  7. CRIOTEC answered on January 16: they agrees on all the technical options we proposed. Here below their ideas in particular on the recirculation loop not present in our drawings. CRIOTEC did not provide any detailed drawing in addition to ours. They would however give us the executive drawings with all the detailed mechanical and thermo-dynamical calculations, if we decide to accept their offer

  8. Their planning…

  9. CRIOTEC is very interested in the project and ready to accept hints and suggestions, as well as collaboration with other companies for reducing the costs. They are mainly interested in the technical studies and strongly suggest to buy ourselves all components they have to buy from other companies. This could allow us to save quite a lot.- However, we requested a second offer to CARBAGAS (Air Liquid CH). They forwarded the request to Cryotherm GmbH & Co. KG, Germany, specialized in dewar construction.- We also have an independent offer for the cryogenic pump (Barber&Nichols) as well as offers for filters from Messer Schweiz AG. They are ready to deliver at least 2 sets of large filters with any type of connection in 2 weeks.

  10. Criotec offer breakdown and actions Note: CRYOTHERM is only expected to provide the dewar and the inner tube

  11. Late contacts with CRIOTEC We required(30/01) to CRIOTEC a more detailed drawing or a preliminary project were more technical details are discussed. They answered positively to our request and asked for few days to answer about the timing and if we need to pay any moneys for this second step.They also said that are ready to invest in terms of work on this project and to postpone any moneys request in case we give the commission of the project.
