Watercooling

Tecnotion TL and TBW series iron core motors come equipped with wa-
ter cooling capabilities. The continuous force water cooled specifications
for the TL and TBW series are based on pure water cooling. This chapter
explains how to design your water cooling system with water and other
common coolants.
Further information regarding the location and dimension of the
water cooling connections can be found in chapter
connections on page 16.
Connection of hoses
When fitting the hoses, the connections have to be free of greases and oil.
The two cooling channels of the TL-motor can be connected in series. Both
cooling channels can also be used in parallel configuration. This connecti-
on reduces the pressure drop, but only if cavitation is less ø6mm-ø8mm,
when using Y-joints.
