A stationary reduction apparatus is arranged so that coil groups comprising plate type (or disc type) coils, which are stacked up in multiple layers with spacers inserted therebetween to traverse through a core whereby a refrigerant may pass through inter-layer clearances, are provided and divided into a plurality of coil sub-groups and every other coil sub-group of the divided coil sub-groups is surrounded by a refrigerant guide which is provided with an opening on its internal periphery and refrigerant flow ports on its external periphery, and the refrigerant is introduced into the refrigerant guide to flow in a horizontal direction through respective inter-layer clearances of the stacked-up coil groups, thereby the coil groups are effectively cooled without accelerating the velocity of refrigerant flow.
