Gas Cooler:

The gas cooler's reason is to erase the heat of compression from the procedure gas that has just been discharged from a compressor.  Certain category of levels uses a gas cooler hold inside the converter as display on Figure.  The gas coolers might be separate units placed among the compressors and the converters.

Barrier Tubing

In the previous stages of converter design, it was recognized in which barriers made within the form of flat sheets and stacked inside a container would offer the most barrier area per unit volume.  For practical purpose, the barrier had to be made in the form of tubes. More engineering knowledge was available for tubular construction and the urgency of the problem did not permit any not essential development time. The use of tubes also permitted more satisfactory replacement of damaged barrier material. Conclude, the barrier is made in the form of thin-walled tubes.
