Yes, I believe for the pressure control system to operate, 35 psi is
required at the inlets of the mass flow controllers.<br>
<br>
I have attached my narrative on MVT gas mixing system operation.<br>
<br>
Thanks,<br>

<pre wrap="">Hi Maxime,
If the MFCs are functional you may flow argon. The system is operational from a pressure systems standpoint.
George,
I saw the argon regulated to ~15 psig this morning. What do you recommend for MFCs inlet pressure for operation, 35 psig?
Matt

Subject: Electricity for heating blanket and heat tape
Dear George, Dear Matt,
I went this morning with Jason to take a look at what needs to be done
for having electricity for the heating blanket and the heat tape. Jason
will certainly go back there this afternoon with an electrician around
3pm. George, can you please go with them?
Once the electricity is installed for the blanket, I will start testing
and using the mixing system. Is it OK? (I would like to already use pure
Argon, can I?)
Kind regards,
Maxime
