Minutes SR1 meeting (14/8/02)

Disscussion points: Rack refurbishment:


a.) heat exchangers. The old ones are not made anymore. New ones may not
be available for some months. We have about 60 "good" ones (i.e. not
completely broken)

Joaquin checked around and found somebody (Josa, ST/CV) for us to check
them, test them, repair if necessary in their work shop and install them. Total
cost would be about 120CHF/exchanger (subject to verification). This is
very cheap and extremely practical. The company (CIAT) did not want to
quote on the test and repair.
As we have this offer, we decided to go ahead with this offer to get it
done locally by ST-CV. The work can be done in September.

After the 60+ exchangers are tested, we will know how many new ones are
required. We will start installing them in the earlier required locations
and later add new exchangers (if needed) on the remaining locations.

b.) rack pipes refitting:
When the heat exchangers are installed by ST-CV they will check the pipes
and decide if they need refitting (after tests)

c.) removal of old circuit breakers: JIG, Josa will check if this can also
be done locally by ST-CV

d.) ventilation units:
All ball bearings need to be changed. Electrical function needs to be
checked. Also temperature monitoring and interrupt needs to be checked
Again, JIG, Josa will check if this can also
be done locally by ST-CV. Obviously costs for c.) and d.) are
additional, they will tell us what price they expect. If the work could
also be done in September it would be helpful, but this depends on the
availability of people.

In a brief summary
ST-CV
1.) 63 heat exchangers: test, repair, install
2.) 34 cuircuit breakers: remove
3.) 34 ventilation units: change bearings, test function (incl.
monitoring, interlock)
 

Actions:


Richard: get ventilation unit documentation from DiPietro

Richard, Heinz: provide 1 ventilation unit+doc to Josa asap

JIG, Josa: check if work for c.) and d.) can be done, costs, and time when
it can be done

Mar, Christoph: provid detailed layout (number, slot in rack) for
exchangers for TRT

Heinz, Richard: provid detailed layout (number, slot in rack) for
exchangers for SCT

Georg, Marco: provid detailed layout (number, slot in rack) for
exchangers for PIX

Heinz: collect info on exchanger location and send to Josa, JIG
