OLAER (Switzerland) AG was founded in 1969 in Colombes (F) by Manfred Steiner as a fiduciary of OLAER Industries SA. It was in 1976 that we were able to move to the facilities where we are currently located, in Dudingen (in the Canton of Fribourg). In 1990 this building was expanded for the first time and in 2006 one floor was added to it.

On the 1st of July 2012 the worldwide active OLAER Group was taken over by Parker Hannifin Cleveland.
On the 1st of January 2013 OLAER (Schweiz) AG was bought back by its management and became a certified Parker distributor for hydraulics.

Since being founded OLAER quality assurance has been part of our company philosophy. The company became ISO 9001 certified in 1995.


Since its establishment, OLAER (Switzerland) AG has been active in the engineering, sales and maintenance of products and systems for the storage, cooling and filtration of liquids.

In addition to the hydraulic accumulators, heat exchangers and hydraulic filters we have specialised in calculation of pressure surges (water hammer) and the supply of corresponding dampers for drinking and waste water systems.
