We never expect our client to be the ventilation expert - that's our job. Knowing what we know, we will always take the initiative and strategically help the client cut energy costs in every stage of their ventilation, calculating and suggesting improvements for them where many other ventilation companies would just install their fans and leave it at that. That's probably why EOL Ventsystem - even though being a small firm - still remain the go-to choice for many large mining companies worldwide.
