3.1 Function description of the temperature control unit
3.1.1 General functions
The heating circulators are temperature control units ideally suited for the thermoregulation of
baths.
Due to the powerful heat technology,short heating times can be achieved.
3.1.2 Other functions
A pump ensures the thermal fluid is circulated. The following data are displayed on the display with
OLED technology depending on the model and options: temperature of the internal and external
temperature sensor, setpoint. Use the membrane keyboard to enter the controller settings.
The temperature control unit can easily be integrated in many laboratory automation systems using
the standardly existing RS232 and USB interfaces on the controller .
An external Pt100 sensor can be connected via the optional Pt100 process display sensor port . The
temperature measured is displayed on the display.
Temperature control units with a heater have an overtemperature protection to DIN EN 61010-2-
010 that is independent of the control circuit.
3.2 Information on the thermal fluids
Non-compliance with the safety data sheet for the thermal fluid to be used
INJURIES

Risk of injury to the eyes, skin, respiratory tract.

The safety data sheet for the thermal fluid to be used must be read prior to using it and its
content must be respected.

Observe the local regulations/work instructions.

Wear your personal protective equipment (e.g. temperature-resistant safety gloves, safety
goggles, safety footwear).

Danger of slipping because floor and work area are contaminated. Clean the work station and
follow the instructions for the disposal of thermal fluid and material on page 15 in section
»Proper disposal of resources and consumables« .
Non-compliance with the compatibility between the thermal fluid and your temperature control
unit
MATERIAL DAMAGE

Observe the classification of your temperature control unit according to DIN 12876.

Ensure the following materials are resistant with respect to the thermal fluid: Stainless steel
1.4301/ 1.4401 (V2A), copper, nickel, FKM, red bronze/brass, silver solder and plastic.

The maximum viscosity of the thermal fluid must not exceed 50 mm²/s at the lowest working
temperature!

The maximum density of the thermal fluid may not exceed 1 kg/dm³!
Mixing different thermofluids in a thermal fluid circuit
PROPERTY DAMAGE

Do not mix different types of thermofluid (such as mineral oil, silicone oil, synthetic oil, water,
etc.) in a thermofluid circuit.

The thermal fluid circuit must be rinsed when changing from one type of thermal fluid to an-
other. No residues of the previous type of thermal fluid may remain in the thermal fluid circuit.
