Island freezers are wide, waist-height cabinets that stand free in the shop floor rather than against a wall. Customers walk around them and look down into the frozen stock through sliding glass lids, or into an open top on some designs. Several units are often butted together to form a long run.
They suit frozen categories that sell well on impulse or promotion: ice cream tubs, frozen snacks, frozen peas, parathas and meat products. Because cold air sinks, a top-access cabinet holds its temperature better when browsed than an upright with a door. Stock must still be kept below the marked load line, and lids should close properly so frost does not build up in humid weather.
A hypermarket in Ahmedabad might run an island of frozen ready-to-cook snacks near the billing area, with promotional pricing on the lids. Depending on store design, islands may have built-in refrigeration or be connected to a central remote system.
