Sustainability & environmental protection

Sensitive injection systems are the result of ongoing optimisation of engine technology and increased limits on climate-relevant gases in accordance with the Tier III standard. To ensure their functionality, a fuel that is virtually free of contamination particles is required. If this is not the case, the system will suffer. As your local experts, HYDAC has filtration concepts for every application. We sustainably reduce your costs thanks to longer filter service lives and a higher level of cleanliness.
