Different models for roof mount, side mount or underfloor mount are
available.
The cooling capacity must be selected regarding the generator size and the
operation area (f.e. radiator with higher capacity for operation in warm areas)

6.8.3 Determing the size of the radiator
Consideration must be paid to the total heat load when determining the size of the unit. This equates to the genera-
tor nominal performance without the water-cooled pre-silencer. The heat resistance is 1.8 times the generator nomi-
nal capacity, when the water-cooled pre-silencer is used (i.e. Panda 12000 PVMV-N has a total heat capacity of
approx. 18kW). The radiator can be serviced by any usual radiator servicing agency. It should, however, be pointed
out that the radiator possesses high safety levels. The radiator is often manufactured too small. Fischer Panda also
has various radiators available (for horizontal and vertical installation) as standard generator components.
6.8.4 Radiator position
The place and fitting position of the radiator must be carefully considered. It is especially important that the warm air
can escape. For this reason, the best place for the radiator is in a vertical position on the vehicle roof (if one take into
account that an obstruction could arise in narrow entrances).
The manufacturer is only too happy to give suggestions on how to install the radiator. It must, however, be expres-
sively pointed out that all recommendations of this type are not binding. It continually occurs that special influencing
factors are not recognised from the start. The customer or the technician making the installation must always take
changes to the position or radiator’s place of installation into consideration. The manufacturer cannot accept liability
for the recommendations given to the best of his knowledge. As a precaution, attention should always be paid that
the air outlet for escaping warm is as large as possible. The vehicle paint sprayer is often not in agreement with
this, but the person making the installation must make the aim clear. The fitter must make his position clear.
Radiators which are installed vertically, and the warm air is blown downwards, must be twice the size of such radia-
tors, by which the warm air rises through its own thermal energy. It must also be considered that a build up of heat
results through the emission of warm air in the direction of the ground, whereby the warm air is once again forced to
rise to the area of the radiator. Freely escaping warm air cannot be guaranteed in this case. Additional ventilators
