Dear AMMRL's:
For anyone who has had experience in designing/installing a ventilation system around an existing instrument:
We recently installed a 300 MHz R2D2 in a room specifically dedicated to this one instrument (area~252 sq. ft). Two Questions:
1.) For the ventilation system/ air exchanger: Is stainless steel OK or is aluminum the better choice?
2.) The engineers want to design the exhaust vent to be positioned directly above the NMR. Like literally inches from the N2/He Vent Tubes. I think this may be over-engineering. A system that is flush with the ceiling seems sufficient as long as it can exchange enough air/ cycle.
Any help/ advice is greatly appreciated.
