Steam is distributed at 6 barg in a DN65 pipe. As steam velocity should not exceed 30 m/s in the

pipe, the maximum steam flow you could sent safely to Tunnel 1&2 is 1220 kg/hr.

Currently it is not a problem as your real steam consumption for these areas is lower. However, if for

some reason the steam demand is increased you have to be aware of this limit.

7.3 Steam users

Main steam users are the GLATT systems and the dehumidifier Munters which need hot air.

The factory use 8 GLATT and 9 Munters in the whole site.

-GLATT systems (for coating machines and fluid bed dryers)

Each air handling unit is equipped with 2 or 3 steam coils.
