The Hoffmann La Roche in Germany systematically approached the modernisation of its compressed air supply. After it was detected that the existing compressed air station caused high operating costs and substantial maintenance costs, Hoffmann La Roche firstly had to seek a competent service partner, which could carry out a current status analysis and develop an appropriate solution concept.
This partner was found in Donaldson. As a leading manufacturer of components and systems for compressed air processing, Donaldson knows the quality and efficiency requirements, which the pharmaceutical production sets the compressed air supply. Donaldson is a multi-supplier with regard to compressed air supply - thus best prerequisites for an objective consultation.
Donaldson experts determined the pressure and flow rate requirements of production and further quality relevant parameters (compressed air temperature, residual oil content) by means of an online measurement conducted over several weeks. The result of the measurement analysis showed that there were indeed large savings potentials - for example the minimisation of compressor stand-still times, reducing of the compression and pressure and exchanging older adsorptions dryers.
On the basis of these results, Hoffmann La Roche and Donaldson compiled a contract specification for the modernisation, which amongst other things included the extension of the compressed air station with a speed adjusted compressor, a superior intelligent learning control system as well as 100% redundant compressed air processing.
Out of the four contractors participating in the bidding procedure Donaldson was able to obtain the business. Harald Kassner, purchasing manager of Hoffmann La Roche, reported, "apart from all technical aspects Donaldson could definitely offer us the best cost-performance ratio.”
In order to accomplish the modernisation without interrupting the compressed air supply, the work was completed in three partial stages. In doing so, the extensive conditions in the Good Manufacturing Practice documentation were fulfilled. The training of the service personnel was likewise part of the service offering, which in the course of the modernisation at Hoffmann La Roche, was performed by Donaldson.
On completion of the work, Hoffmann La Roche drew a completely positive result. Project manager Stephan Schnath stated, "the modernised compressed air station runs trouble-free; we are absolutely satisfied with the work performed by Donaldson." And so that these conditions prevail, in the context of a servicing contract, the Donaldson service takes care of the compressed air supply and processing in the Hoffmann La Roche plant.
