panther1400 Posted September 20, 2011 Report Posted September 20, 2011 I have a system in the palne that hasn't been used for years and I'm guessing its 31 years old the lines have been capped do I need new tank or regulators go bad what is all involved, and how much could it cost, to get a sytem up and woking again? It has a 115 cu tank now where do you recommend going for supplies?
jetdriven Posted September 20, 2011 Report Posted September 20, 2011 I thik a hydrostat is due every ten years on the bottles unles they are composite. Check that.
Awful_Charlie Posted September 21, 2011 Report Posted September 21, 2011 The cylinders have a life limit (15 years for the composite, longer for the steel/alu IIRC), and I think the composite cyclinder runs to about 1800USD. Then you have a hydrostat test, every three or five years, and a regulator overhaul every 6 years. That's the aircraft system taken care of, then you are going to need cunnulas and/or masks, and fill ups. Over here in Europe it was a bit more difficult to get a fill, and when I could get them it was an outrageous price - like around 140USD, so I rented a big bottle from a gas supplier (approx 200USD for 3 years) and then get it filled to 3000psi for 80USD a time - it lasts me between 6 months and a year depending on how many people I take to altitude! If you go down the route of getting your own bottle, you're also going to need a filling adapter, which depending on how complex or simple you have it is going to be another 50-500US So it all adds up, but when you've got the kit, it makes high altitude a breeze. Do learn your human factors and consider your 'Plan B', and get an Oximeter or similar too hth Ben
DonMuncy Posted September 21, 2011 Report Posted September 21, 2011 If you have a steel tank, the legal life limit is 30 years and then requires replacement. I replaced mine last year for a price of just under $1000. And if you do not have the valves, canulas etc, Aerox can set you up with all you need for a few hundred. There are ways to save some. PM me if you like. Don
N9937c Posted September 21, 2011 Report Posted September 21, 2011 Not all steel tanks are the same. A 3ht is 24 year life and a 3aa is unlimited with 3 and 5 year tests respectively. www.airportshop.com/aviation_oxygen/cylinders.html larry
Jerry 5TJ Posted September 21, 2011 Report Posted September 21, 2011 There are several threads on this topic on this site. I suggest you have a look at http://mooneyspace.com/index.cfm?mainaction=posts&forumid=1&threadid=332 for more info on tank types, hydro tests and etc.
