Company information
Divex are world leaders in the
supply and manufacture of diving and subsea equipment for commercial,
professional, military and recreational divers. Through strategic acquisitions
and growth Divex has expanded to address the growing demands of the present
subsea market.
Although established as Gas
Services Offshore Limited in 1980 with its specialist Diver Helium Gas Recovery
System, Divex can trace its pedigree back to 1790 as Barry, Henry and Cook, an
Aberdeen based iron foundry with its engineering works in Loch Street, Aberdeen.
Through acquisition and merger. Divex now combines some of the best known names
in the underwater industry such as Seaforth Kinergetics, Sub Sea Services, OME,
Aqualogistics, Foundrometers, Submarine Products, Clearbrook Engineering,
Magpie, Mara Engineering, General Diving Systems and Spiro Diving Services. In
1997 the merger with UWI Circle further strengthened Divex as a major player in
the supply of technological expertise and equipment for the subsea industry.
Arawak V

|
The Arawak V
helmet is an early Divex product. It is a 3 light helmet, the diver was to move his head
inside it. The Arawak V is a closed circuit (push-pull) diving sysstem
that supports the saturation diver indepths of water from 200 to 1500
feet. It is especially designed for commercial use. The first time the
push-pull concept was succesfully operational, was in the sealab projects
with Arawak I and II equipment.
Breathing gas is taken from
the atmosphere of a saturation system, wether PTC or submercible, and
pumped to the diver through an umbilical. Diver exhaust gas, in turn, is
pumped back to the bell for co2 scrubbing, reconstitution and reuse.

Ultrajewel 601 "Dirty
Harry"
The
'Dirty Harry' closed circuit diving system is designed to provide a safe and
efficient surface supplied system which minimizes the risk of contact between
the diver and the water in which he is diving. The basic method of achieving
this is by providing a closed circuit breathing system whereby the divers
exhausted gas is returned to the surface and exhausted to the atmosphere rather
than exhausting into the water. The helmet is attached directly to the drysuit.
The proven Ultrajewel 601/17c Reclaim Helmet is used in conjunction with a Diver
Panel, Exhaust Control Panel and the 'Dirty Harry' Drysuit which is available in
various materials. Major Components & Function Ultrajewel 601 Helmet
Assembly The Ultrajewel 601 17c Reclaim Helmet consists principally of the Divex
Ultraflow 601 Demand regulator and Ultrajewel 601 Exhaust Reclaim Regulator
fitted to a Superlite 17c Helmet. The Ultrajewel 601 helmet is suitable for
diving depths up to 450msw (and conforms to the HSE/NPD Work of Breathing
requirements) and is designed to provide fully closed-circuit demand and exhaust
functions which minimize the risk of water from the diving environment entering
the diver's helmet. The Ultrajewel 17c helmet has the patented Ultrajewel 601
exhaust regulator. It is so simple it has only two moving parts and this two
stage valve provides diver security. The DIVEX Ultraflow balanced 2nd stage
regulator overcomes pressure fluctuations in the supply system allowing the
valve to provide adequate breathing gas under all conditions. Typically, the
pressure losses experienced in many dive panels and umbilicals often lead to a
regulator not conforming with the HSE/NPD Guidelines for Breathing Resistance.
The Ultraflow regulator permits a wide range of pressures to reach the helmet
(between 5-20 bar) and still performs within the Guidelines. The helmet neck
ring is bonded to the 'Dirty Harry' suit to prevent potential water ingress at
the neckseal. Courtesy of Divex.
