Columbus has dealers for refrigerators and freezer parts available. Freezers are a more concentrated form of refrigeration, which is maintained below the freezing point of water. This is used for storing meats, ice, and other long-term storage items. These are insulated storage compartments that come with a heat pump. The pump transfers heat from the inside of the fridge to its external environment, keeping the interior of the fridge cool, so the foodstuffs do not spoil (it retards the growth of bateria due to the low temperature). Components of a freezer include trays, ice boxes, refrigerating gases, compressors, and other mechanical devices. These may need to be replaced or refilled occasionally, and can be bought from Columbus dealers. Manufacturer, make and model specifications may also be significant for these supplies.
