I found the course really useful for my role in a data‑centre ops team. It broke down the complex stuff about continuous cooling tower cycles into easy‑to‑follow sections. I learned how to carry out a quick water‑chemistry check and even did a mock refurbishment plan that I can now use with my team. The videos were clear and the downloadable PDFs were spot‑on. It wasn’t perfect – I’d have liked a bit more on the latest eco‑friendly refrigerants – but overall I’m happy with what I got and feel more confident on the floor.
