Anssi: Cryogen free dilution refrigerator is a is a system that you can use to go to
absolute, almost absolute zero temperature. Our product is a dilution fridge which is
based on recirculating helium-3. We have two closed helium loops, one for the pre cooling
stage and one for the dilution fridge stage, but they are both closed loops and that preserves
the global helium supply.
Pieter: The lower you go in temperatures the more sort of specialized knowledge you need
to have to do this sort of business. So this is really a research tool in experimental
physics or Quantum Computing companies that use our tools.
Pekka: Bluefors products have a sub system called high pressure panel, which is actually
recirculating a helium, which is used for creating this ultracold temperature.
Pieter: For our customers, it's very important to have a reliable system. Sometimes it takes
months to tune the system at this low temperature, so you cool it down. you have your system
in the stable state, and then you start tuning the parameters. If you have to stop for whatever
reason, and warm up even like to the to the slightest temperatures, you have to redo the
whole tuning again, that can take months of time for the customer and sometimes customers
really want to be cold for more than a year.
Anssi: The place where we have pure helium-3 at high pressures is done with components
with metal gaskets and all that comes from Swagelok. Swagelok has been the standard fitting
that you use in the places where you want extreme leak tightness.
Pieter: Swagelok parts play an essential role is because they are the ones that actually
contain the helium-3. So the leak tightness is very important in this part. If any leak
would appear the system would just all to stop.
Pieter: We will see in tremendous growth in production. And that's why we have made this
huge cryohall to supply this growth. We did more in the last two years than we did in
the previous eight years of the company not everybody can fit or grow along with the company
that's growing that fast and the trust in the supplier is very important.
Susanna: It is very good to know in advance when we will get the items, so we will our
production will be ongoing and there will be no delays. I think it would cause a big
problem if you couldn't get the items on time because the production would stop and we wouldn't
be able to deliver to our customers on time. So that's why Swagelok's a very good supplier
for us. We have a different level of inventory specially reserved for Bluefors in our warehouse
instead of having it all here at the Bluefors warehouse. Today they have much better inventory
control with their new automated warehousing.
Pekka: Swagelok supports Bluefors engineering team in multiple ways one has been the technical
knowledge that we have and create the high-pressure panel for example as small as possible and
the isolating the high-pressure panel electrically away from the computing system. So we were
able to cut down some of the electronic noise with our dielectric fittings.
Pieter: I believe that scientific growth will help humanity. I think what we do is we provide
solution for the scientist so that they can do their frontier work on new discoveries.
Our customers trust our systems to work flawlessly. And that's why we need to put the highest
quality components inside.
Pieter: I trust Swagelok because the parts are so important that are in the system. We
don't want to make any sort of compromises on quality and Swagelok supports that.
