G'Day Fellas,
In my never ending search to find cheaper gas, I found that the best price I cound get for a refill of my 5kg CO2 fire extinguisher was $50 + GST, a 20km drive and a few days wait for the return trip to pick up the cylinder. I rang BOC and found I could get a VT size bottle from a local distributor for $40 + $9 per month rent. I figured why not rent the bottle for a month, then on the last day, fill my fire extinguisher and return the bottle. Now I am looking for any one with experience in decanting between bottles. I was thinking of seeing the guy that sold me the cylinder and seeing if I could get two of the hoses that were originally on the extinguisher and join then together by whatever means to create a decanting hose. I would assume that the VT bottle would need to be inverted to get the liquid CO2 flowing though the hose and into the fire extinguisher. Also, as I use CO2 at work to make dry ice, I know the decanting process would get very cold. Could this cause blockages thereby subjecting the decanting hose to the full pressure of the VT bottle ? Are there any hidden dangers trying this ? it seems a similar process and a whole lot less dangerous that getting your LPG cylinder refilled down at the local servo by the teenager behind the counter.
cheers
