For the removal of the existing plant to the current site of Juragruyère at Poligny, Department of the Jura, France, the R-417A refrigerant was selected for its simplicity of implementation, because of the possibility of retaining existing equipment and for avoiding numerous modifications.
The cooling circuit with glycol based Friogel®, of an 85 KW refrigerating power rating similar to the R-22, could not be removed to the new site unless an HFC type refrigerant was used.
The conversion of other installations on the site is planned to reduce production stops to a minimum and to comply with European Regulation 1005/2009 concerning R-22.
