FAQ
Questions we hear often
If your question is not here, send it through the contact form and we will answer directly.
How quickly can you respond?
Remote diagnostics typically begin within 24 hours of your request. On-site mobilization across Africa usually takes 2–5 days depending on location and visas.
Do you work on-site or remotely?
Both. Many PROFIBUS/PROFINET and network issues can be diagnosed remotely with your team on site; commissioning and audits are done on-site. We recommend the right mix per engagement.
Which sectors do you serve?
Mining, energy, oil & gas, manufacturing, water and utilities. We work anywhere reliable automation matters.
Do you sign NDAs?
Yes. We routinely work under mutual NDAs and treat all client information as confidential — including the existence of engagements where requested.
Are you a reseller for any vendor?
No. We are vendor-neutral. We are fluent in Siemens, Rockwell, Schneider, ABB and others, but our recommendations follow your needs, not supplier incentives.
How is pricing structured?
Every project is quoted on demand after we understand the scope. We offer diagnostic audits, full engineering & commissioning, and ongoing support retainers. Use the Request a Quote wizard for a tailored proposal.
