Product News Monday, October 18, 2010: Diesel Electric Services (Pty) Ltd

Diesel Electric Services (Pty) LTD leads the way in the power generation market by supplying; installing and commissioning the new gas powered generating sets for the MTN tri-generation plant in Fairlands.
This type of reciprocating plant is the first in Sub-Saharan Africa, and promises up to 85% electrical/thermal efficiency on fuel using the tri-generation concept, supplying combined heat, cooling and power generated by the two 1MW natural gas powered generating sets. Achieving approximately 40% efficiency for electricity generation on the methane rich natural gas, the waste exhaust gas energy is transferred to water via a heat exchanger and then through lithium bromide absorption chillers providing the chilled water to the air-handling units which in turn supply the cool air for the IT equipment, totaling up to the 85% electrical/thermal efficiency on fuel.  Hot water is also sent via a second pass heat exchanger to provide general hot water for the remainder of the building. Coupled with electricity price increases, MTN expect to get a return on their R 22Million investment within 5 years. An important addition is that MTN have been able to register this project with the United Nations as a carbon credit project, assisting in offsetting the capital costs.

Diesel Electric Services ( DES ) has also recently completed another first in this field, supplying and installing 4 x 2.9MW Natural gas powered gensets operating in parallel in a Co- generation project for a large financial concern in Central JHB. These generating sets operate at 11kV.

We have been involved in gas powered generation for many years, one of which includes the first
“ Producer Gas “ project in conjunction with Eskom using gas from the combustion of dry wood to provide fuel for a gas powered generator, aimed to provide electricity in remote rural areas using plants such as “invader bush” as a primary source of fuel.

12 years ago, we manufactured, supplied and installed 3 sites in Mozambique with Natural Gas powered Gensets, establishing DES in the gas generation market.
