Door Sweeper

Most walk in units have 3 sided door gaskets with the bottom of their door needing a door sweep to seal in the cold air. Door sweeps purpose is to seal the bottom space of the walk-in refrigeration unit between the door and its threshold. It is imperative to periodically check its effectiveness, since it can be torn or poorly seal over time due to deterioration as this saves on energy and effect the cooling load of the unit.
