In memory of Miguel’s days with
Cryoconcept
Didier Coffy 3/10/2005
Some illustrations, underlined in red of
Miguel’s participation as support to
Patrick PARI transfer of technology to
Cryoconcept.
The first international market was the
japanese one directly link to Miguel’s
strong frienships and relations in Japan.
Then the planning of development of
Cryoconcept has the target to share the
turn over between Japan, US and
european market .
As application the US and France market
(outside CEA) was open, England and
Germany are following

CRYOCONCEPT provides Gas Handling
Systems safely controlled by a
programmable controller installed
inside the control panel. This unit can be
placed in the laboratory remote from the vacuum
pumps. The dilution refrigerator can be remote
controlled by computer through the Ethernet port of
the programmable controller.
Picture 1: Gas handling system provided with a
600m3/hr ROOTS pump and a 40m3/hr rotary
vane pump. Mixture injection is made at 4 bars
via a compressor.
Picture 2: Control panel of the 200µW GHS
allows control of pumps and valves and
monitoring of pressures.
Picture 3: Remote control panel installed on a
computer. This software allows control of the Gas
Handling System by communicating with real
time software running on the programmable
controller.

We had heard such a sad news that Dr. Miguel
OCIO passed away on December 2003. He was
not only a great scientist of physics but also
excellent designer of refrigerator. It was great
pleasure to work with him last several years and
we appreciate his kind cooperation for our
dilution refrigerator business.
Always he was smiling and provided us proper
technical advice and gave us better solution for
problems we had.
As his wish, we continue the business of dilution
refrigerators and we will work hard to prosperity
for Cryoconcept with our best effort.
And we would like to express our sympathy to his
family.
