Cooling systems

The KEB COMBIVERT F5/F6 is available for different cooling systems:
Heat sink with cooling fan (mounted version)
The standard version is delivered with heat sink and cooling fan.
Special versions
The dissipation of power loss must be guaranteed by the machine builder.
Flat rear
There is no heat sink at this version. The unit must be mounted on an appropriate ground for
heat dissipation.
Water cooling
This version is dimensioned for the connection to an available cooling system. The dissipa-
tion of the power loss must be ensured by the machine builder. In order to avoid moisture
condensation, the minimum inlet temperature may not decrease the ambient temperature.
The max. inlet temperature may not exceed 40°C. No aggressive coolant shall be used.
Measures against contamination and calcination must be done externally. We recommend a
pressure of 4 bar on the cooling system.
Convection (trough-mount version)
In this version the heat sink is placed externally with a cutout in the control cabinet.

machine.
