Vera Mainz, Director of our VOICE NMR Lab, forwarded your request
for information regarding liquid nitrogen tanks to me.
We have just completed the campus bidding process for a liquid
nitrogen supplier. The contract was awarded to Air Products. The other
major vendors, such as Praxair and Airco, offer similar services and
products, though.
As far as general cost information, the purchase prices for liquid
nitrogen tanks are approximately:
3,000 gal. - $32,000
6,000 gal. - $47,600
9,000 gal. - $64,900
These prices do not include any piping or vaporizer units. Since
these costs are beyond our budget, we presently rent our tanks. Rental
prices on similar tanks are approximately:
3,000 gal. - $320/month
6,000 gal. - $525/month
9,000 gal. - $790/month
These costs include installation and all service/maintenance work.
Other things to consider for a new installation include the vacuum
jacketed piping. This cost runs approximately $325/foot just for the
tubing itself, not including any other fittings, gauges, or installation
labor. You will also need an adequate concrete pad which can support the
tank weight (ours is 15 inches thick, with 21 inches around the tank
footings). If you rent the tank, most suppliers also require a fenced
enclosure for security. A fence is generally a good idea in any case. All
of these items would probably be additional costs to you.
Any of the suppliers should provide free evaluations and cost
estimates to meet your particular needs.
Please fell free to contact me if you need any further information
or have any other questions.
