Equation 1
In order to account for thermal variations (like ambient temperature, closed chemical cabinets or
corners without ventilations) and to not significantly reduce the MTBF of the motor it is recommended to
keep about 20°C safety margin to the absolute thermal limit of the motor (90°C) when designing the
thermal concept of the pump system.
3.4.2 Controller Temperature
Depending on the ambient temperature and the placement of the controller, additional cooling may be
required (see Figure 19). To improve cooling of the controller, place the device into a moving air
stream. If the controller is mounted in a compact area or adjacent to additional heat sources (e.g. a 2
nd
controller), ensure that there is sufficient ventilation.
Figure 19 - Temperature Curves of Controller vs. Flow and Speed
The above curves are measurements of the controller temperature at 25°C ambient. Equation 2 shows
how to calculate the controller temperature for other ambient temperatures based on this curve.
