Micafluid Company Profile

Competence and Experience

Micafluid AG, Switzerland was found in 2005 and has taken over the oil treatment and regeneration business

from ABB Switzerland Micafil, the official signing date was on 28th Feb 2006.

Since 1st of March 2006 MICAFLUID Ltd has started its operation in the new location in Zurich, Schlieren.

Through the nearby situated airport and logistical centres, our worldwide presence is assured and our

procurement times can be kept at a minimum.

Furthermore, Micafluid is working together with the partner company Ekofluid Bratislava. In cooperation with

Ekofluid we are also able to offer regeneration units with automatic reactivation of Fullers Earth.

University connections and collaboration with research centres permit us to continuously expand fundamental

understandings.

To identify trends, technical data are collected from the past and presence. This allows Micafluid to offer

competent services for our products. Annual training programs for our staff increase the level of competence

and teamwork among our staff.
