Indeed only two other C175 units have been
installed in Southern Africa in standby gener-
ating applications, and they have proved to be
highly successful so far,” Richardt points out.
“The C175 engine represents cutting edge
technology in terms of engine size relative to
power output and fuel efficiency.”
Barloworld Power tendered to Barloworld
Equipment Namibia for the supply of the moti-
vators and the tender was accepted by Swakop
Uranium as part of the total package including

requirement to start up a
Cat 7495 rope shovel is more
than 4 000 kVA, requiring
two motivators running

mounted separately on the gooseneck.
