EC20 in HDR: aircompressors

These are the three aircompressors of unit EC 20; they provide instrument air and air for air driven tools (grinding tools and so on)
The air is stored in 3 large vessels; one can be seen in the background (the green thing).
In the background you can also see the lower side of the boiler which is hanging free, it expands about 20 centimeters down when it's filled with water up to normal level.

On this picture you can see from where I took this picture.

Special day today... it's my birthday; celebrating while on duty.
