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 fixed cycle of 6 hours (12 h total cycle
time). 1 load cycle corresponds to the change from the unpressurised
state to operating pressure.
When the pressure vessels are approved according to other
regulations, different load cycle calculations apply accordingly.
