WVM 45 -1450

Note on load cycle calculation:

According to the EC pressure equipment directive the dryers are rated for

14,000 load cycles. This corresponds to a service life of approx. 20 years when

operated in the ﬁ xed cycle of 6 hours (12 h total cycle time). 1 load cycle corre-

sponds to the change from the unpressurised state to operating pressure.

When the pressure vessels are approved according to other regulations, these

cyclic loading calculations may not be valid.
