Electrical equipment and industrial instrumentation supplier Magnet Group has completed a lighting upgrade project for paint manufacturer Dulux to reduce the energy consumption, load and associated costs of its Umbogintwini plant, in KwaZulu-Natal.
“Phase 1 of this project involved the design and installation of a new energy efficient lighting system to deliver electrical performance and energy savings within 10% of predictions.
“In some cases, calculations of savings have been exceeded,” says Magnet MD Brian Howarth.
The installation, which entailed replacement, retrofitting and relamping of the lighting systems, has met the key objectives of enhanced safety, timeous installation, high-quality fittings and cost efficiency.
“A 47.3% decrease in kilowatts, as well as a 50.4% decrease in kilowatt hours, enabled the estimated savings to be achieved,” says Howard.
Operations included the replacement and upgrade of lighting in certain areas of the engineering workshop, the raw- material stores, the packaging stores, the filling hall, the holding area and the national warehouse.
As a pilot initiative, occupancy sensors and day-night sensors have been installed in the aisles of the raw-material stores and in the bulk bag area to control the activation of thirty 1 × 58 W lights.
Occupancy sensors were also installed in the holding area.
New fluorescent fittings by Magnet replaced high-pressure sodium lamps in the national warehouse. This has resulted in an improved colour rendition index and lower maintenance requirements.
These fittings have a three-year service life, compared with about 18 months of service from the previous light fittings.
Meanwhile, Magnet, in partnership with Energywise, a New Zealand-based programme that provides information and funding for households regarding energy efficiency, energy conservation and renewable energy, has been contracted by State-owned power utility Eskom to assemble, distribute and install new energy- saving showerheads to organisations with multiple shower facilities, at no cost to approved applicants.
This joint venture has enabled members of the KwaZulu-Natal Society for the Blind to save energy through the use of energy- saving showerheads and water restrictors for taps.
The initiative is also creating employment opportunities.
