A) Application section (2*140cm): Our application tubing came with the CERN shipment is a Saint Gobain Tygon S3 E3603 NSF-51 with 8mm ID/11.5mm OD that fit well onto the cooling block barb (ridge ID/OD=0.306"/0.363"=7.8/9.2mm). To avoid adapting metric-Imperial tubing, we also tried a 1/4" soft tubing and that seemed to just about being able to get on the cooling block barb with very tight fit. Since we may never dissemble the cooling block after initial assembly, we opted to go with the 1/4" ID and 3/8" OD tubing so that the two ends can fit onto the Swagelok Instrumentation quick connect QC6-316 (SS-QC6-D-600 / SS-QC6-B-600) with 3/8" fitting. Aiming for the same soft PVC Tygon chemical tubing as the original CERN part with ID/OD=1/4"/3/8" corresponds to McMaster-Carr #5155T26. Do we need a shut off valve near module to allow faster warmup ?
B) Application joint to chiller Process In (30+15cm): Application joint is QC6-316 ( SS-QC6-D-600 / SS-QC6-B-600 ) as for A) with 3/8" OD tube ( McMaster-Carr #5155T26) for ~30cm then transition (with McMaster-Carr #91355K32) to a short (~15cm) 3/8" ID tube (McMaster-Carr #5155T34) to fit onto the 3/8" hose barb from the HFC 12 series (rating only down to 0C ?) which can connect with the 3/8" CPC at chiller Process In.
C) Application joint to filter (or Process Out) (30+15cm): similar piece like B), such that the hose barb end can plug directly into the chiller Process Out, or filter out.
D) Filter: The nominal filter appeared in ThermoCube's manual is with the Pentair/Pentek polypropylene housing which housing (Grainger #1ECR5) which has 3/4 8 NPT female interface. Other auxiliary components also can be found at Grainger: Mounting bracket, wrench. ThermoCube recommended filter cartridges are the 5 micron particle filter which can be selected from the list Pentair/Pentek filter cartridge (Grainger #3FRU1). Also needs caution whether filter is compatible with <0C coolant. The filter output end should be fitted with the 3/48" NPT shutoff as those on the chiller unit. Filter inlet can also apply CPC with 3/4" NPT shutoff to The short section from filter inlet to chiller Process out doesn't need disconnecting at the filter housing after the initial installation so can just take a fixed 3/8" MNPT to 3/8" barb fitting to transition to 1/2" tube over the 3/8" hose barb to connect to the chiller Process Out, with same connection at both ends.
E) Jacket insulation: We need to insulate all sections of tubing with foam jacket to allow running coolant <~0C. It may be simplest to use a long continuous slitted piece with large enough radius. may be simplest to use a long continuous slitted piece runs over everything. A 7/8" ID and 1/2" thickness slitted tube is envisaged and the ID is mainly constrained bu the hose clamp profile.
