1000ltr IBC tanks and all of the other whyvale tanks are simply meant for storage only in situe not in transit,I think most of us get confused because at the start of WFP all suppliers used this type of tank incorporated with there systems. Those tanks are 100% not baffled in any way a 1000 or 500 ltr bucket would be a better example of them,you drive a van with a baffled tank and then drive one with an un baffled tank a few miles down the road will prove my point along with pulling up at the traffic lights. Close your eyes for 30 seconds it'll feel like your crossing the channel on the ferry,just simply ring Neil and say is that right the above tanks are baffled is that right,for the next 10 minutes you'll get an explanation of why there not along with a huge amount of bad launguage lol.
