Local context

Working in Stellenbosch Techno Park

We service Stellenbosch Techno Park and the surrounding blocks of Stellenbosch Techno Park, Stellenbosch, with access off the R44 and R310. Mediterranean summers with strong south-easters carry dust and salt onto condenser coils, and winter rain drives condensation risk at dock openings.
