Infinito

This page is about the Rebreather INFINITO IAMT 444 and IAMT 888. It was the end of the 90’s and the INFINITO project grew thanks to the collaboration of a mixed Anglo-Italian group, Powerbreathe. Vittorio Bianchini and Stewart Clough where the creators and implementers of the project. At that time INFINITO was the second CCR beside the more popular BUDDY INSPIRATION, which was beginning to assert itself on the market.

The Infinito  CCR is the first closed circuit rebreather produced in Italy from a group of  international  investigators and technicians who collaborate with NASA and other agencies of technological research. The Infinito should be an extremely sophisticated machine, planned to be built as multiple versions unit, from the use as an  recreational unit, or to specific needs  for  combat or military use  or in the navy. The Infinito is the apparatus used by Claudia Serpieri and Vittorio Bianchini ans Steward Clough of Infinito LTD

I received information the development of the Infinito by Powerbreathe S.P.A. has stopped. I managed to get some additional information on this unit and some pictures thanks to Gibbo. There seem to be developed two units, the IAMT 888 a fully closed circuit rebreather and the IAMT 444 FC, a semiclosed unit and a pure oxygen model.
Here you find additional information:

Later on, a sequel to this development came in the form of the lungfish rebreather, about which more on this website in the chapter The Monitor

Matthias Voss send me a translation of the English specifications on Friday 14-07-2000, I am very grateful to him for that!

Author: Matthias Voss

here is what I get out of it, I tried a somewhat literal translation
with minor respect to common rebreather speak:

IAMT 444 SC/ O2
semi closed / fully closed with oxygen
Both systems share the same fundamental structures.
(JW Bech; there are 3 systems mentioned on this page, 444,888, end SC/Ox)
The breathing bag is inside the center structure (would call that box) and
the tank (mix or oxygen) is held below the central piece by a
specially shaped construction ( I think this is like a Draeger Dolphin)
The integrated weights jacket comes in different sizes and aids easy donning.

Monitor System
On request the system comes with a monitoring system :
Leds inform about :
depth
medium ppO2
separate ppO2 as shown by each of the three sensor cells
temperature within the breathing bag
battery status

In this case the unit comes assembled with the relevant sensors and
depth transducers, which range can be preset from 5 to 20 bars, according
to operating requirements.

Specifications:
weight : 15-18 kg, according to bottle
height : 550 mm
width : 330 mm
depth : 195 mm
scrubber : 1,75 to 2,5 kg
bag volume : 6 to 8 litres
jacket size : small, medium, large
materials : steel aluminium, titanium on special request
monitor system : LED ( matrix) variable luminescence
batteries : C-cells alkaline or Lithium


IAMT 444 FC ( fully closed)
The ECCR has one oxygen, one diluent bottle situated at the sides of the
structure, or alternatively below, lying flat ( “seems to me like
Mares) held by a specially bent metal construction.
“Same jacket as above.

Modes of operation :
Comes complete with monitoring system.
The unit comes assembled with the relevant sensors and depth
transducers, which range can be preset from 5 to bars, according to
operating requirements.
Leds inform about :
depth
medium ppO2
separate ppO2 as shown by each of the three sensor cells
temperature within the breathing bag
battery status

Digital dive management module ( DDMM)
the IAMT 444FC can be bought with a DDMM and integrated Dive Computer,
which will give
decompression info in real time,
 keep record and shows data of the following dive parameters : dive time,
 temperature of breathed gas,
 both pressures of diluent and oxygen bottles,
NDC limits -OR- remaining scrubber exhaustion time,
speed of ascent and descent,
set points,
warning messages,
check list,
decompression information,
all of the information visualized by the monitor system
(my note : these seem to be 2 different systems, partially redundant(
temp, depth))

The control systems can handle most gasses used in normal diving,
including helium, neon, nitrogen, and oxygen.
 
It comes along with a software by which you can plan your rt table and
preparation of your dive.

Options:
The system can be equipped with an umbilical for surface supplied
diving, which allows tele metering of all diving parameters and system
status to the supervising attendants.

Specifics:
weight : 15-18 kg, according to bottle
height : 550 mm
width : 330 mm
depth : 195 mm
scrubber : 1,75 to 2,5 kg
bag volume : 6 to 8 litres
jacket size : small, medium, large
materials : steel aluminium, titanium on special request
monitor system : LED ( matrix) variable luminescence
batteries : C-cells alkaline or Lithium



IAMT 888 ECCR

The unit comes assembled with the relevant sensors and depth
transducers, which range can be preset from 5 to bars, according to
operating requirements.
The system comes complete with monitoring system
Led’s inform about :
depth
average ppO2
separate ppO2 as shown by each of the three sensor cells
temperature within the breathing bag
battery status

Possible Configurations of electronic control modules
(” read redundancy)
single monitoring/ controlling system with double energy pack
single monitoring/ controlling system with second monitoring system
double monitoring/ controlling system with double energy pack each

DDMM
Each of the above configurations can be complemented by the digital dive
management module and control computer ,which will give
decompression info in real time,
keep record on show data of the following dive parameters : dive time,
temperature of breathed gas,
both pressures of diluent and oxygen bottles,
NDC limits -OR- remaining scrubber exhaustion time,
speed of ascent and descent,
set points,
warning messages,
check list,
decompression information,
all of the information visualized by the monitor system
(my note : these seem to be 2 different systems, partially redundant
(temp, depth))

The control systems can handle most gasses used in normal diving,
including helium, neon, nitrogen, and oxygen.
 
It comes along with software by which you can plan your runtime table and
preparation of your dive.

Options:
The system can be equipped with an umbilical for surface supplied
diving, which allows tele metering of all diving parameters and system
status to the supervising attendants.

weight : 30 kg with steel bottle
height : 557 mm
width : 395 mm
depth : 200 mm
scrubber : 1,75 ; 2,5 kg, and 3,5 kg
bag volume : 6,8 to 12 litres
jacket size : small, medium, large
materials : steel aluminium, titanium on special request
monitor system : LED ( matrix) variable luminescence
batteries : C-cells alkaline or Lithium

Guys , that’s all I got from the Info sheet they sent me, let me add that
there is shown a bailout system and a rather rectangular cut shaped
bent drilled drilled drilled metal backplate, protecting at the same
time the down pointing valves.
There is a nice handle which may derive its shape from a Milano
coffeebar ( or Harry’s ;-))

I would still like to know more details, perhaps … well just wait
best to all
