Conversion of a refrigerant at Entremont
Juragruyère, a producer of the 'Comté' cheese (at Entremont in Franche-Comté, France), retained Boost'air - industrial and commercial refrigeration specialists - and Climalife, for the replacement of the R-22 refrigerant with ISCEON® MO59 (R-417A).
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.
After more than one and half years in service, the R-417A proved its efficiency by being able to maintain a controlled atmosphere in the conditioning and packaging roomspace of the 'Comté' cheese at the Juragruyère Cheese Dairy.
The reconversion of other installations on the site is planned to reduce to a minimum production stops and to comply with European Regulation 2037/2000 concerning R-22.
