Refrigeration with many evaporation

DESCRIPTION

 

The refrigeration with many evaporation unit is delivered complete, instrumented with technical handbook and practical works.

Adapted to various levels and fields of studies.

Designing, manufacturing and industrial materials.

Utilisation of refrigerant R404A conforms to the new standards of the refrigerants.

Composed of a power station PECOMARK, two doubles flow evaporators placed in two isotherm boxes, a third evaporator is placed in the environment.
