Material Used as Description
PVC Pipes, valves, t‐
tings and hoses
Use is not permitted.
Hoses Reduce the use of hoses to a minimum (device connection). Must
not be used as the main pipe for the whole system. Recommenda‐
tion: EPDM hoses with an electrical resistance>10
9
Ω (e.g. Sem‐
perex FKD supplied from Semperit or DEMITTEL; from PE/EPD,
supplied from Telle).
Gaskets Pipes, valves and
ttings
Use of Viton, AFM34, EPDM is recommended.
Hose connections Transition
Hose-pipe
Secure with clips conforming to DIN 2817, available e.g. from the
Telle company.
The following recommendation applies in order to achieve an optimum motor heatsink
(enclosure) lifetime:
• Engineer a closed cooling circuit with cooling unit manufactured out of stainless steel that
dissipates the heat through a water-water heat exchanger.
• All other components such as cooling circuit cables and ttings manufactured out of ABS,
stainless steel or general construction steel.

Note
Other manufacturers
You can also use equivalent products from other manufacturers.
Responsibility for the properties of third-party products resides with the plant manufacturer.
Consider the following pressure conditions when designing the cooling circuit.
Permissible pressure
• Dene the working pressure based on the ow conditions in the supply and return pipes of
the cooling circuit.
