Planning details

▪

Fresh and ventilation in the ceiling area, exhaust in the floor area

▪

The ideal position is determined by the position of the air conditioning system connections.
Air ducts should not blow directly on to the magnet.

▪

The filter plate for the fresh air supply is assembled in an installation frame or directly
screwed to the cage.

6.3

Exhaust system

The magnet may only be installed or operated with a

gas extraction system for cryogenic

gases (quench pipe)

. In the case of a quench, large volumes of cryogenic gases are safely re-

moved outside using the gas extraction system.

If a magnet with a nitrogen tank is used, the installation of an additional room ventilation open-
ing in a bottom position is recommended.

WARNING

Warning of injury by cryogenic gases

The gas extraction's outlet to the outdoors must be designed in such a way that no one is able
to come into contact with cold gases.
