Dun,
I'm also looking to buy a tank could you recommend one, like a model from Nasco I would be breeding approximately 20 – 30 head per year.
What would be a good storage time? Opening? Ect.
Thanks Steve
Just my preferences:
2 inch neck opening, 20-25 liters of LN2, 6 canisters
A samller neck opening is a real pain, and even though they will hold longer and hold more canisters, each canister is so small you can't get more then two canes in each one. Well really you can, but trying to get them in and out of the canister is a real art (magic).
A working time of 120 days on up will put you in the 3 1/2 -4 month refill time. It depends on your nitrogen (semen) supplier as to cost and when he is in your area on the regular route.
Our old pain in the butt tank held for almost 8 months working, but it was
very heavy, well over 100 lbs full. I'm sure the equivelent tank would be lighter today because of inproments to insulation and shell material, it was stainless, the newer ones are aluminum.
A question for the folks that are thinking on buying a tank to get started. Have you checked with your local vet, dairy, neighbor about renting storage space in their tanks. We used to charge 5 bucks a year per canister if I remember correctly. At one time we also ran a storage co-op that all members paid an equal percentage of the purchase and the yearly nitrogen fees.
Just thoughts
