2. General
2.1 Description of the device
The flow controller complements the function of the Integral XT process thermostat by receiving the flow of
heat transfer liquid and regulating it by means of a valve. At the pressure output of the flow meter, there is
an internal temperature sensor that allows temperature control at this point or allows the values to be read
out.
In the case of devices with a higher-pressure pump, it is also possible to increase the flow pressure and
thus the flow within the device parameters.
The flow controller is equipped with a bypass as the Integral XT process thermostat requires a minimum
flow rate of 5 L of heat transfer liquid per minute for optimum heating and cooling capacity. If the flow in the
flow meter is lower, the bypass must be opened to ensure that there is a sufficient quantity of heat transfer
liquid flowing back into the Integral XT before flow measurement.
2.2 Intended use
The device is an accessory for the Integral XT process thermostat and has the function of regulating the
flow quantity in the range of 0.2 to 20 L/min. The heat transfer liquid must have a minimum conductivity of
1 µS/cm and be operated within its working temperature range. Silicone oils and mineral oils are not
suitable.
Devices with an additional pump offer the ability to increase the flow pressure.
The device may only be operated in accordance with the intended procedures and under the conditions
specified by these operating instructions and the operating instructions of the Integral XT process
thermostat. Any other type of operation is considered to be unintended can impair the protection provided
by the device.
LAUDA does not accept liability in the case of damage caused by improper use of the device.
2.3 Non-intended use
The device may not be used:
for medical or pharmaceutical applications.
in potentially explosive areas.
with combustible, flammable, highly flammable or explosive heat transfer liquid or silicone oil.
if the permissible working temperature range of the heat transfer liquid is exceeded.
in outdoor installation.
to heat or cool food.
