I have spoken to several local business parks,
Several do not have the required 5.5 metter ceiling height
required to service the bigfoot dewar,
but might have tall enough ceilings to fit the fiberglass dewar.

What are the outer and inner dimensions of the fiber glass dewars
like the last one you installed?

What height is needed above it to lift caskets in and out?

Are the chests stored in layers or upright?

Seems like a lower height would be needed if the chests are stored horisontally.

What is the boiloff rate?
What have been the boiloff rates of your various fiberglass dewars so far?

How much liquid nitrogen fits in one such dewar?

How much can boil off before one has to refill it?

If one can refill 900 liters a time, then this can be done directly from a large
and we can get a very good price on the liquid nitrogen,

delivery trucks in Norway are 18 meters long and have a house that are from 5 to
8 meters long.I am looking at facilities where the truck can drive to within 5 
meters of the dewars.

With the bigfoot this has to be topped off manually every 14 days from 196 liter

with the fiberglass one might be able to fill it directly from a huge truck once
a month?
