Evaporators are an essential part of a walk-in cooler, or freezer. As air passes over the cooling coils moisture builds up and freezes. Each evaporator has a defrost cycle to melt frost/ice that has built up on the coils. Water from this melted ice is drained … usually. If not, then a block of ice takes over causing the compressor to work harder. When ice buildup is excessive, the compressor will run all the time and the freezer temperature set point will not be reached. You may also notice stalactites and stalagmites of ice appearing in your freezer – take quick action to avoid costly damage! Operations and maintenance issues should be addressed to avoid costly repairs as well as potential product loss. Bush Refrigeration specializes in cleaning and repairing commercial equipment.
