1.7 nL Nitrogen CGG
This Cool Gas Generator is one of the smallest
in our range with a mass of 45 grams, a
diameter of 16 mm and a length of 60 mm.
When activated it will produce 2.1 grams of
nitrogen gas at ambient temperature.
.
This device is developed for the
RemoveDEBRIS project of the Surrey Space
Center. It is directly based on the 3 nL nitrogen
generators developed in partnership by CGG
Safety & Systems and TNO as part of the
Deploytech FP-7 program.
This generator can be applied for a much
wider range of applications in space as well as
on the ground.

1,7 nL CGG applications
This CGG is a shortened version of the 3 nL generator developed as part of the DeployTECH FP-7
program for use in space inflatable structures. However, the unit can also be used for small cold gas
propulsion systems. Terrestrial applications, like valve actuation or inflation of small buoyancy
devices are also possible.
Cool Gas Generator Technology
This gas generator uses the unique and
patented Cool Gas Generator technology to
supply nitrogen gas.
A cool gas generator consists of a solid block of
material inside a casing. The gas is chemically
stored inside the solid material. A small igniter
starts the decomposition of this block into the
required gas.
Due to our unique design, no external filtering
or cooling is needed for the gas. This results in
very high storage efficiency.
Cool Gas Generators were originally developed
for and deployed in space applications.
There they have proven themselves capable of
working in harsh environments after long term
exposure without any maintenance.
Cool Gas Generators for Nitrogen, Oxygen,
Carbon Dioxide and Hydrogen are in
development.
Cool Gas Generators have a broad range of
applications from space propulsion systems to
inflatable rescue devices. And from breathing
devices for lung diseases to supplying
pneumatic power systems.
Cool Gas Generator Team
CGG Safety & Systems B.V. forms the heart of
the Dutch team that is developing and producing
Cool Gas Generators and their range of
applications.
CGG Safety & Systems and TNO are responsible
for the development and commercialization of
this CGG.
