“With existing supply agreements with Anglo American Platinum and Impala Platinum, we’re thrilled to extend our market share in the platinum industry through this new agreement with Lonmin,” Louis Kotze, Zest WEG Group’s area manager responsible for Rustenburg says. “Zest WEG’s Rustenburg branch is now party to formal supply agreements with all three major world platinum producers.”
He explains that Lonmin Platinum was seeking to enter into an agreement that offered a low voltage motor standardisation supply strategy for IE2 (Premium Efficiency Plus) motors that would cover a complete range of low voltage cast iron electric motors, ranging from 0.18 kW to 330 kW.
“The new IE2 WEG motor efficiency specification will allow Lonmin Platinum to meet its medium term low voltage electric motor energy saving objectives. Zest WEG is well known for its proven Total Cost of Ownership (TCO) programme on low voltage motors and we believe a key motivation for Lonmin Platinum to enter into this landmark supply agreement with Zest WEG was the prospective long term benefit.”
As part of the support functions while the agreement was being implemented, Zest WEG assisted with motor repair specifications that allowed Lonmin Platinum to receive back repaired electric motors as close as possible to the WEG OEM specification from repair companies. Zest WEG also assisted with technical motor data details in order to streamline the SAP coding and commercial order process.
The supply to the Mardin plant is highlighted by three 1200 RPM motors, with output ratings from 2100 to 2600 kW at 6.3 kV. Also supplied are 30 low voltage motors from 400 to 690V. All of the supplied Variable Frequency Drives contain the POROFIBUS-DP communication interface and have outputs from 2.2 to 1120 KW. Of the VFD's to be delivered, eight units have been pre-assembled inside WEG panels, the remaining units will be integrated to the system control panels by Dal Elekrik in Turkey. Mardin cement produces over 700 thousand tons of clinker and over 1 million tons of cement per year. The company is owned by the OYAK group, which is the market leader in this segment with 6 factories and 2 beneficiary plants. In addition to cement, the group, headquartered in Ankara, has investments in 26 companies including holdings in the automotive, chemical, food and service segments.
