Area of application

The heated hoses can be used in many industrial fields under the operating conditions
specified in the present instructions for installation and operation. The area of application
ranges from freeze protection, e.g., -20°C, via temperature maintenance to temperature
increases up to max. 200°C. The standard nominal voltage of the heated hoses is 230V
(other supply voltages are possible!). The maximum permissible ambient temperature
(environment) spans from –20°C to + 40°C.
Suitable temperature control devices (controller/cut-out unit) must be provided to ensure
that the max. Fluid temperature is not exceeded. The heating power depends on the hose
length and cross-section. You will find the exact data specified on the yellow type plate
attached to the electrical connecting cable.
NOTE
Different ambient temperatures along the hose route will result in different internal
temperatures. For regulated heated lines the decisive factor for temperature control is the
ambient temperature at the sensor location, and to avoid overheating the sensor should
therefore be installed at the point where the highest ambient temperature occurs.
Since the product is a heating system with a flexible range of application, all the relevant
Directives, rules and regulations need to be determined and complied with, including
monitoring of compliance. In addition, it is absolutely essential to observe the following
manufacturer's information (instructions for installation and operation). Before putting the
system into operation, please check which regulations or internal works rules are applicable
in your case to ensure safe and trouble-free use of the heated hose.
I.1. Installation / putting into operation
1. Check the data on the type plate to make sure that the type, design, mains voltage,
power and operating temperature correspond to your specifications. Check visually if the
hose design corresponds to the one ordered by you. If in doubt, compare with your
documentation. Does the heated hose meet the conditions for the intended application or is
it unsuitable for this purpose?
2. If you use clamps or similar fasteners for supporting the hose, it must be ensured that
pressing does not reduce the external diameter by more than 10 % at the most. Above this
10 % limit, there is a risk of damage to heat conductors, control leads and sensor wires.
3. If there are control cores running through the hose, please observe the electrical load
capability of these cores.
4. Please ensure that you are using the correct type of temperature controller. Controller
rating, sensor type and temperature range must be compatible. Is the heated hose
connected to the correct controller? An accidentally reversed sensor, for example, will result
in heating up the hose until it is completely destroyed. There will be no such problems if
you employ the available Winkler hose controller systems.
