Integrated is the last of three posts dedicated to shallow depth refrigeration. An integrated refrigerator is totally hidden by the cabinets. The doors in other shallow depths will protrude.
In other words, an integrated refrigerator will disappear behind a cabinet. You can also buy these units in columns in different dimensions and place these products at point of use(appliance term for wherever you want). The main brands are Thermador, Bosch, Gaggenau and SubZero.
