2 TEChNICAL DESCRIpTION
The Divator Lite cylinders are manufactured with full composite materials. A carbon fibre filament
and an outer wrap of glass fibres covers a thermoplastic liner. An epoxy resin reinforces the
carbon and glass fibres. The end fittings are made of acid-proof stainless steel.
The working pressure is 300 bar with a test pressure of 450 bar. The minimum burst pressure of
the Divator Lite cylinders is 900 bar. The cylinders have a Non-Limited Life (NLL) approval.
The cylinder valve has a burst disc to avoid overpressure. The burst disc is designed to open if the
pressure exceeds 450 bar. If the burst disc is released it cannot be reused, it must be replaced at
a service centre.
3 ChARGING Of CYLINDERS

in a audible crackling sound. This is perfectly normal and no action is required.
