Walk in Coolers are essential for restatant owners and farmers
and anyone else who has large quantities of perishable foods to store.
Unfortunately commercial walk in coolers are expensive even though the
basic components are not so epensive.
DIY Walk in Coolers may be built for less than $1000. They should be placed on a flat surface tilted towards
the door so that condensed moisture has a place to drain. The walls and
floor and ceiling should be insulated with 4" of solid insulation. The The
floor insulation should then be covered with plywood.
All holes and cracks should be filled with spray foam.
This covers the framing and the insulation But we still need a source of cold air.
An air conditioner placed high on one of the walls makes a great,
inexpebsive source of cold air.
Unfortunately air conditioners are only designed to cool a room down to
To bring a room temperature below 60*F the air conditioner sensor must
be tricked into believing that the room temperature is warmer than it realy
is. This is the job of the COOL CONTROLLER. It keeps the air conditioner
on with a heater probe untill the cooling fins of the air conditioner
approach 34*F or whatever temp the controller is set for above freezing. if
the fins get too cold ice forms on the fins, no air circulates and the
cooling stops.The CoolController or the COOLBOT may be used to bring room
temp. below 70*F
