I am a restaurant owner with a 500lb liquid co2 tank similar to the one shown here: http://www.nuco2.com...ts/xactco2.html
I tried to search for my answer on this forum but I am not in the industry and it all might as well be in Latin. So I though I would try the direct approach...
This tank is filled by a company on a monthly basis. Last month I was closed for renovations after getting the tank completely topped off. The company just sent me a bill for 77lbs of CO2 from when we were closed. I checked the entire line and there is not a single leak. When I asked a company rep they said that it is probably because the tank vents off pressure now and then. That seems like a large amount of product loss for venting off pressure in 30 days.
Can someone tell me:
1) What is the normal amount (in lbs) a 500lb liquid CO2 tank would vent off in a month?
2) Is it even the CO2 that is venting or just air pressure?
3) Is it a viable excuse by the company or is something else going on?
I live in Pennsylvania at 525 feet above sea level with the current temperature around 65-75 degrees. The tank is in an enclosed area and does not sit in direct sunlight (just in case that is a factor.)
Thank you.
