First built in 1962 the Easicool is an environmentally friendly coolbox,
which works on the evaporative principle,the transfer of latent heat by
absorption. No gas or electricity is required just a cup full of water
added daily to keep the liner moist. The water is then carried around the
inner cabinet & as it evaporates the interior is cooled.
It is not a refrigerator but it will continue to work long after an ice
pack has melted in a standard coolbox.
They are ideal for camping, caravanning, boating & all outdoor pursuits.
