Dry Air for MMTS
Rong-Shyang mentioned in his talk at the MAC testing meeting that the MACs will be responsible for the equipment needed to supply the dry air for the MMTS. The specs for this dry air are more stringent than what we're using for our dry air storage cabinets, so at least at UCSB our current air dryer won't work for the MMTS.
Dry air requirements: – dew point <-60C. vs (-16C to -19C at MACs) – Minimum flow rate 60l/min = 2.1cfm – Recommended 120l/min = 4.2 cfm
Options: Manual Dessicant vs Regenerative Heatless
Manual Dessicant
dessicant air dryer inline between the compressor air dryer and the MMTS. These are inexpensive, but would require frequent regeneration of the dessicant
Cost: < $500
Regenarative Heatless:
uses pressure swing adsorption (PSA). The operation is fully automatic and relatively little maintenance is required
Cost : $2000-$4000
