Recommendation:
In order to avoid dew, the temperature of the water inlet is greater or equal to the interior temperature of the
device. With other cooling water temperatures as mentioned above please contact Baumüller Nürnberg.

Notes referring to cold plate
Cold plate is an particularly efficient cooling version. Heat dissipation is made via two contact surfaces. One
is in the control cabinet as a mounting platform or at the machine base. The other one is a cold plate on the
rear of the unit. In order to have an optimum heat flow, there are high demands to this functional surface re-
ferring to the surface roughness and the evenness. A light damage of the surface can lead to a significant
deterioration of the heat dissipation to the mounting plate.
The sensitive functional surface therefore must be protected against damage when handling the parts.
BM3200/BM3300
1)
Air temperature in the entire suction area of the device.
2)
The cooling air requirement must at least accord to a free blowing process of a device. A free blowing process
means, that the air in- and output can take place unimpeded. At installation of the device into a control cab-
inet, it may be necessary, to insert additional fans, to cover the necessary cooling air requirement. If the nec-
essary cooling air requirement of the power heat sink is not provided, the output power of the device must be
reduced.
