LED lighting for GIZ energy efficiency projects

EKA Schréder is proud to be part of an Energy Efficient Street Lighting Retrofit Project

Western Cape site houses two injector cyclotrons - one providing
intense beams of light ions and the other, beams of polarised
light ions or heavy ions - and a 6 MV Van de Graaff electrostatic
accelerator.
This highly specialised equipment is used for the treatment of
cancers and the production of unique radioisotopes. The facility
requires a continuous, steady and reliable source of electricity to
operate its accelerators and other sensitive scientific equipment.
The BAE batteries which provide backup power have been in
place at the Western Cape site for over seven years now with only
one cell damaged in all this time, no acid leaks and over 1,2 km of
