unit enters the condition „E OFF“. As long as the contact remains open, line 4 of the LCD DIALOGDISPLAY flashes and displays the message „STAND-BY“.

If the contact is reclosed, the instrument returns to the standby state and

„ E OFF „ is displayed. Press

 Additional tips for using the STANDBY input:

The standby function can be used in conjunction with the AUTOSTART feature (see page 33).

1. If the Autostart function is NOT turned ON, the standby input is used as described above.

2. If the Autostart function is enabled, the instrument will revert back to the original method of entering the setpoint (i.e. keypad, RS232, Analog input, etc.).

• Entering the setpoint with the keypad. e.g. As described above, a bipolar shut-down is accompanied by the „STAND-BY“ display and the OFF state. The programmable controller starts again when the contact is reclosed. The temperature of the bath fluid changed during the STAND-BY state.

• Entering the setpoint with the programmer (see pages 44). The display „STAND-BY“ appears. The setpoint value and the time are both held at the current value. The temperature of the bath fluid will be held the contact is reclosed.

The limits IntMax and IntMin are only valid for external control. IntMax and IntMin are used to limit the expected internal bath temperatures to any upper

it would be required for reaching the temperature in the external system. Consequently the external setpoint may thus not be reached.

Sense of a limit setting:

>SafeTemp:<

 Protects the bath fluid from overheating.  Prevents an undesired alarm shut-down by the excess temperature

protection - >ALARM CODE 14<. Set >IntMax:< to a value at least 5 °C below the >SafeTemp:< value.

 Protects the pump motor from high viscosity of the bath fluid at low

temperatures.

 For refrigerated Cryo-Compact Circulator s: Freezing protection when using

water as bath fluid.

For the heat-up and cool-down phases different settings to conform to the requirements of the particular application are possible.

Setting range: 0 ... 200 °C

Using Upper band and Lower band, the difference between the temperatures in the internal bath and the external system can be limited to any maximum value for the heat-up or the cool-down phase.

During the heat-up phase the difference value always adds to the actual external temperature. During the cool-down phase, the difference value is subtracted.

Sense of a band limit:

 Ensures gentle heating for the objects requiring temperature application.  Protects glass reactors, for example, from thermal shock.

 The IntMax: and IntMin: values are superordinated to this band limit.

9.8. ATC Absolute Temperature Calibration, 3-point calibration

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

Sensor: >intern<, >extern<

Calibration can be carried out for the internal temperature sensor and for the external temperature sensor connected to the socket „ext. Pt100“. The Cryo-Compact Circulator is able to store both parameter sets. However, only the one set under this menu item is indicated.

Status:

>no< The controller of the Cryo-Compact Circulator uses the

original curve of the temperature sensor. Important: During the calibration process >no< needs to be set.

>yes< The controller of the Cryo-Compact Circulator uses the new calibration curve.

1-point calibration

Type:

A >1-point<, >2-point < or >3-point < calibration can be carried out. First geometrically define the location for calibration (measuring point

), then determine the temperature values of of the calibration

points. The calibration type also determines the number of pairs of values indicated on the LCD DIALOG-DISPLAY.

TmpValue: 1 or 2 or 3

Defined temperature value of the calibration point. This value is automatically stored with >CalValue< and can be indicated for control purposes.

CalValue: 1 or 2 or 3

The „Calibration value“ is determined with a temperature measuring device and stored under menu item >CalValue<.

Principle: For ATC calibration, in steady state the bath temperature at the location of the temperature sensor (T

) is determined at the respective adjusted

working temperature. This value is then set on the Cryo-Compact Circulator in the menu >ATCalibration< under menu item >Calvalue X<. This can be a 1-point, 2-point or 3-point calibration.
