may be necessary should the warm air need to be channelled through pipes.
It must be ensured that warm air is extracted out of the radiator.
6.8.5 Permitted coolant temperatures
The performance of the radiator must be so measured that the coolant temperature of the Panda generator does not
exceed more than 70°C. The coolant intake must be fitted direct to the coolant pump.
There must be a large amount of water circulating to ensure that the difference in temperature when compared to
the temperature of the water leaving the generator (full load) does not exceed 12°C. The difference may also
amount to 17K if a pre-silencer is installed.
The hoses must be so laid out that knots and other obstructions are avoided. If necessary, the amount of coolant
must be measured. As a minimum the following values are necessary:
6.8.6 Essential coolant amounts:
Panda 4500 ............................... min. ca. 10 l/min
Panda 8000 - 9000 ...................approx. 16 to 22 l/min
Panda 12000 - 14000 ..............approx. 24 to 28 l/min
Panda 18 - 24 ........................... approx. 32 to 38 l/min
Panda 30 - 32 ........................... approx. 40 to 45 l/min
Panda 42 - 65 ........................... approx. 50 to 60 l/min
The greater the amount of coolant circulating, the lower the difference in temperature. If the necessary cooling per-
formance cannot be achieved, the amount circulating can be increased by adjusting the pulley on the pump and
thereby raising the performance.
ATTENTION! The coolant pressure may, however, not exceed 0.7 bar!
6.8.7 Construction and position of the radiator
The radiator can be assembled away from the generator in a well ventilated position. Attention must be paid that the
radiator emission direction is completely free of obstruction. Turbulence is to be avoided. There is often a clash
between the streamline appearance of the chassis and the technical requirements.
The radiator can be installed (vertically) or (horizontally). Consideration must be given to the fact that air is drawn in
via a fan motor.
The best result is achieved if the radiator is fitted vertically on the vehicle roof.
