Electrical switching & drive systems & components
Vert Energy is the sole distributors for Leroy-Somer in southern Africa and supplies and supports the entire LS range, which includes standard and adapted AC and DC motors, geared and brake motors, variable speed drives and alternators.
“Leroy-Somer’s motor, drive and automation solutions focus on maximising energy savings, enhancing performance and safety and optimising productivity in diverse sectors,” says Vert Energy managing director, Grant Robertson. Included in the LS range are LS ATEX induction motors designed for safe use in hazardous areas, including gas zones 1 and 2 and dust zones 21 and 22.
These multi-purpose fixed and variable speed-compatible motors, which comply with stringent quality and safety specifications for operation in explosive, gas and dust atmospheres, provide the highest guarantees of safety and reliability in extreme conditions. Further advantages are energy efficiency, reduced CO2 emissions and short-term return on investment.
The ATEX motors can be adapted to several configuration variants and finishes to meet exact requirements of the manufacturing or automation application, with variable load factor limitations, extreme operating cycles or the need to increase productivity. This range is particularly well suited for pump, ventilation, agitator and mixer applications in refineries, pipelines, petrochemical and food industries.
LS ATEX motors meet IE2 high efficiency and IE3 premium levels as standard in 2,4 or 6 poles and frequencies of 50 Hz or 60 Hz. Frame sizes range from 80 to 355 and power ratings are between 0,75 and 400 kW. Ratios between rated power, speed and frame size for LS ATEX motors comply with the applicable standards IEC 60034 and 60072.
Apart from the online Leroy-Somer ATEX technical catalogue, which comprises critical information on efficiency and mechanical/electrical data, the company also has an online configurator to assist in the selection of motors, brake motors or geared motors, combined with variable speed drives.
Vert Energy’s service encompasses the supply of quality branded products that combine high performance, energy efficiency, reduced downtime and extended service life, to meet the highest performance, safety and environmental standards. Factory and OEM trained technicians assist with any electromechanical breakdown situation or routine preventative maintenance procedures throughout Africa.
Vert Energy is also the authorised sales and support partner for DEIF generator controls, API/Covrad GT Heat Transfer, ASCO automatic transfer switches and Avtron and Froment load banks, as well as Allight Lighting towers.
