Renttech South Africa has recently launched two new ranges of diesel-driven
generators, which include a heavy-duty range covering 10 to 30 kVA in single-
and three-phase sound-attenuated models, and an extra heavy duty ‘rental spec’
series for extreme conditions. “The smaller units are popular for domestic and
small business use, whereas our standard units are popular with larger businesses
and site use. The ‘Rental spec’ units are aimed at heavy-duty on-site applica-
tions,” explains Martiens Opperman, Renttech South Africa’s operations manager.
“The 10 – 30 kVA range is small and compact, 1 500 rpm, sound-attenuated and
fitted with a Kubota/Newage Stamford power pack,” he explains “The heavy-duty
‘Rental spec’ units can be double-stacked, painted to marine container specifica-
tions and can be supplied as duel frequency units (50 / 60 Hz) fitted with either
Perkins/Newage Stamford or Cummins/Newage Stamford power packs.”

Two new diesel-driven generator
ranges launched
VERT Energy has extended its range of electric power
generation (EPG) components tomeet growing
demand fromgenerator set builders and electro-
mechanical power transmission industries.
“Increasing energy requirements have placed
power utilities under enormous pressure throughout
the African continent, which is why companies are
investing in alternative sources of electricity produc-
tion,”says Vert Energy’s managing director, Grant
Robertson.“Vert Energy has established turnkey
solutions partnerships in diverse sectors, including
mining, shipping, agriculture, general engineering,
shipping, the railways, gas and petrochemicals.
“Through an extensive range of quality branded
EPG products and a highly skilled teamof technical
experts, the company plays amajor role in providing
dependable power to companies, even in Africa’s
most remote regions.
“As part of our commitment to the genset
manufacturing sector, for the swift supply of reliable
components, Vert Energy has made a substantial
investment in sourcing the finest components that
produce electric energy frommechanical energy and
which withstand harsh operating conditions.
“The company has been appointed exclusive
distributors in sub-Saharan Africa for leading power
generation brands, complemented by genuine spare
parts and accessories. EPG components include
Leroy Somer alternators, DEIF generator controls and
Covrad heat exchangers.
“A critical part of our service is the availability
throughout Africa of factory and OEM trained techni-
cians who cope efficiently with any electro-mechan-
ical breakdown situation or routine preventative
maintenance procedures.”
Leroy Somer, the largest producer of alternators for
gensets globally, provides clean energy solutions. LS
alternators, with ratings in excess of 20 000 kW, are
suitable for all drive systems – whether for supply-
ing electrical power on board a ship, electricity to
deprived regions, or for preventing interruptions in
themains supply.
LS alternators, which are known for ease of
integration and enhanced energy savings, are also
recognised for high performance and reliability in de-
manding applications and harsh environments.
Themodular design of these alternators means
that the basic universal unit can be adapted to suit
anymake of primemover.
The LS industrial range of low andmediumvoltage
alternators (50 and 60 Hz, 4 and six-pole, from10
kW to 3 900 kW) are designed for gensets driven by
diesel or gas engines.
The AREP excitation system is a brushless, self-ex-
cited systemknown for its efficient performance and
enhanced safety. It enables a short circuit current of
about three times the rated current to bemaintained
for 10 seconds. This means that a circuit breaker can
be tripped if there is a fault, without disturbing other
loads supplied by the alternator.
Customised high, mediumand low voltage LS
alternators (50 or 60 Hz, 4 – 24-pole, from500 kW to
25 000 kW) are driven by diesel or gas engines, or by
gas, steam, wind or hydro turbines.
Also in the LS range are alternators designed for
specialised applications, for example, in agriculture.
The robust Tractelec is a generator driven by a
tractor’s power take-off shaft, providing an alterna-
tive source of energy production. This three-phase
Partner alternator, which operates efficiently in
demanding farming environments, is coupled to a
gearbox with oil cooled lubrication and an electrical
protection and distribution box.
