seen a pick up other day watering flowers in town 800 ltr tankall held on by two straps
i would have added a block of wood at least

[Nathanael Jones]

I saw a truck Monday with 3 full IBC's on the back completely unsecured!! Utter madness!

Your IBC tanks can be baffled by buying land drainage plastic piping from B & Q. Just place them in the tanks and the jobs a good un!

Ever since i started, and i was just a numpty with a trailer, i never understood why a system had to make water.My water was always made at base and transfered, even when i had a roman 300gpd.

I have a 4040 now and i assume thats the best you can get (I may be wrong about that), and could fill as many vans as i like.

The other thing i never understood was having a di polisher on board.Why? I never really had the guts to do away with it, it seemed like an article of faith that you had to have one.I posted on here and dave st ives had dumped his , so i got rid of mine too.

As regards fitting a tank, i'm very pleased with the one i have.It does have a high center of gravity but it does make more room and a better layout.Wydale are rubbish and you have to factor in having a frame made and the time it will take you.

What sort of van are you thinking of?

I got rid of mine in all that cold weather because it was freezing up and was hard to insulate. I also thought I really don't need this so got rid of mine also.

Am i missing a trick here? Why does a 1000 litre IBC need to be baffled?

Are you on commision from B&Q ? What use is that?

[Clive McDonald]

iT doesn't. Full it makes no difference, half full , it's just a bit lurchy while driving.

My 800l is poorly baffled,

[JSMC]

i actually had large  U bolts manufactured for my tank with plates to go around chassis rails biut onc ei removed fuel tank i realised it wouldn't work. they would fould on  it and be of no use

Why would you make such a remark if you don't know what use the pipe is

Any tank that holds liquid needs to be baffled to reduce movement during transport. The force of water (which is heavy) moving around inside a tank can make a vehicle become unstable and put a lot of pressure on the tank itself. The last thing you need is a split tank whilst driving down the road.

The use of land drainage pipe reduces that movement by letting water pass through it and  minimising the slopping about of water when the tank is not full.

Take a look at the pure freedom website, their tanks are baffled. Why do you think that is???

Nice one RG1, one of my vans has an old ionic delivery system back when they used IBCs, it has the plastic pipes in as baffles and now I know what to use and where to get them! I knew this forum was good for something!

[mikecam]

Why would you make such a remark if you don't know what use the pipe is

Because i understand how tank baffling works. Baffling is fine for a long narrow tank (i.e road tanker) where the surge of fluid can cause problems, and the long travel of the liquid creates a surge.. Now an IBC is what roughly? 3ft x 3ft ? So  what does 'baffling' stop in an IBC? Two surges right next to each other within 3 ft? Baffling in the size of tanks commonly used by WFP'ers is a gimmick. If IBC's needed baffling they'd be baffled as they are primarily designed for transportation. I'm baffled why anyone would put baffles in such small square tanks.

[mci services]

I am with mikecam on this debate, I have driven tankers and know how the baffles work, and when in the army drove water bowsers cross country and they were never baffled and held in place with ratchet straps. sent plenty of crashed trucks and no the water container never burst out and killed everyone within 20 feet like some would have us believe.

Do you really think the councils up and down the country would allow their trucks to carry IBC tanks every day if they were unsafe, they are built for being transported to a UN classification

I would be interested where your knowledge of baffled tanks comes from.

Anyway, IBC's were primarily used by chemical plants for the transportation of believe it or not..chemicals. They are usually filled to the brim so no need for baffles. However some may have a certain amount of ullage but  they would have little impact on a forty foot trailer. One half filled IBC in a van though would make for an unstable load and water constantly slopping around. Hence the need for baffles which the drainage pipe from B & Q helps to provide.

I have also driven tankers all over Europe and understand the need for baffles. You are talking about trucks that carry an IBC which is far different from a transit (or smaller) sized van carrying one.

There is a difference.

[Ian_Giles]

Baffling an 1000L IBC tank makes an awful lot of sense, and using land drainage pipes is an inexpensive way of doing so.
These are bulk containers designed for the transport of liquids and when used for their intended purpose they will have a full 1000l of whatever liquid it is they are transporting.
They are not intended for use as a water bowser, and certainly not for us window cleaners.
If you use one as your main tank in the back of your van you should lose the original cage for a start, it's way too weak, and look at the difference between skin thickness in a tank made specifically as either a proper bowser or the ones for WFP.
Massive difference in thickness and strength.

A half full tank with half a metric ton slamming around in there has a huge amount of kinetic energy when you slam on the brakes or turn suddenly, at just 30 mph that half ton becomes several ton!

it makes an awful lot of sense to baffle a 1000L IBC tank.....

Both very true, im looking into the baffle at the moment, I would point out that only 3 companies make cages that do stand up to a collision, as well as bolting to the floor I may also add some heavy duty ratchet straps

Lee,



IMO Call purefreedom and get a 1000L cage and tank, then get your guy to fit it.

Making a frame can be a pain in the ass, I have made 2 now and will not be making the third way to much time messing about for what is not a lot of saving if any after time spent designing it and buying metal, powder coating it etc.



If I am right Steve cm has a 1000L pF delivery in one of his vans.


I would be worried if I sent a guy out with an ibc tank in the back of a van baffling it would make it less that 1000l of water. this cost saving could work out very expensive.

you could also look into a custom designed tank, these are coming down in price all the time, baffled even more than the wydale tanks most use that could be an option for you m8.

I agree.

[Ian Lancaster]

One very important point that everyone is missing is that baffles MUST be part of the structure of the tank.

You boys who drove tankers will know that the baffles are plates welded to the inside of the tank to hold back the liquid when the tank moves.  Loose baffles would simply slosh backwards and forwards with the liquid and do nothing at all to restrain its movement.

Putting lengths of drainpipe inside a tank will work perfectly well, but the pipes must be jammed in together so they cannot move.  If they are just loosely dropped into the tank, the contents and the pipes will all slosh around together as one big dollop of water - the idea is to break up the water into lots of independant smaller dollops.

you have a point there, and may I just state I only have a 400l tank that is baffled, but if you take a bucket of water and soap and possibly urine and plonk it in your boot or back of van it will spill when driving around, however if you stick your applicator in with a couple of squeegies in it, it doesn't unless you brake really hard, or corner badly. my brother also throws in a clean micro into his bucket because it stops spillages in his 4x4 so the drain pipe idea works to a degree and even better if done correctly and safer still just buy a baffled tank, but as far as I can tell the containers ie the 1000l IBC tank is perfectly capable of transporting water as long as the payload allows

800 litre upright. and surprizenly we ain't run out yet. when i had the 1000 layflat we would use more water...strange

Lee it cost me £1600 for a 2 man delivery fitted (reels as well). at that small price it was a no brainer. i would of only saved 300 if i fit it myself but with all the hassle
