Installation Instructions

5.9.1 Determining the size of the radiator
The size of the radiator must be dimensioned in accordance with the total thermal load, the operating conditions,
and the installation situation.
Note: In principle, the thermal load of the generator equals 1.8
times the electrical rated power (1.8 times with a water-
cooled silencer, 1.2 times with a dry silencer) in kW. This
means that e.g. a Panda 12000 PVMV-N generator with a
rated power of 10 kW has a thermal load of 18 kW.
Warning: Include safety margin in the calcula-
tion. The radiator must always be dimensioned taking into
account a safety margin adjusted for the operating
conditions. Undersized radiators will result in an
emergency shut-down. This may damage other
equipment that is connected to them.
5.9.2 Radiator design
The radiator consists in 3 main components:
1. Radiator. Depending on the version, includes an integrated expansion tank or an external expansion tank.
2. Fan. Depending on the generator, as a DC fan (e.g. 12 V-24 V) or as an AC fan (e.g. 230 V 50 Hz) with
respective input voltage.
3. Cover (optional).
5.9.3 Radiator types
In principle, the following radiator types are differentiated.
1. Flange-mounted radiator for installation on top of, on the side of, or under the vehicle - Siehe “Installation location
for radiators for roof, side, or underfloor mounting on the vehicle” auf Seite 57.
2. Built-in radiator for installation in the vehicle wall or cabin wall - Siehe “Installation location for radiator in the
vehicle wall or cabin wall” auf Seite 61.
3. Permanently installed radiators for the PVK-UK series
4. Permanently installed radiators for the PSC series for operation inside containers or for tunnel installation - Siehe
“Installation location for radiator in a tunnel” auf Seite 62.
The radiator must be installed away from the generator in a well ventilated area. In doing so, it must be ensured that
the air outflow of the radiator is completely uninhibited. Turbulence and thermal short-circuiting must be avoided.
The radiator can be installed in a vertical or a horizontal position. It must be taken into account that the air intake is
located above the fan motor.
The best results will be achieved if the radiator can be mounted horizontally on the vehicle roof.
