Reliable alternators for demanding applications

Two new diesel-driven generator ranges launched

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.” Enquiries: +27 11 824 0410

Think Power Think Silicon Engineering

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.
