Oil cooler : Shell and tube heat exchangers

Rotating machines not only require proper lubrication, but also heat dissipation from their operation. Shell and tube oil coolers make it possible on the one hand to cool and therefore extract part of the heat produced during the operation of the rotating machine, but also to restore to the oil its viscosity properties and therefore its power.

OIL COOLER – THERMAL SPECIFICITIES:

Quiri, specialist in shell and tube heat exchangers, introduces you a BEU TEMA type oil cooler.

We have delivered this type of heat exchangers for oil cooling to Finland, France and China as part of the construction of EPR type nuclear power plants.

The industrial 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).

GEOMETRIC SPECIFICITIES:

Vertical tubular heat exchanger, overall length 3.5 m, empty weight 2 tons.

CONSTRUCTION SPECIFICITIES:

Code : EN 13445

Calculation of the heat exchanger by finite element. The heat exchanger shell and tube oil cooler 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.
