Why Freezer Stores Ice Up

If you see ice on the floor, thick frost on the evaporator and snow at the door of your freezer store, the source is usually the humid air coming through the door. We explain what that ice costs in safety, product, flow of work and energy, the dry air barrier at the door and where the unit should be positioned.

  • The ice in a freezer store usually comes not from the refrigeration system but from the warm, humid air that enters each time the door opens.
  • Ice on the floor creates a slipping risk for staff and makes forklifts harder to move; doors that ice up also cause trouble when opening and closing.
  • Frost builds up on products and packaging, cardboard boxes soften, and ice on barcodes makes them harder to read and disrupts traceability.
  • As the ice thickens, refrigeration runs longer, defrost comes on more often and the heat entering the room must be cooled away again, so the store falls into a cycle of spending energy.
  • We send dry air down over the door opening to create a barrier that works like a curtain; air is drawn from a point away from the door and the humid air from the unit is sent outside the store.
