Thermal specificities:
Quiri, specialist in heat exchangers, introduces you a BEU TEMA type oil cooler.
We have delivered this type of heat exchangers to Finland, France and China as part of the construction of EPR type nuclear power plants.
The oil cooler, which is a multitubular heat exchanger, of Quiri thermal design, provides cooling of the upper bearing oil of each motor (primary fluid) by heat exchange with circulating demineralized water (secondary fluid).

Construction Specificities:
Code : EN 13445
Calculation of the exchanger by finite element. The heat exchanger is designed to withstand the seismic forces generated by horizontal and vertical accelerations as well as to withstand the seismic forces exerted in the event of primary piping failure.
Regulation: DESP 2014/68 / EU
Calcul de l’échangeur par éléments finis. L’échangeur de chaleur est conçu pour supporter les efforts sismiques engendrés par les accélérations horizontales et verticales ainsi que pour supporter les efforts sismiques exercés en cas de rupture de tuyauterie primaire.
Règlementation : PED 2014/68/UE
