- 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.
- 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: Not yet identified the exact part for the filter in the ThermoCube manual. Only the mounting bracket at McMaster is found. Also needs caution whether filter is compatible with <0C coolant. The filter output end should be fitted with the 3/8" NPT shutoff as those on the chiller unit. Filter inlet (fitting unknown) needs to transition to 1/2" tuber over the 3/8" hose barb to connect to the chiller Process Out.
- E) Jacket insulation: At least all thinner tubing section should have foam jacket insulation We need to insulate all sections of tubing with foam jacket to allow running coolant <~0C.
Coolant
We intend to use the ThermoCube recommended coolant Koolance 702 (27% propylene glyco + water mix): https://koolance.com/liq-702-liquid-coolant-bottle-high-performance-700ml-blue. Propylene glyco is a nicer substance (used as food additive in some cases) than the more commonly used ethylene glyco as an alternative antifreeze.
