• 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: 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 The nominal filter appeared in ThermoCube's manual is with the  Pentair/Pentek polypropylene housing which has 3/4 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. Also needs caution whether filter is compatible with <0C coolant. The filter output end should be fitted with the 3/4" NPT shutoff as those on the chiller unit. Filter inlet (fitting unknown) needs to can also apply CPC with 3/4" NPT shutoff to transition to 1/2" tuber 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. 

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.

The vacuum chuck has 3mm diameter hole for the vacuum line tube (OD/ID=3mm/1.8mm). The vacuum pump at B84 EPP lab is a GAST DOA-P704-AA with max pressure of 4 bar (60 psi). The left port (looking from front) has a 3/8" barb that we intend to connect a braided firm polyurethane rubber tube (McMaster-Carr #51165K12) with ID:OD=3/8":5/8" which runs ~1.5m from below the table to the top of table. This pump vacuum tube then transitions to the short (~30cm) 3mm OD vacuum chuck tube with a pair of Aluminum low-pressure (up to 125 psi) 1/4 NPT adaptor to barbed tube fitting: 3/8" barb - male NPT (with O-ring) on pump side (McMaster-Carr #5058K451); 1/16" barb and female NPT on module side (McMaster-Carr #5058K641)shut off valve and vacuum gauge in the transition region so that vacuum on the cooling unit can be held with monitoring after pumping.  Since the vacuum gauge connection are mostly SS, we also opt for SS parts: Push on hose fitting (McMaster-Carr #53515K31) with 3/8" barb for pump tube transition to 1/4" NPT followed by On/off valve (McMaster-Carr #45395K216) and 1/4" Tee (McMaster-Carr #4452K432) for vacuum gauge mount. The Tee port is compatible with Vacuum transmitter McMaster-Carr #3278N1, or an Omega OEM device, both with SS 1/4" NPT mount. The final connection to the vacuum chuck tube could use a nylon part with 1/16" barb and 1/4" NPT (McMaster-Carr #5153K37). Unfortunately here is no SS bodied corresponding part. The 1/16" (1.59mm) barb is a approx match to the vacuum chuck tube with ~1.8mm ID (adequate tightness to be verified).
