Description
1
The dryers can contain pressurized air. This can be potentially dangerous if the equipment
is misused.
2
The towers of the dryer consist of an extruded profile, which must only be used as a
compressed air vessel and must be operated within the limits specified. See section
, table A.
3
No alterations must be made to the vessels by welding, drilling or other mechanical
methods without the written permission of the manufacturer.
4
The design pressure and temperature of this pressure bearing part must be clearly
indicated on the data label.
5
If installed, the safety valve must correspond with pressure surges of 1.1 times the
maximum allowable operating pressure. This should guarantee that the pressure will not
permanently exceed the maximum allowable operating pressure of the vessel.
6
Original bolts have to be used after opening for inspection. The maximum torque has to
be taken into consideration (see table below).
