S.COLI - DEC MVD COOLING SYSTEM– PATCHPANELS PP1: TRANSITION (FLEX-METAL TUBES) PP2: FOR ASSEMBLY PP3: FINAL PP4: PRESSURE SENSORS AND FITTINGS, AFTER CAL INSERTION PATH ? BEFORE CAL INSERTION

S.COLI - DEC MVD COOLING SYSTEM– REQUEST 1 THE RETURN TUBES AT THE HEIGHT OF THE FLOOR? CROSSING PROBLEM?

S.COLI - DEC MVD COOLING SYSTEM– REQUEST 2 CAN THE MVD OCCUPY THE RIGHT SIDE OF THE PIT? CROSSING PROBLEM? AVAILABLE AREA?

S.COLI - DEC MVD COOLING SYSTEM – QUESTIONS Can the return tube be located on the floor along the external wall? Can the MVD cooling plant occupy the right side of the pit ? From where does the cold water arrive? AIR line at 6 bar? Where? Is the door a passage? Can we put the patch panels? The small patch panel4 on the floor held by the CAL support (charriot)? After CAL insertion, we need to cut tubes to patch panel 4 (?) The path for the flex tubes from PP3 to PP4?
