that a tracked system is the best solution for
operation in high sea states, and continues
to work on enhancements to its well-known
RAST and ASIST systems. In the longer
term, the company is also working on what
Mr Brand described as an affordable, low cost
system intended for smaller platforms.

AUTOCHARGEAUTOMATED CYLINDER FILLING SYSTEMS
For Diving Air and Fire-Fighting Breathing Air Cylinder Charging On-board Ship
Imagine taking uncertainty out of an unfamiliar task, the end result of which may save lives. Filling breathing air cylinders is a time
consuming, manual process, not without risk and often with a variable outcome in terms of the mass of gas ﬁ lled... Until now
Applied industrial control and sensor technology – allows: Track record – proven technology:

Repeatable, maximised & consistent mass of gas ﬁ lled >1,000,000 hours in-service

Cylinder ﬁ lling times as fast as 90 seconds Proven in complex industrial applications

Temperature effects to be fully controlled
Fitted to UK’s Helicopter Carrier HMS Ocean

Different pressures for different applications e.g.
Supplied for all 6 of UK’s latest T45 Destroyers
300 bar for breathing air
Speciﬁ ed on UK’s next generation Aircraft Carriers
200 bar for diving air

60 years experience in breathing & diving air systems
Multiple cylinder ﬁ lling from one panel

Guaranteed through-life support
Cylinder ﬁ lling from any residual pressure e.g.
0 to 380 bar (5,510 psi)
Simple, yet robust design:

Control of breathing air quality to recognised standards

Push button operation to start, stop and vent down
Real time on-line monitoring option
Clear indication of ﬁ lling in progress
Automation – means:
Emergency stop

Ease of operation
Shock & vibration tested

Risks inherent with manual control are removed
Constructed in materials to withstand marine environment

Safe control of high pressure air
Modular design to ﬁ t in to any available space

Reduces the need for skilled operatives
Modular design allows single or multiple ﬁ lling outlets

Reduced training requirement

Less time is spent ﬁ lling and re-ﬁ lling cylinders

More time to do other jobs while cylinders ﬁ ll
