Will this be effective in a transit size van full of 5L bottles of liquid chemical? I have a lot of condensation issue due to volume of liquid

Yes it will but make sure you buy enough of them. I had 4 in a steel storage container

Are they reusable and how do you dry them out.

They are not reusable and will last approximately 3 months depending on the environment. They cannot be dried out they have to be deposited at the local recycling centre. We used it in our beach but everything was kept dry not a sign of damp, mildew or mould since we put it in at the end of Ice beginning of November and replaced it last week

What are the dimensions of the various products?

I am sorry but I don't know the dimensions. I can't even tell you how good the product is as I put two in my small Campervan and parked it up for the winter while I go home to New Zealand. I will put a review after I get back in mid June. T

How many poles would be required for a standard 20ft container? And over an English winter how long would they last/need repacking?

We recommend 6kg of desiccant for a 20ft container which is equivalent to 4 x our ‘Blanket’ type container desiccants. Their lifespan will vary based on conditions over the winter and whether the container will be opened regularly or not. The minimum time lifespan is 6 weeks, but they could last up to 3 months if there was low humidity and the container was kept closed. However, they can be checked regularly after 6 weeks to see if the packets are full and if they require repacking. Thanks Britwrap Packaging
