Dry Gas System• 3rd Dry Gas System built for NOvA.– Leaving out a lot of the R&D/Analysis info:
Permeation models The “Rainforest” Test Material selection
NOvA APS Drier System
17
How do you know it will work?• We have done extensive FEA and CFD modeling,
calculations, research, and testing with a prototype system at NDOS and Far Detector have been running +1 year.
NOvA APS Drier System

NOvA Near Water and Dryer System 19
Dry Gas APD Routes:• Flow 0.5 SCFH through 3 rows of 32 APDs in series. – 32 per row *3 rows = 96 APDs in a row
– Flowing through 128 APDs at Far Detector with:– Inlet Dewpoint: -70oC and Outlet -48oC to -33oC– Inlet Pressure: 2 psi and Outlet 1.0 to 1.9 psi– Original dryness spec was -25oC at outlet, APDs are -15oC

Rocking Piston Compressors
• 1/3 HP• Quiet Operation• 100% Oil Free
Erik Voirin
NOvA Near Water and Dryer System 25
Air Dryers
• Pnudri Midas DAS2• Self regenerating desiccant dryers• 5 SCFM Capacity @ -40oC
• We should be able to achieve -70C dew point since we are flowing far less than 5 SCFM, and recirculating the dry air.

Gas buffer Tank and Reservoir
• Buffer Tank– 2 gal 316SS ASME pressure vessel
• Dry Air Reservoir– 30 gal 316SS ASME pressure vessel– ~5 hours of backup dry air
Erik Voirin
NOvA Near Water and Dryer System 27
Backup Nitrogen
• Airgas 5.0 Ultra High Purity Nitrogen• 99.999% pure: $75 per cylinder.• Send sample to Atlantic Analytic for analysis.
• 4 Type K Cylinders– 100-200 hours of backup time.

Carbon and Particulate Filters
• MotorGuard M-100– Removes:
• Hydrocarbon Oil Vapor • Silicone Vapor • Organic Vapor – off all types• Desiccant Dust • Volatile Organic Compounds (V.O.C.’s)
• MotorGuard M-30– 0.01 Micron Removal Rating

Safety Documentation
• Water System Piping Note:– Not needed per FESHM 5031.1: Class-D water system.
• Drier System Piping Note:– Completed and reviewed.
• Two ASME Pressure Vessel notes (Air Tanks)– Completed, need to be reviewed
• Electrical Note– To be completed after specification installation of power.
