Julabo HE: Refrigerated Circulators for Temperature Control of Media
Julabo HE refrigerated circulators are equipped with innovative technology and meet the highest demands. They are equipped with top-quality pressure and suction pumps that can be controlled electronically. The device is suitable for external temperature control of open and closed systems. Contact our team with any further questions.
Functions and features of the thermostats
The models of the series work with the highest precision. This is ensured by the ICC cascade control with a constancy of +/- 1 °C. They are equipped with a VFD display , which offers maximum convenience. Actual and setpoint values are displayed externally and internally with a resolution of 0.01 °C.
The integrated programmer can be set in once ten steps. In addition, an RS232 interface and a real-time clock are available. The pressure and suction pumps can be adjusted in steps. They automatically adapt to the viscosity behavior.
The units are primarily suitable for external temperature control. Temperature control of open systems and large consumers is also possible. However, you can also temper smaller objects in the thermostat bath.
There are different models of the series Top- and Hightech. Here, the equipment features and bath sizes differ. Accessories are also available, for example bath inserts or bath covers. If you have any questions about accessories, we will be happy to inform you.
High-quality and temperature-stable: modern design and practical equipment
The equipment includes in particular the VFD display and an LCD dialog display, with which you can interactively operate the thermostat in plain text.
With the help of the membrane keypad, you set the setpoints and menu functions, as well as the warning and safety values. The ICC temperature control is self-optimizing. Furthermore, the TFT Temperature Control features are available to improve the control behavior.
Additional details include ATC3 3-point calibration and Pt100 external sensor connection, allowing you to control and measure external systems. The Smart Pump features pump performance levels that you can set electronically. You set the over-temperature protection on the display. There is an RS 232/RS 485 interface that allows you to communicate online.
The integrated programmer is suitable for a total of 6 x 6 program steps, and the Stakei sockets are suitable for an HSP booster pump and a cooling water solenoid valve.
The flow rate of the pumps is 22 to 26 liters per minute, the delivery pressure in bar is 0.4 to 0.7 bar, while the maximum suction capacity is 0.2 to 0.4 bar. In addition, the Profibus digital interface is available separately.
Technical data at a glance
Finally, you will be provided with additional technical data that may be of importance when working with the circulators.
The dimensions are 21 cm x 42 cm x 40 cm in width, depth and height. The weight is in a low range with eleven kilograms. In addition, the filling volume is specified at 4.4 liters . The devices operate at 230 volts and 50 hertz.
They are assigned to the IP 21 degree of protection. Therefore, they are protected from finger contact and receive protection against foreign bodies and dripping water. Thus, the thermostats can be used in humid environments.
