Custom-built 20 ft container van
Van construction thoughts etc.
Needs better insulation if at all possible. We have had problems in the past with the van
getting too hot. If possible a higher level of insulation in the walls of the van would
reduce this problem.
We have now installed a second 9000 BTU cooling unit in the lab part at the opposite end
of the van and temperatures are much better. This second unit adds to the 10,000 BTU
of the original system.
This second unit is two-part system such as used in houses etc., where the heat exchanger
is separated from the cooling unit. This kind of system requires professional installation
and is more expensive.

area and the lab area to stop water coming over.
