The sensible solution

Situated in the Gerland-District Technopole in the southern part of Lyon, an area that is oriented towards high technology industries, Ecole Normale Supérieure de Lyon (ENS Lyon) is one of the topscientific “ Grandes Ecoles “ in France.
Based on a site of 8 hectares the school in addition to teaching facilities also includes a library, a restaurant and residences. In all it amounts to 37,000 square meters. The school required applications for heating, ventilation and air conditioning of the buildings mentioned. Due to the need of water distribution with variable flow and temperature Grundfos choose to install In-Line pumps.
 

Grundfos In-Line pumps feature high-quality cast iron surfaces that are cataphoretically treated to make them significantly smoother. This reduces friction and improves the efficiency of the pump. For the school this meant a solution that generated less heat and thereby reduced the requirements to cooling. As a benefit the lower operating temperatures prolong the service life of the motor bearings and the motor requires less frequent lubrication. This saves both time and money on the school maintenance budget.

Due to close cooperation the technical installation work was carried out at virtually the same time in all the four sections of the school. It was therefore important that the contractor responsible for all the technical fittings could rely completely on its suppliers to deliver.
